What Forensic Investigators Can Learn From Teeth! | Apex Dentist

, by

If you watch a lot of crime shows like CSI: Miami, you may already know that teeth are often the only body parts that can survive severe types of destruction, like burning. Because of this, forensic scientists often have only teeth to work with when it comes to identifying a victim of a crime or natural/manmade disaster. In today’s post, our Apex dentist explains some of the things forensics investigators (and anthropologists!) can determine by examining dental fragments.

Age at the Time of Death

Teeth can help indicate how old an unknown victim was when he or she died. This is especially easy to do when the victim is a child or adolescent, since baby teeth erupt on a generally universal schedule. The first baby teeth start to emerge during the first two years of life; the first two permanent incisors and the first permanent molar emerge between 6 and 8 years of age; and the majority of the remaining permanent teeth erupt between the ages of 10 and 12 years of age. Wisdom teeth tend to erupt around 18 years of age.

Using dentition to age adult victims is a bit more challenging. Once the wisdom teeth have erupted, age can only be estimated by only morphological changes within the teeth. These changes include tooth root translucency, which increases with age; dental wear on the teeth; and the ratio of amino acids in the teeth (D-aspartic acids convert to L-aspartic acids with age).

Racial Determination

There are very slight differences in the skull structure of different races, which can help assist forensic investigators in identifying victims. People of Asian or Native American descent often have incisors which are shovel-shaped, with ridges on the rear surface of the tooth. People of Caucasian descent tend to have pointier incisors, and smaller teeth overall, often with significant crowding and impacted third molars. Those of African descent rarely have crowding, and the upper teeth often project outwards due to the angled shape of the maxilla. However, these differences are becoming less prevalent, and therefore less useful in identification, as our species becomes less geographically isolated.

Lifestyle & Diet

Teeth hold many clues about an individual’s health issues, even issues that did not originate in the mouth. Tooth loss and erosion of the tooth enamel can be a sign of an eating disorder, or a chronic condition like osteoporosis. Heart disease, skin conditions, blood conditions, and kidney disease can all be identified by examining the teeth. The wear on teeth can also show evidence of what the individual ate and chewed, a detail that is more useful to historic and prehistoric anthropologists.

Individual Dental Characteristics

Forensic dentists can often match victims with specific dental characteristics, like cavity fillings, crown or implant restorations, and orthodontic treatments. If the teeth are damaged by fire, the enamel is often burned off, but post-mortem root canals can still provide clues.

Providing Understanding and Closure

In mass casualty disasters, such as floods, earthquakes, tsunamis, or plane crashes, forensic dentists are enlisted to view the most badly damaged or decomposed remains. Dentists are often be the only ones able to identify the dead, giving them back their names and allowing their families much-needed closure. That’s why, even though it’s unfortunate that these types of situations occur, we should be very grateful for this incredible specialization of dentistry.

Tips for Relieving Dry Mouth, from Our Apex Family Dentist

, by

Occasionally, a patient will visit our office expecting to have no dental cavities, and is very surprised to learn that they have one. Often, this patient is middle-aged or older, brushes and flosses every day, and has no prior history of tooth decay. When this happens, dentists immediately begin to suspect dry mouth caused by new medications or an undiagnosed condition. Dry mouth causes a decrease in saliva production, which is crucial for regulating oral bacteria and keeping the teeth healthy. Below is more information about the causes of dry mouth, and some treatments that can help.

Common Causes of Dry Mouth

Many medications can cause dry mouth as a side effect. Common dry-mouth inducing medications include muscle relaxants; pain medications; antidepressants; blood pressure and heart rhythm medications; Parkinson’s and Alzheimers disease medications; antihistamines; and decongestants. Recreational drug use, chemotherapy, nerve damage due to injury or surgery, and poor nutrition can also cause dry mouth. Note that this list is far from comprehensive; to learn whether a medication, behavior or condition may be causing your dry mouth, consult with your doctor or pharmacist.

