Busting 4 of the Most Common Tooth Brushing Myths – Apex Dentist

, by

Most of us learned how to brush our teeth in Kindergarten—so it’s no wonder we tend to get some things wrong. After all, we haven’t had a proper tooth brushing lesson since we were little kids! Coupled with the fact that tooth brushing best practices have changed over the years, and popular myths that exist about dental hygiene, it’s not surprising that so many people visit our office with cavities and caries, even though they brush every day. Here are some ways you may be brushing your teeth wrong.

Myth 1: After brushing your teeth, you should rinse out your mouth with water.

This is by far the most common tooth brushing mistake most people make. When we were kids, an emphasis was placed on spitting out the toothpaste in order to keep us from swallowing it. However, as an adult, you should keep the toothpaste residue on your teeth as long as possible. Toothpaste works by applying fluoride to your tooth’s surface, in order to raise the Ph of your mouth and remineralize the enamel. Rinsing it off with water minimizes its benefits.

Myth 2: After brushing your teeth, you should rinse your mouth with mouthwash.

Mouthwash should be used before you brush, not after. Unless it’s a fluoride mouthwash, you’ll be negating all the hard work you did by brushing, just as with water. Secondly, you’re also creating a more acidic environment in your mouth that wears your enamel down more quickly.

Myth 3: You should brush your teeth soon after eating.

Brushing your teeth after a meal does a lot of damage to your teeth. All the acid in your food is stuck in-between your teeth, and brushing rubs it around like sandpaper. Instead of brushing directly after eating, wait a few hours after eating so that the saliva in your mouth lowers the Ph. If you’re worried about having bad breath, chew a minty gum containing xylitol. The best time to brush your teeth is first thing in the morning, before you’ve eaten.

Myth 4: Since plaque is tough to get off, I need to brush forcefully.  

Brushing too hard can actually cause your gums to recede, and erode your enamel as well. Instead, brush your gums with light, gentle motions. Plaque is not stuck on hard to your teeth, and brushing lightly will remove it. If your toothbrush bristles have a smashed-down appearance, that’s a sign that you are brushing too hard.

Prehistoric Humans Had Better Teeth Than We Do – Here’s Why from an Apex Dentistry

, by

Our teeth are whiter, shinier, and straighter—but in terms of cavities and tooth decay, they’re not as healthy as the teeth of our ancestors, according to research published in scientific journal Nature Genetics. Learn more about this surprising discovery below.

From Carnivores to Omnivores

In order to learn more about prehistoric humans’ health and diet, an international team of researchers, led by a group at the Australian Center for Ancient DNA, extracted dental plaque from 34 prehistoric European skeletons. (Dental plaque is unique in that it is the only easily accessible source of preserved human bacteria.)

The researchers were able to trace the changes in oral bacteria from the last hunter-gatherers, through the Neolithic, medieval, Industrial Revolution, and modern eras. They found that, as humans switched from an all-meat diet to a diet high in grains and wheat, they developed more and more tooth decay. Their conclusion? While the advent of agriculture might have revolutionized our quality of living, but it wreaked havoc on our teeth.

Researchers also found that early hunter-gatherer groups had greater diversity of disease-associated bacteria. More bacterial diversity means that our ancestors’ mouths were more resilient to stresses and less likely to develop disease.

Bacteria and Tooth Decay

These finding make sense when you think about what causes tooth decay. Contrary to popular belief, it’s not sugar directly that makes teeth rot. It’s actually the bacteria that live on the teeth, who love to eat sugar and carbohydrates. Once they’ve eaten, the bacteria process the gluten into acid which destroys the teeth enamel. The more sugar and grains, the more acid and the more tooth issues.

How to Take Care of Your Teeth, Here and Now

These results are no doubt good news for advocates of the paleo diet—but really, any diet that is high in protein and vegetables will be good for your teeth, as well as the rest of your body. You can also take care of your teeth by chewing gum that contains xylitol; brushing your teeth regularly and correctly; and having regular dentist check-ups.

What are Dental Veneers? Ask an Apex Cosmetic Dentist

, by

Have you ever wondered if dental veneers could help you achieve the smile you have always dreamed of?  It is important to find an Apex Dentist who can help you understand if you are a good candidate for dental veneers and answer all of your questions.  Here are a few to get you started!

