Tooth-Colored Fillings vs. Silver Fillings: Which Should I Choose? Ask 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.

What’s the Difference Between Plaque and Tartar? Ask a Dentist in Apex

, by

WE OFTEN GET THIS QUESTION from our patients, “What’s the difference between plaque and tartar?” Many patients think they are the same thing. However, there is an important difference between the two.  Understanding how they are different can help explain why a daily oral hygiene routine is so crucial, as well as twice-yearly visits to your dentist.

plaque
What Is Plaque?

Dental plaque is the soft, sticky film that builds up on your teeth and under your gums. It starts forming soon after you finish brushing. In other words, plaque is constantly accumulating on your teeth. And guess what? It contains millions of bacteria! When you eat—especially carbohydrates or sugar—you’re not the only one getting a meal…so are the bacteria on your teeth. After these bacteria dine on sugar, they produce acids that erode your tooth enamel and cause cavities.

That’s why good daily oral hygiene is essential to preventing tooth decay and protecting your smile from the bacteria in plaque. To prevent plaque buildup, remember to brush at least twice a day and floss once a day. Drinking water and chewing sugar-free gum after meals and snacks can also help!

What Is Tartar?

So if that’s plaque, what’s tartar? Tartar is what accumulates on your teeth when plaque is not removed. If plaque is left on your teeth for too long, it will harden into tartar and is much more difficult to remove. In fact, tartar can only be removed by a dental professional–you can’t get rid of it with regular brushing and flossing. Tartar removal is one of the reasons that visiting your dentist every six months is so important!

Plaque buildup that hardens into tartar can cause more than just cavities. It can cause tooth discoloration and sensitivity as well as gum recession and periodontal disease. To reduce plaque buildup and tartar from forming, make sure you are brushing and flossing daily.

Come And See Us Every Six Months

No matter how great your oral hygiene is, plaque and tartar formation are inevitable. So come in to see us every six months! Our job is to help you maintain a beautiful, healthy smile that’s plaque- and tarter-free!

Do Wisdom Teeth Need to be Extracted? Ask an Apex Oral Surgeon

, by

We have found that while many of our patients with wisdom teeth know that they should be extracted, very few of them understand why.

So here you go…A Little Wisdom about Wisdom Teeth.

There are several reasons your Apex Dentist might recommend having your third molars, also known as Wisdom teeth, extracted.   Very few people have adequate space in their dental arch for wisdom teeth.  If you are one of the lucky ones that does have enough room, be sure your toothbrush is reaching all the way back to those teeth, as they are often very difficult to keep clean.  If/when 3rd molars develop cavities (as they often do), it is usually better to put financial resources towards having these teeth extracted rather than filled as they usually only cause more problems down the road.

dental-arch

For patients who do not have enough room in their dental arch, the 3rd molars are often unable to properly erupt, making it difficult or even impossible to keep clean.  The improper eruption can cause a variety of problems including but not limited to, periodontal infections, dental decay, and dental abcesses.

The first radiograph was of a patient for whom Dr. Hansen had to perform an extraction not only the partially erupted  wisdom tooth but the 2nd (more important) molar as well due to the decay caused by the wisdom tooth.

radiograph

The second radiograph demonstrates another reason that 3rd molars often need to be extracted:  dental abcesses.  This particular abcess was so large that this patient was a risk of her lower jaw breaking. The radiograph also demonstrates the importance of routine dental check ups, as this patient did not have any pain associated with the dental abcess.   She literally would not have ever known that it was there except that she was consistent with her dental examinations, including dental radiographs.

Understanding dental problems that can arise from  wisdom teeth is important so patients are able to take necessary steps to seek treatment. Typically, your Apex dentist will recommend having wisdom extracted between ages 15 and 25 because healing and recovery is much easier for younger patients.

If only our wisdom teeth made us all-knowing and wise…that would make for a good case in keeping them!

Everything You Need to Know About Dental Sealants from a Family Dentist in Apex

, by

What is a sealant?  

A sealant is a tooth-colored resin material that is placed on chewing surfaces of teeth to help them stay cavity-free.

crack

Why do teeth need sealants?