Treatments for Dry Mouth

Regardless of the cause of your dry mouth, it’s important to do something about it, as lack of saliva can lead to cavities, gingivitis (gum disease), and halitosis (bad breath). Below are some tips on managing dry mouth from our Apex dentist.

Stay Hydrated

Hydration is important for many aspects of your health in general, but for those suffering from dry mouth, it is even more important. Strive to drink at least 8-12 eight ounce glasses of water a day, unless your doctor advises against it. Taking small sips throughout the day will benefit you more than consuming a large amount in one sitting, as it helps to “wash” your teeth all day long.

Chew Sugarless Gum

Chewing sugarless gum can help to stimulate saliva production, providing your salivary glands are still operational, and not permanently damaged by injury or chemotherapy. The best sugar substitute, from a dentist’s perspective, is xylitol, a plant-derived sweetener that actively kills harmful tooth bacteria. Sucking on sugar-free lollipops can also help boost saliva production.

Avoid Drugs, Alcohol & Citrus 

Alcohol, caffeine, and citric acid can all dry out the mouth and inhibit saliva production. If you use an alcoholic mouthwash, you might want to try switching to a saltwater rinse instead. On the subject of indulgences, tobacco and marijuana can also worsen dry mouth, so if you use these, try to decrease or eliminate your use. Note that the nicotine in electronic cigarettes also contributes to dry mouth.

Add Moisture to Your Environment

Moistening dry foods with broth, sauces, milk or melted butter can make it easier to chew and swallow; you could also simply try adding more non-citric fruit and vegetables to your diet. You can also use a humidifier to add moisture to the ambient air around you, especially while you sleep.

Suffering from Dry Mouth? Talk to an Apex Dentist Today  

As oral healthcare specialists, dentists are able to assess potential causes of dry mouth, and prescribe or recommend products that can treat it. Many moisturizing gels, lozenges, and mouthwashes designed specifically to treat dry mouth are available over the counter; if these prove to be ineffective, your dentist can prescribe medications that stimulate the saliva glands.

Busting 4 of the Most Common Tooth Brushing Myths with Our 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.

Signs You Are Brushing Your Teeth Too Hard from Our Dentist in Apex

, by

Many people believe that plaque is hard to remove, and brush their teeth as hard as they can. However, this can erode your enamel and damage your gum line over time. Here are some signs that you are being too rough on your teeth when you brush.

A Frayed Toothbrush

If your toothbrush looks flat and damaged, with bristles that are split or frayed out, you are probably brushing too vigorously. You can minimize the damage by purchasing an electric toothbrush with a pressure sensor that lights up or stops if you brush too hard. Some electric toothbrushes also come with a 2-minute timer so that you do not brush for too long.

Receding or Bleeding Gums

Bleeding gums are usually a sign of gingivitis, caused by a lack of brushing, but bleeding and receding gums can indicate you are damaging your gum tissue from over-brushing. Gum recession exposes your teeth to infection and decay, so it’s not just a cosmetic issue, but something that needs to be fixed to preserve your overall health. If you suspect your gums are receding, run a finger over your teeth. If you can feel notches or gaps where your gumline used to be, schedule an appointment with a dentist.

Sensitive Teeth

When you over-brush, you wear down the hard enamel protecting your teeth, exposing the sensitive dentin beneath. The more enamel you lose, the more sensitive your teeth will be to hot, cold, and carbonated items, as well as brushing. To preserve the health of your enamel, brush gently, remineralize with fluoride, and avoid toothpastes containing abrasive substances like activated charcoal.

Dull or Yellow Teeth

Yellow teeth can be a result of staining from coffee, wine, and other acidic beverages, but it can also be caused when the white enamel erodes, exposing the naturally yellow dentin beneath. If  your teeth are sensitive and seem to have a yellow sheen, you may be brushing too hard or too often.