What exactly is a veneer?

Veneers, also known as porcelain veneers or porcelain laminates, are super thin shells of ceramic porcelain which are bonded to the front of teeth.  The procedure is often considered “cosmetic” because there is typically little or no decay present.  The goal is to improve your smile!

Why choose a veneer?

Veneers are an excellent choice of dental treatment in many situations. They can often provide a conservative alternative to dental crowns.  This is because the thin shells only need to cover the tooth enough to change it’s color, size or shape, rather than to remove dental decay.
Veneers are can improve a smile in many different ways, such as
-repair teeth that were chipped and broken from an injury.
-filling gaps between front teeth
-masking a tooth that turned gray after a root-canal procedure.
-masking undesirable defects, such as teeth stained by tetracycline
-masking genetic dental defects, such as peg laterals
-masking discolored fillings in front teeth.
It is important to have an initial consultation with your dentist so that all of your questions can be answered.  It is very important for your Apex Dentist to understand all of your objectives.  Are you trying to close a gap or fix a chipped tooth, or both?  Do you want your veneers to match the current shade of your teeth or do you want to whiten your teeth first and then match your veneers to your new pearly whites?  It is critical that your dentist allows you to be an active participant in planning your new smile.

What happens during the procedure?

First your Apex Dentist will prepare the teeth for veneers by lightly buffing about a half of a millimeter of the outer enamel.  As a result you will likely recieve a local aesthetic. After the teeth are prepared your dentist will take an impression in order for the veneer to be fabricated.  If your dentist has the technology to do a digital impression through the use of CEREC technology, you will be able to receive your new veneers in one appointment. This is because as the veneers can be created in the dental office the same day that the teeth are prepared.  After the veneers are created, the teeth are cleaned with a solution that will allow them to achieve an adequate bond. Then the cement is applied and a light cures (or hardens) the cement, attaching the new veneers!
Maintaining your veneers is easy…just treat them the way you treat the rest of your teeth. Brushing, flossing, and regular dental check-ups are vital to protecting your investment as well as maintaining your overall oral health.
You never get a second chance to make a first impression.  See if dental veneers can help you put your best smile forward!

What is Xylitol? Ask a General Dentist in Apex NC

, by

We all know about the negative health effects of sugar, especially when it comes to teeth. Fortunately, artificial sweeteners don’t have the same effect on teeth as sugar, and can help you have a much healthier smile. One artificial sweetener, xylitol, even has positive effects on teeth. Here’s everything you need to know about Xylitol from a dentist in Apex, NC.

What is Xylitol?

Xylitol is categorized as a sugar alcohol. That means that it combines traits of sugar molecules and alcohol molecules to create a structure very similar to that of sugar. However, Xylitol has much fewer calories, doesn’t raise blood sugar levels, and actually kills the harms the bacteria that live on your teeth and cause tooth decay.

Is Xylitol Natural?

Despite the pharmaceutical-sounding name, Xylitol is found in many fruits and vegetables, and is even produced in small amounts by the human metabolism. It can also be processed from trees like birch, or from a plant fiber called xylan. For these reasons, most health professionals consider it to be a safe, natural substance.

How Xylitol Helps Your Teeth

Xylitol functions a lot like a “mousetrap” for the bacteria that live on your teeth. Normally, these bacteria ingest sugar and carbohydrates and convert them into acid, which destroys the tooth enamel. After the bacteria ingest xylitol, however, they are no longer able to absorb glucose. With their energy-producing pathway clogged up, they end up starving to death. That’s why many dentists recommend using xylitol-sweetened chewing gum: it’s one of very few things that can actually kill harmful tooth bacteria.

Why Xylitol is Toxic to Dogs

If you buy gum or candy that contains Xylitol, it is very important to keep it away from any dogs in your house. When a dog eats xylitol, its body mistakes it for glucose and starts producing large amounts of insulin. Then, the dog’s cells start absorbing glucose from the bloodstream, which can lead to hypoglycemia, low blood sugar, and even death. Xylitol may also have detrimental effects on liver function in dogs, with high doses causing liver failure.

It only takes 0.1 grams per kg of body weight for a dog to be affected. To put that in perspective, a 6 pound Chihuahua could get sick or die from eating a single piece of xylitol chewing gum.