Molar and premolar teeth often have very deep pits and fissures.  While bacteria can easily enters these groves, toothbrush bristles are often too large and therefore ineffective.  As a result, these areas become the perfect breeding ground for bacteria to multiply which can lead to dental decay. A sealant does just what its name suggests…it seals off the grooves so that bacteria can’t enter.  After a sealant is placed these areas can no longer harbor bacteria and your tooth brushing once again becomes effective.

tooth-groove

What teeth need sealants? 

Any teeth that have deep groves or pits can benefit from sealants.  These are most often found on molar and premolar (teeth right in front of the molars) permanent teeth, but varies from one individual to another.  One person might benefit from sealants on all molars and premolars (16 teeth), while another may only need their molars (8 teeth) sealed.

Once a tooth has a dental filling in it, it no longer benefits from a sealant.

People often think that only children benefit from sealants.  That is because sealants are typically placed on a child’s molars when they first erupt.  The reality is that any teeth with deep pits and fissures (that do not already have fillings) can benefit from sealants because they  will help prevent future cavities.

How is a sealant applied?

No tooth structure is removed in order to place a sealant.  Instead it is kind of like painting your fingernails: resin material is only added, nothing is taken away.  The tooth is thoroughly cleaned with a pumice and etch.  The tooth is then washed thoroughly. Finally, the sealant material is applied and then cured with a light in order to harden it.

before-after-sealantHow long do sealants lasts?

Sealants typically last two to five years.  Although, it is not uncommon to see sealants in adults that were placed in childhood and are still intact.

Avoiding sticky, chewy, and hard foods can potentially prolong the life of a sealant.

If a sealant is no longer fully intact then it is no longer effective and should be replaced by your dentist.  If it has been less than two years since the sealant was placed, ask if your Apex family dentist offers a warranty for sealants.

Our Apex Dentist Explains The Importance of Replacing Missing Teeth

, by

Everyday we see patients that have missing teeth. Sometimes they are teeth that have been recently extracted.  Other times they have been missing for years.  The reasons for why the teeth are missing vary.  But the answers about why to replace them are usually the same.  So we wanted to share these answers with you!

In the US, about 70% of the population is missing one or more teeth.  Tooth loss can lead to reduced self confidence because of gaps in a person’s smile.  Unfortunately, effects on physical appearance are not the only result.

 

Teeth are lost or missing for several reasons such as trauma, decay, periodontal disease, or even genetics.  It is important to replace missing teeth because when a tooth is missing there is no contact with the opposing arch.  This can cause opposing teeth to gradually extrude which leads to other problem, such as fractures, mobility, tooth loss, shifting in surrounding teeth, and gum problems.

There is more than one option available to patients for replacing missing teeth.  Like most choices, each option has pros and cons.  The 3 most common options are replacing the missing teeth with implants, crowns and bridges or dentures. Sometimes a combination of two of these options can be used, such as a denture that is supported by implants, or a bridge that is supported by implants.  We will cover more about what the pros and cons of each of these treatments are in upcoming blog posts.

“An ounce of prevention is worth a pound of cure”, so whenever possible try to avoid loosing the tooth in the first place.  The financial cost of saving a tooth with a crown or even a crown and a root canal is substantially less than the cost of an implant and crown or a bridge.  Not to mention that by saving one tooth, you are also helping keep the surrounding ones healthy as well.

The loss of a tooth is not always preventable, such as in the case of trauma or when a tooth is congenitally missing.  But no matter the cause, it is important to understand the effects of missing teeth so that you can take the necessary steps to prevent further problems. Your Apex dentist can answer questions you have about what treatment best fits your needs and your smile.  And check back here when we explain more about each treatment in the upcoming weeks!

Our Apex Dentist Explains Why Overbites are More Than a Cosmetic Issue

, by

More than a cosmetic issue: How malocclusions harm your teeth

If you have been to the dentist lately, you may have learned that you have a malocclusion—in layman’s terms, an overbite, underbite, crossbite, or other type of situation that prevents the upper and lower teeth from aligning correctly. While many people believe that their underbite or overbite is simply a cosmetic issue, malocclusions affect far more than your appearance. Below are some ways dental malocclusions harm your teeth.

Tooth decay

There are three categories of malocclusion. In Class I, the teeth may be rotated, crowded, or too spaced-out for the upper and lower jaw to meet properly. It’s that second issue, overcrowding, that can lead to tooth decay. Because crowded teeth are much more difficult to clean properly, patients may struggle with oral hygiene despite their best efforts. Flossing can be challenging if teeth are grouped too tightly, and brushing might not reach all the hiding places where bacteria live. Therefore, fixing crowded teeth isn’t just a matter of having a pretty smile; it’s actually a matter of preserving your long-term oral health.