Apex Dentist Recommends NOT Using Activated Charcoal Toothpaste

, by

The last time you were browsing Pinterest or Instagram, you might have seen an ad for one of the hippest new health trends: Activated charcoal toothpaste. Made from coal, wood, and other substances, activated charcoal has started popping up as a miracle cure in everything from soap to lotion. But this stuff should never come into contact with your teeth—and here’s why from Dr. Hansen, our Apex NC dentist.

What is activated charcoal?

Activated charcoal is made primarily from coal and wood, but can also contain other burned things, like coconut shells and bones. It becomes “activated” when high temperatures combine with a gas or activating agent to expand its surface area. Traditionally, charcoal has been used to treat poisoning and drug overdoses, as far back as ancient times. When a person ingests activated charcoal, drugs and toxins bind to it, keeping them from being absorbed into the bloodstream. Many people believe that it absorbs other “toxins”, too. 

Why shouldn’t charcoal be used on teeth?

There has been very little evidence of charcoal toothpaste’s safety and effectiveness. In September 2017, the American Dental Association (ADA) published a peer-reviewed scientific literature review stating that researchers found little evidence that charcoal reduces bacteria, prevents cavities, or even reduces tooth stains. Researchers even pointed out some possible carcinogenic ingredients in charcoal and in clay that are found in some of these toothpastes that could be damaging to human health.

What we do know about charcoal toothpaste

While more research might contradict previous studies’ findings, there is something we do know about activated charcoal: it’s extremely abrasive on teeth. That means it can easily damage your enamel, exposing the sensitive dentin beneath. Since dentin is naturally yellow, this means that charcoal toothpaste won’t make your teeth appear white; on the contrary, it will make them look more stained. And once your enamel isn’t protecting your teeth anymore, your cosmetic appearance will be the least of your problems—anything hot, cold, hard, or acidic will be extremely painful! 

Get the best solution for teeth whitening with our Apex cosmetic dentist

If you want to have whiter teeth, the most effective, safe and long-lasting whitening method is using custom whitening trays made by a dentist, or some other professional whitening method. If you use charcoal toothpaste, you might as well brush your teeth with sand—so be sure to book an appointment with our Apex dentist today.

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.

Our Apex NC Dentist Explains the Importance of Annual Dental Checkups

, by

Top Rated Apex NC Dentist

Getting an annual dental checkup is as important as finding a top rated dentist in Apex NC. Herein lies the biggest misconception. Just because a person is looking for a top rated dentist in Apex NC, doesn’t mean that dentist will provide the best care. Finding the right dentist and dental care is not just about finding the best Apex NC family dentist. Finding the best dental care consists of knowing a few things first.

What Makes Our Apex Family Dentist Stand Out?

1) A good family dentist will offer annual dental exams. Having annual dental exams are important. It’s not enough to brush and floss twice day. That part is important, but not all important. The rest lies in the care that the family dentist provides. Dental exams can give all parties involved an overview of what is going on.

2) Another reason for having checkups is a person avoids having future problems with their teeth.. When a person goes in to have a checkup, the dentist can see if there are any issues. If there are, he or she will know how to tackle them the best.

3)If a person waits too long, it could prove detrimental to their mouth and pocket book. This is especially true with the really big treatments.

4) It shows the person knows how to take care of themselves. Those who take proper care of their teeth and gums, will always look attractive and appealing to others. The person will also feel more confident about who they are inside. A persons’ smile can tell a lot about who they are. By skipping this step, a person winds up not feeling to good about themselves.

5) Having regular checkups reduce the chance of gum disease. It’s not just about making sure the teeth are pretty and attractive. One must also look at their gum tissue. Are the gums starting to bleed a little bit? This could be a sign that the person is not taking proper care of their mouth. That is why having annual checkups are so important.

Our Apex Dentists Teach You How to Brush Your Teeth the Proper Way

, by

Our Apex dentists are eager to show you the proper tooth brushing tips in order to prevent gum disease. Most people report some confusion when it comes to tooth brushing tips. Some dentists will recommend one way, while other dentists say something else. There doesn’t seem to be one uniform recommendation for oral health. But as long as you following the tips of our Apex dentists, you will experience a healthier oral hygiene routine in no time.