When To Seek Emergency Dental Care – Apex Emergency Dentistry

, by

Though inconvenient, a dental emergency is not something you want to ignore. However, you should know the difference between a true dental emergency and a situation that can wait at least for the night. Dr. Rylan Hansen and his team at Hansen Dentistry in Apex, NC are here to provide expert emergency dental care should you ever be in need of immediate treatment. Contact us at (919) 363-8444 to schedule an appointment.

What Constitutes a Dental Emergency?

Often, a tooth will break, chip or crack because you bit something hard, such as ice cubes, an apple or hard candy. Opening chip bags, plastic containers or “easy open” pill bottles with your teeth can sometimes result in the same thing. Some dental emergencies are the result of a traumatic injury or accident. Children can fall on the playground or get hurt at practice or you could be involved in a car accident. If the injury is just a chip or minor fracture, you could decide to wait and seek attention when the dental office opens. However, a severe injury is a different story.

Examples of dental emergencies:

  • Severe crack or fracture
  • A large piece of a tooth is missing
  • A tooth has been knocked out completely
  • A nerve has been exposed

What to do in a Dental Emergency

Here are some things you can do if you (or your child) sustain a tooth injury.

Cracked tooth – See the dentist as soon as possible, especially if there is any pain. Even if the tooth looks “okay” you should still be cautious. If the tooth hurts when you drink something hot or cold come in right away, as it could be a sign of nerve damage within the tooth. Another sign of a crack is if the tooth hurts after you release your bite.

 

Broken tooth – There is usually no mistaking a broken tooth. If there is a large fracture, chip or part of the tooth is missing see the dentist ASAP as there could be nerve damage.

Before you go to the dentist:

  • Rinse your mouth with warm water.
  • If there is bleeding, apply pressure with a small piece of gauze.
  • If the bleeding won’t stop, try using a wet tea bag.
  • Put a cold pack or ice on your lips or cheeks over the area of the broken tooth to reduce swelling.
  • If you absolutely can’t get to the dentist right away, cover the tooth with temporary dental cement from a drugstore.

 

Tooth is knocked out completely – First, try to put the tooth back in the socket. If it will not go back in, clean off the tooth as best you can and store it in a sealed container with milk or your saliva. Apply a cold compress if there is any bleeding.

 

What to do for Tooth Pain

If you develop sudden – or suddenly increased – tooth pain, see the dentist as soon as you can. It could be a sign of tooth decay or damage to the nerve. You can probably wait until normal hours to go in, although it might feel like an emergency if the pain is severe or it hurts when you try to eat or drink.

 

Emergency Dental Care at Hansen Dentistry

Tooth pain can interfere with your ability to eat, drink, work, sleep and even think. A cracked, broken or missing tooth constitutes a real emergency that requires care as soon as possible. Dr. Rylan Hansen and his team at Hansen Dentistry in Apex, NC are here to help, with extended hours, same day emergency appointments, and Saturday appointments. Even if you are not in pain from a cracked or lost tooth, it is still important to come in as soon as possible. The first several hours can mean the difference in saving your tooth.

Same Day Crowns: Long-Lasting Results Without the Wait! – Apex Cosmetic Dentist

, by

Same Day CrownsDental crowns offer natural-looking restoration results for teeth that have been damaged from trauma or infection. Until recently, receiving a custom-made, permanent crown could take weeks; now, Dr. Hansen offers same day crowns in Apex, NC, thanks to advanced dental technology called CEREC. Learn more about this innovative approach to dental crowns below.

If you’re ready for dental crown treatment without the wait, contact us at (919) 363-8444. Dr. Hansen can provide a consultation to see if same day crowns will help improve the health and vitality of your smile.

What is CEREC?

CEREC stands for “Chairside Economical Restoration of Esthetic Ceramics.” It’s a long term, but conveys a simple idea: CEREC allows Dr. Hansen to create and place a custom-made dental crown in one day. Previously, custom dental crown fabrication meant sending impressions off to a dental lab for a dental ceramicist to create the restoration. However, our practice’s state-of-the-art machinery uses 3D images obtained from your mouth to create a replica of your natural tooth. Dr. Hansen can make any small adjustments once the crown is placed to ensure that your bite is comfortable.