Worn tooth enamel 

If your teeth are not properly aligned, or if some teeth jut out higher than the others, they will get worn down over time from normal talking and chewing. This is problematic because your enamel protects the sensitive dentin beneath it, and once it’s gone, your teeth will be more susceptible to cavities and bacteria (not to mention, a lot of pain and discomfort.) Re-aligning your teeth into their correct positions helps ensure long-term protection (and no painful, expensive procedures in the future!)

Jaw pain (TMJ)

The human jaw has evolved to operate based on one type of tooth arrangement. Uneven teeth can impact the muscles of the jaw, causing long-term problems usually referred to as TMJ, or Temporomandibular joint (TMJ) syndrome. This condition is characterized a pain in the jaw joint; head and neck pain; facial pain; ear pain; frequent headaches; a jaw that is locked in position or difficult to open; problems with biting; and jaw clicking or popping sounds when the patient bites. While you might not develop severe TMJ from a misaligned jaw, you are certainly at risk for it, and it is probable you will develop at least one of the symptoms, such as jaw clicking or headaches.

Speech impediments 

The shape of our mouths is critical when it comes to forming words and communicating. Malocclusion can lead to speech problems, especially for young children just getting a grasp on language. Speech problems can have a significant impact on an individuals self-esteem, social interactions, and job or school performance—so it’s not a minor thing! If your teeth are interfering with the way you communicate, it’s important to have them corrected.

Avoid these issues with our Apex Dentist today! 

As much as Dr. Hansen and the rest of the team at Hansen Dentistry want you to have a beautiful smile that looks great in pictures, we are much more concerned about preserving your long-term oral health! Correcting crooked, misaligned, or gapping teeth is primarily about keeping your teeth strong and cavity-free over the course of your lifetime. One of the easiest ways to do this is by using Invisalign trays to move the teeth into alignment. To learn more about how Invisalign can help you, call us now for a consultation!

What is Bottle Rot? Apex Dentist Explains How to Prevent Infant Tooth Decay

, by

Also known as baby bottle tooth decay, bottle rot occurs when a baby’s teeth are exposed to sugar for so long that they begin to develop cavities. Below is more information about bottle rot, and what you can do to prevent it.

Consequences of Cavities in Baby Teeth

Some people believe that it doesn’t matter if a baby or small child has cavities, because the baby teeth will eventually fall out, to be replaced by permanent adult teeth. However, cavities cause harm to children for several reasons. Firstly, the bacteria in the teeth can spread to the rest of the body, causing other health problems. And secondly, healthy baby teeth are necessary to ensure that the permanent teeth grow in correctly. That is why it’s important to keep up with your infant’s oral care.

How to Prevent Bottle Rot

Bottle rot mainly occurs when parents fill a baby bottle with a sweet beverage to keep their child calm and happy. Another mistake is putting the baby to bed with a bottle, which exposes the child’s delicate teeth to sugar for an extended period of time. When teeth are exposed to sugar for too long, bacteria that live in the mouth consume it and convert it into acid, which destroys the enamel. Therefore, it’s important to limit your child’s exposure to sugary drinks as much as possible.

Should I Brush My Baby’s Teeth?

Yes! You can “brush” a baby’s teeth by simply wiping the gums with a washcloth after each meal and before bed. Once the baby has grown teeth, you can use a baby toothbrush and a rice-sized amount of toothpaste to keep them clean. This not only removes bacteria and debris, but establishes a healthy habit early! You can also limit oral bacteria by regularly sterilizing your baby’s bottle with soap and hot water.

Limiting Sugar Intake

As we said above, you should never put your child to bed with a bottle of juice. It’s also a good idea to limit the juice during the day, as most juice brands tend to be high-sugar. Formula, breast milk, and water should be fine. If your toddler really likes juice and is old enough to be vocal about it, try diluting it with water. Most kids won’t be able to tell the difference. Finally, avoid dipping a pacifier into honey or sugar.

Yes, Your Baby Can See the Dentist!

Generally, you can start taking your baby to the dentist as soon as you notice the first tooth erupting. Dental checkups for infants are mainly a time to talk about the health of your baby’s teeth, as well as steps that you can take to avoid problems like bottle rot. Plus, you can discuss options like sealant coatings that are used as a preventative measure against tooth decay.