Split Mouth into Four Groups

Draw an imaginary line down the middle of your two front teeth on the top and bottom of your mouth. You should now have four distinct sections of your mouth: the top left, the bottom left, the top right, and the bottom right. Brush each section thoroughly for 30 seconds. This is how you can be sure that you’re spending enough time with your brushing habits. Many people just don’t brush long enough.

Use Gentle, but Firm Strokes

Don’t grip your toothbrush with a tight fist. Use the same grip you would use for a pencil. All you need is short, gentle strokes to get rid of plaque and prevent gum disease. Applying too much pressure to the brush will irritate your teeth and gums. As long as you brush for two full minutes twice per day, you shouldn’t have to apply a lot of pressure when you brush.

45 Degree Angle

You want to hold the brush at a 45 degree angle when you use it. This is the most effective angle to remove plaque and keep it from building up in your mouth. Use short, horizontal strokes in a circular motion. This can be difficult on the sides and in the back of your mouth. But you should be able to fit the brush into those areas of your mouth enough to get the job done.

Twice Per Day

It can’t be stated enough that you must brush twice per day. It’s easy to get into the routine once you make an effort. You won’t even need to make an effort after a while since it will be automatic. You could set reminders on your phone each morning to tell you to brush your teeth. You need to brush twice per day so that the plaque doesn’t build up too much. Your breath will taste and smell better with regular brushing, and your oral health will improve.

Our Apex Dentist Explains 3 Common Sources for Jaw Pain

, by

Many people experience jaw problems that cause them pain or annoyance and sometimes they may only be temporary, but other times, they may last for weeks, months or even years.

When this happens, patients aren’t always aware of what’s causing their jaw pain, which may be a problem with their TMJ (temper mandibular joint). This joint holds the jaw to the rest of the skull, and when it causes pain and other troubling symptoms, it’s usually a sign of a TMJ disorder.

Naturally, you use your jaw for many aspects of normal day-to-day life, so a TMJ disorder can significantly interfere with it. In order to relieve jaw pain, it’s necessary to first understand the causes, and how a dentist in Apex, like Dr. Rylan Hansen, can help. Here are three common sources for jaw pain.

Malocclusion

A malocclusion is more simply known as an improper bite, and occurs when the teeth do not fit together correctly. This not only causes pain but also inefficient chewing, poor nutrient absorption and an increased risk of tooth breakage. Malocclusions can be caused by a number of factors such as genetics, wisdom teeth impaction, botched dental or orthodontic procedures, thumb-sucking and missing teeth that allow the surrounding ones to shift out of place. To address this issue, you should start by visiting your general dentist. They may place a crown or bridge to help correct small malocclusions. For more significant cases, tooth extraction, braces, or surgery in rare cases may be recommended. Because malocclusions can result from past botched procedures, your dentist may also be able to repair these if they’re the cause.

Tooth Grinding

Grinding your teeth, also known as bruxism, can cause them to become flattened on top. Bruxism most often occurs without the patient’s knowledge while they’re asleep. Otherwise unexplained jaw pain is the most reliable symptom especially if it occurs in the morning, but you may also experience frequent headaches. If you visit your general dentist, they can usually provide you with a special mouth guard to wear at night, thereby protecting your teeth against grinding.

Injury

Any time you sustain an injury to your head, neck or shoulders, there’s a potential for it to cause jaw pain. Injuries like these can damage the jaw joint, tear the muscle tissue, pop the jaw out of alignment or cause chronic inflammation of the area. As a result, patients can experience pain and cracking during eating or talking. Pain from these injuries can often be through one or more methods, including re-alignment, special dental devices, and in some cases, surgery.

Living with chronic jaw pain can make your life miserable. Furthermore, when we are unable to speak or eat without impediment, it complicates effective communication and your ability to keep yourself healthy. If you’ve been struggling to relieve jaw pain, contact our dentist in Apex today to find out what options you have.

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.