What are the benefits?

CEREC has so many benefits; for our busy patients, less time at the dentist’s office is the best advantage. However, CEREC also:

  • Allows for same-day restoration of your smile: A healthy, restored smile now doesn’t have to mean long treatment times. Whether Dr. Hansen is protecting a vulnerable cracked or chipped tooth, or is finishing a root canal procedure, you can have your final, permanent smile completed in just one day.
  • Uses the same, high-quality materials: CEREC crowns are made from the same materials as those of many traditional dental crowns. CEREC just allows Dr. Hansen to bring the technology of dental labs into his Apex, NC practice to save you time.
  • Provides a comfortable design process: Uncomfortable dental impressions are unnecessary for fabricating a CEREC crown. Dr. Hansen utilizes a 3D imaging device to provide accurate measurements.
  • Eliminates the need for temporary crowns: Since there is no waiting period while the permanent crown is fabricated in a dental lab, patients don’t have to spend 2 to 3 weeks wearing a temporary crown. Temporary crowns are usually made from composite resin and are not only less durable than a permanent crown, but are less protective, too. With CEREC, your tooth is better protected through a permanent crown than it would be with a temporary one.

Are the results really permanent?

Fast results don’t have to mean low-quality. Dr. Hansen and our team know that you have a busy schedule, so we offer time-saving solutions for dental services. However, we never skimp on the quality and safety of the procedures. CEREC crowns are fabricated from the same safe and effective materials used at more traditional dental labs. You can also expect CEREC crowns to last the same length of time as a traditional crown.

How can I receive a CEREC crown?

Scheduling a consultation with Dr. Hansen is the best way to figure out whether a CEREC crown will work for you! Dr. Hansen can go over additional treatment options, and discuss your expectations to make sure you are fully satisfied with the results. Contact our Apex, NC practice at (919) 363-8444.

The CEREC System: State-of-the-Art Technology from an Apex cosmetic Dentistry

, by

If you have ever dreaded the idea of visiting the dentist or have postponed scheduling dental work you knew you needed, you are not alone. Dental procedures have changed for the better, and at Hansen Dentistry in Apex, NC, we blend proven techniques with outstanding customer service.

Would you believe us if we told you that you could receive customized, natural looking crowns or bridges that fit perfectly, in a single office visit? Believe it! Dr. Rylan Hansen and provides custom dental crowns and bridges using the CEREC system: where old school service meets state-of-the-art technology.

What is CEREC?

CEREC stands for Chairside Economical Restoration of Esthetic Ceramic. Like the name suggests, each restoration the system produces is made from ceramic (read: no more metal!).

If you opt for a CEREC crown or bridge, you will not need to endure traditional putty impressions that often cause gagging. Instead, Dr. Hansen will use a 3-D imaging system to gather all the data necessary. You also will not wait days or weeks while a lab technician creates your restoration, then return for a second visit to have the restoration placed. Even better, you won’t need to wear a temporary crown that could come loose and cause embarrassment or hassle.

How does CEREC work?

After imaging your teeth, Dr. Hansen will use CEREC software to design your custom restoration, for a secure fit and balanced bite. He will insert a CEREC Block that matches the shade of teeth surrounding the location of the restoration in your mouth. The CEREC Block will be turned, sculpted, and contoured in the system’s milling unit. This process takes about an hour.

After the dentist provides a local anesthetic to numb the affected area, he will seat the custom-made crown or bridge. Once he determines that your bite is properly aligned with the new restoration, Dr. Hansen will permanently cement it in position. Your CEREC restoration will look and feel totally natural, and it will endure for many years to come.

With same-day service, you will save time and leave your first visit with a restored smile. No metal, no waiting, no fuss. This is certainly not your father’s dentist!

Chairside Economical Restoration of Esthetic Ceramic (CEREC) is changing the way we think about restorative dentistry. CEREC is an effective, affordable service that brings together the customer service and care that patients expect and the high-tech performance and outstanding results they want.

Give CEREC a try.

Ready to give our CEREC same-day service a try? Contact us at (919) 363-8444 to schedule your appointment. Let us answer your questions and explain the details about CEREC.