Bottle rot doesn’t have to be a problem that you encounter while raising your baby. With some simple strategies, your child’s teeth will grow in perfectly and remain clean and strong.

Should I Get an Electric Toothbrush? Ask an Apex Cosmetic Dentistry

, by

In a word—yes! An electric toothbrush does the hard work for you, removing much more plaque than a traditional, manual toothbrush. And with so many different types and features available, it’s easy to find an electric toothbrush that suits your specific oral health needs. In today’s blog, our Apex dentist explains some reasons why you should consider buying an electric toothbrush.

Easier to Use

To use an electric toothbrush, you only need only guide it along the surfaces of your teeth. This is much easier than scrubbing back and forth, and many people with arthritis or similar conditions find using a power toothbrush less painful to use. Electric toothbrushes may also help children brush their teeth more effectively.

Better Plaque Removal

Multiple independent studies have shown that electric toothbrushes remove more plaque and reduce gingivitis more effectively than manual brushes, in both the short and long term. Results are especially positive with brushes that have a rotating, oscillating action.

Superior Technology and Features

Some electric toothbrushes are even able to help you improve your brushing habits. Hi-tech toothbrush features may include:

  • Various brushing modes designed for sensitive teeth, whitening, or gum-massaging
  • Pressure sensors which gently signal when you’re brushing too hard
  • Timers which help you keep track of how long you’re brushing each quadrant of your mouth
  • Digital reminders that it’s time to replace your brush head
  • Multiple brush head compatibility, so you can choose which kind of bristle design you prefer

We encourage all our clients to consider switching to an electric toothbrush, because we almost always see a remarkable improvement in the oral hygiene of patients who do. If you would like a recommendation for a particular style or brand, just ask us during your next dental cleaning, and we will be happy to help!

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.

Teeth and Sugar: Dispelling the Top 5 Dental Myths with our Dentist in Apex NC

, by

Teeth and Sugar: Dispelling the Top 5 Dental Myths

You’ve heard it since you were a small child: the #1 greatest threat to your teeth is sugar. Turns out, though, there are other things that damage our teeth just as much, and cutting out sugar isn’t always enough to guarantee total tooth health. Here are some of the most common misconceptions people have when it comes to sugar, teeth, and cavities.

Misconception 1: Sipping on one soda throughout the morning isn’t as dangerous as, say, eating 4 frosted donuts in one sitting.  

The truth: It’s actually much worse to expose your teeth to small amounts of sugar throughout the day, than to eat a high-sugar item in one go. It’s the frequency of sugar consumption that damages your teeth, not the amount. If you ate an entire tub of icing in a minute, we’re not saying it would do your body any favors; but your teeth would likely be fine, as the icing would only touch them for 60 seconds or so. Spending four hours working your way through a coke, however, exposes your teeth to an almost constant wash of acid.

Misconception 2: Sugar is bad for my teeth, but carbs aren’t. If I switch to unfrosted mini-wheats for breakfast, my teeth will be fine.

The truth: Simple carbohydrates are actually just as bad for teeth as sugar. That’s because it isn’t really sugar or carbs which are the culprits for cavities; those just happen to be the favorite foods of the bacteria that live in your mouth. Bacteria just love carbs and sugar, and once they’re done chowing down, they convert it into lactic acid, the stuff that erodes your teeth and creates cavities. Therefore, eating a bowl of crackers at your desk hurts your teeth as much as eating a bowl of candy.

Misconception 3: Drinking my coffee black might stain my teeth, but it won’t hurt the enamel.  

The truth: Drinking your coffee black will still damage your teeth, because it is extremely high in acid. Remember that the bacteria in your mouth eat the sugar and then convert it into acid. Black coffee by itself already is an acid, so nixing the sugar isn’t making things much better. (If you can’t kick your coffee habit, drinking it through a straw can help save your teeth from damage and staining.)

Misconception 4: Drinking sugar-free soda, or soda alternatives like LaCroix, will not hurt my teeth.

The truth: Carbonation can badly damage your enamel. Soda water’s pH is around 3 or 4, depending on the brand, making it around 100 to 1000 times more acidic than water. With that said, drinking soda water is better than drinking straight soda, and is often a good middle step to eventually going totally soda-free.