Dr. Rylan Hansen and our team at Hansen Dentistry proudly serve our patients, listening carefully to all concerns, and providing solutions for great oral health. Learn more about the variety of dental services we offer, including family and pediatric dentistry, along with cosmetic, restorative, and surgical procedures.

How Cosmetic Dentistry Gives You More Confidence – Apex Dentist

, by

brunette woman hiding smile behind handsIt’s nice to imagine a world where looks aren’t important, but we don’t live there, do we? The truth is, the majority of the population will initially judge us based on our appearance. The first attribute most people notice is the eyes, followed closely by the smile. Crooked, discolored, or missing teeth send the message that a person does not take good care of himself. An unattractive smile also conveys poor health and can make you look older than you are.

Fortunately, we live in the age of cosmetic dentistry, when a visit to Dr. Hansen’s Apex, NC dental office could change your smile and the impression you make.

What They’re Really Thinking

These aren’t just assumptions. They’re facts. The American Association of Cosmetic Dentistry has published polls telling us that with an appealing smile, a person is more likely to be thought of as healthy, confident, wealthy, and friendly. A study by Kelton Research went further to state, after teeth whitening, job applicants were more likely to be hired and receive a higher salary.

Strip the emotional sting of being judged by looks out of the equation, and it makes sense to improve your smile’s appearance if you don’t naturally have an appealing smile.

What is an “attractive smile?”

The traditional attractive smile in the United States has:

  • No missing teeth
  • Straight teeth
  • White teeth
  • Teeth with the traditional tooth shape, no imperfections
  • No chipped or cracked teeth
  • No metal dental work
  • Teeth have natural reflectivity (don’t look dull or fake)
  • Teeth that are proportionate to the facial features
  • Symmetrical teeth, right and left
  • Only a small amount of gum tissue showing above top teeth
  • Healthy gums
  • Fresh breath

How can cosmetic dentistry help?

Correcting your smile’s imperfections is possible with cosmetic dentistry. Dr. Hansen will need to talk with you about what you love and hate about your teeth, and he’ll also conduct a thorough oral health examination. All cosmetic restorations should be build upon a healthy foundation, so they’ll endure the test of time. Oral health is also paramount to overall health, and your health is of utmost importance to us.

Dr. Hansen will suggest the appropriate cosmetic dentistry procedures to brighten, straighten, and correct your teeth. He may also recommend a periodontal (gum tissue) procedure, if appropriate. You will have options. For instance, porcelain veneers can correct the size, shape, alignment, and color of your teeth. However, you may opt for dental bonding instead. Bonding does not last as long as veneers, but it also does not cost as much. However, porcelain veneers cover the entire front surface of a tooth and can look new for many years. Dr. Hansen will inform you of the pros and cons of various treatment options, so you and he can devise a practical treatment plan that will deliver the smile you want.

A Dentist for Every Member of the Family – Apex Family Dentistry

, by

family dentist

At Hansen Dentistry, we know that raising and caring for a healthy family is one of the most important things in life. That’s why we’ve made our practice a place that helps every member of your family have the best oral health possible. From the youngest to the oldest, you’ll find that we are your one-stop family dental care headquarters. As a family dentist, Dr. Rylan Hansen is trained in caring for teeth and gums at every stage of life. Visit our Apex, NC dental office to learn more about our services.

Children’s Dentistry

The key to keeping children’s teeth healthy is prevention. Children should come in for routine oral care starting at their first birthday, with regular six-month visits. At preventive visits we give children a check-up, provide a gentle cleaning to remove tartar, and apply preventive treatments to strengthen and protect the teeth. If we find problems, we help parents try to identify what may be the cause of their child’s issues, to keep teeth healthy in the future. If there are cavities, we provide gentle and age-appropriate restorative treatments to keep your child’s teeth healthy and strong.

We love kids and we love giving them happy experiences at the dentist. Dental anxiety is a serious concern for both adults and children, and we believe the best way to prevent anxiety is by taking the time to make sure your children are comfortable with their treatment. We never coerce or force children into situations they are not comfortable with. We also give them plenty of time to get used to what happens during a dental appointment, and make sure they feel empowered to ask questions and communicate their preferences.

Adult Dental Care

As with children, prevention is the key to good oral health. Six-month visits give us the opportunity to remove tartar from the teeth, to prevent the formation of new cavities. They also give us the chance to spot potential problems before they turn into toothaches and major restorations. Even with routine appointments, its easy to develop oral health concerns, such as tooth decay, gingivitis and gum disease. It’s estimated that 99 percent of all adults have experienced some degree of tooth decay; routine visits allow us to treat problems in their earliest stages, before they turn into emergencies.

We also provide a full range of cosmetic dentistry treatments to help our adult patients look their best. As teeth endure years of hard usage, even the most beautiful of smiles may begin to look stained, chipped or misaligned. Cosmetic dentistry can restore the beauty of your smile, for greater confidence and a positive self-image. Whether you seek small improvements or dramatic smile makeovers, we can help you make your smile look new and bright again.

Oral Surgery

If you need a wisdom teeth extraction, dental implant placement or bone grafting, you’ll be glad to know that we provide these treatments in-house. Dr. Hansen performs oral surgery, which means you won’t need to find a separate oral surgeon to get the care you need.

Emergency Treatment

If you’ve ever had a dental emergency, you know that it’s inappropriate to ask a patient to wait several days for an appointment! That’s why we make room for emergencies in our schedule and offer extended hours and Saturday appointments. Whether you are a returning patient or a new patient, we are always welcoming of emergencies. Put our number in your phone right now, as “emergency dentist” and you’ll be glad you did—should you have to deal with an emergency dental problem in the future.

Periodontal Care

Gum disease is a frightening condition that can rob you of your healthy gums (and teeth). Unfortunately, gum disease is also extremely common. There’s a fair chance someone in your family may one day need periodontal treatments. These cleanings can often be traumatic for sensitive gums, so we have invested in laser dentistry tools to provide gentler periodontal cleanings.

 

At Hansen Dentistry of Apex, NC, we want to be your family dentist. Call us at (919) 363-8444 to make an appointment for any children or adults in your family who are due for a check-up.

Tooth Colored Fillings vs Silver Fillings? – Learn More from an Apex Dentist

, by

So you have a tooth that has a cavity and needs a filling. Now what?

Most people know that the two most common options are tooth colored fillings (called composite fillings) and silver fillings (called amalgam fillings).  And most people would agree that the composite fillings are much more aesthetically pleasing than the amalgam fillings.  Some patients prefer not to have amalgam fillings because they contain mercery.  However, it is important to note that ongoing scientific studies conducted over the past 100 years continue to show that amalgam fillings are not harmful.  Sometimes the aesthetic outcome is reason enough to choose a tooth colored filling, especially when the tooth is one that is visible when the patient smiles.

But there are other important reasons that most Apex Dentists these days are choosing to use tooth colored composite fillings rather than amalgam.  And these reasons have to do with the major difference in the way they are placed in the mouth.

Composite fillings are resin-based and are chemically bonded to the tooth.  Amalgams are not.  They are held in place due to a physical retention.  This means that after the dentist removes the decay, he also has to remove additional healthy tooth structure in order to create the proper undercuts and retention grooves to hold the amalgam in place.  This process leaves less remaining tooth structure.

The good thing is that amalgams usually lasts for a really long time.  The bad news is that when they do wear out, they tend to cause larger problems because there is less tooth structure remaining to work with. That is why it is common for a very large amalgam to be replaced with a crown.

If a tooth has a composite filling, the dentist is able to be very conservative in how much tooth structure

he/she removes other than the decay.  This could mean that years later when the composite filling eventually wears out, hopefully another larger composite filling can be placed, rather than a crown.

Another common issue is that teeth with old amalgams tend to develop more cracks.  Because the amalgam filling is not bonded to the tooth, the enamel surrounding the filling is unsupported.  Over time, that unsupported tooth structure microscopically flexes when stress is placed on the tooth.  Years of this flexing can cause cracks to form. These cracks can lead to more extensive (and expensive) treatment, such as a crown,  a root canal, or even loss of the tooth depending on the severity of the fracture.

Whether you have composite or amalgam fillings it is important to maintain your regular cleaning and check-up appointments with your Apex dentist. He/she can keep you informed about the condition of your fillings. That way when one does wear out (and they will, because unfortunately no dental work lasts forever), you can be pro-active, which typically leads to a less expensive and more conservative outcome.
