Each part of the human body is an intricate wonder. Take your teeth, for example: they’re so woven into everyday life we don’t notice them, yet they each work seamlessly with the jaws and mouth so we can eat, speak and even smile.
Here, then, are a few facts to help you understand — and appreciate — these tiny, amazing wonders we call teeth.
Layer Upon Layer. Rather than one solid mass, teeth are composed of different layers of slightly different tissues each with a unique role in protecting and enabling a tooth to function. Innermost is the pulp filled with connective tissue encasing blood vessels and nerves that transmit sensations to the brain. The next layer out is the dentin, a bone-like material sensitive to touch and other stimuli, which also absorbs some of the forces generated when biting or chewing. The outermost layer is enamel, the hardest material in the body and the tooth’s first defense against infection and other dangers.
Front and Center. Teeth perform different functions depending on their type and location. Front teeth are our “onstage performers” — they help us to speak and enunciate words clearly and, of course, contribute to our smile. They’re also adept at cutting through food when it first enters our mouths.
The Support Team. In keeping with our theater analogy, back teeth are our “backstage crew”: they help support our facial height, provide balance for the jaws as we swallow and protect the front teeth from too much vertical force. They’re also able to crush food before we finally swallow, which aids in the digestive process.
Intended for a Lifetime. If you consider all the environmental factors our teeth face — acidic foods, biting forces and temperature swings to name a few — you then can appreciate their resiliency. Of course, teeth have their enemies: decay, infection and trauma. With daily brushing and flossing and at least a couple of visits a year to our office for cleanings and checkups, you can help thwart many of those enemies. With both our efforts we can make sure your teeth really do last a lifetime.
You brush and floss every day to rid your teeth and gums of disease-causing plaque. But while “showing up” is most of the battle, the effectiveness of your technique will win the war.
So, how good are you at removing plaque? One quick way to find out is the “tongue test”—simply rub your tongue along your teeth: they should feel smooth and “squeaky” clean. Surfaces that feel rough and gritty probably still contain plaque.
For a more thorough evaluation, your dental hygienist may use a product during your regular dental visit called a plaque disclosing agent. It’s a solution applied to your teeth that dyes any bacterial plaque present on tooth surfaces a certain color while leaving clean surfaces un-dyed. The disclosing agent shows you where you’re effectively removing plaque and where you’re not.
These products aren’t exclusive to the dental office—you can use something similar at home if you’d like to know how well you’re doing with your hygiene before your next visit. You can find them over-the-counter as tablets, swabs or solutions. You may even find some that have two dye colors, one that reveals older plaque deposits and the other newer plaque.
You simply follow the product’s directions by first brushing and flossing as usual, then chewing the tablet, daubing the swab on all tooth and gum surfaces, or swishing the solution in your mouth like mouthwash for about 30 seconds before spitting it out. You can then use a mirror to observe any dye staining. Pay attention to patterns: for example, dyed plaque scalloping along the gum line means you’ll need to work your brush a little more in those areas.
The dye could color your gums, lips and tongue as well as your teeth, but it only lasts a few hours. And while plaque disclosing agents are FDA-approved for oral use, you should still check the ingredients for any to which you may be allergic.
All in all, a plaque disclosing agent is a good way to occasionally check the effectiveness of your plaque removal efforts. By improving your technique you may further lower your risk of dental disease.

Tooth sensitivity can be disheartening: you’re always on your guard with what you eat or drink, and perhaps you’ve even given up on favorite foods or beverages.
The most common cause for this painful sensitivity is dentin exposure caused by receding gums. Dentin contains tiny open structures called tubules that transmit changes in temperature or pressure to the nerves in the pulp, which in turn signal pain to the brain. The enamel that covers the dentin, along with the gum tissues, creates a barrier between the environment and dentin to prevent it from becoming over-stimulated.
Due to such causes as aggressive over-brushing or periodontal (gum) disease, the gum tissues can recede from the teeth. This exposes portions of the dentin not covered by enamel to the effects of hot or cold. The result is an over-stimulation of the dentin when encountering normal environmental conditions.
So, what can be done to relieve painful tooth sensitivity? Here are 3 ways to stop or minimize the symptoms.
Change your brushing habits. As mentioned, brushing too hard and/or too often can contribute to gum recession. The whole purpose of brushing (and flossing) is to remove bacterial plaque that’s built up on tooth surfaces; a gentle action with a soft brush is sufficient. Anything more than two brushings a day is usually too much — you should also avoid brushing just after consuming acidic foods or liquids to give saliva time to neutralize acid and restore minerals to the enamel.
Include fluoride in your dental care. Fluoride has been proven to strengthen enamel. Be sure, then, to use toothpastes and other hygiene products that contain fluoride. With severe sensitivity you may also benefit from a fluoride varnish applied by a dentist to your teeth that not only strengthens enamel but also provides a barrier to exposed dentin.
Seek treatment for dental disease. Tooth sensitivity is often linked to tooth decay or periodontal (gum) disease. Treating dental disease may include plaque removal, gum surgery to restore receded gums, a filling to remove decay or root canal therapy when the decay gets to the tooth pulp. These treatments could all have an effect on reducing or ending your tooth sensitivity.

Your teeth’s hard, enamel coating protects them from environmental dangers or disease. But although it’s made of the hardest substance in the human body, enamel isn’t invincible — prolonged exposure to acid can cause dental erosion, a condition in which the enamel’s mineral content permanently dissolves, a process known as de-mineralization.
De-mineralization occurs anytime our mouth environment becomes too acidic due to eating or drinking items with high acid content. Saliva normally neutralizes mouth acid in thirty minutes to an hour after we eat, as well as restores mineral content to the enamel (re-mineralization). Danger arises, though, if the saliva’s buffering action is overwhelmed by chronic acidity, caused mainly by constant snacking or sipping on acidic foods and beverages throughout the day — in this situation, saliva can’t complete the process of buffering and re-mineralization.
As a result, the enamel may permanently lose its mineral content and strength over time. This permanent dental erosion leads to serious consequences: the teeth become more susceptible to decay; the dentin becomes exposed, which causes pain and sensitivity to pressure and temperature changes; and changes in the teeth’s size and color can negatively alter your appearance.
It’s important to take action then before dental erosion occurs. Along with daily oral hygiene, restrict your consumption of acidic foods and beverages to meal times and cut back on between-meal snacks. Rather than a sports drink after exercising, drink nature’s hydrator — water. You should also alter your brushing habits slightly — rather than brush right after you eat, wait thirty minutes to an hour. This gives saliva time to restore the mouth to its normal pH and re-mineralize the enamel. Brushing right after can remove even more of the minerals in softened enamel.
If significant erosion has occurred, there are a number of treatment options we can undertake to preserve remaining tooth structure and enhance your appearance. In moderate cases, we can reshape and cover damaged teeth using dental materials like composite resins or porcelain to fill decayed areas or cover teeth with veneers or crowns.
The key of course, is to identify dental erosion through clinical examination as soon as possible to minimize damage. Your enamel plays a critical role in protecting your teeth from disease — so take the right steps to protect your enamel.

Not coincidentally, GERD Awareness Week overlaps with the Thanksgiving holiday. Many people get acid indigestion from time to time, especially during this month of major feasting, but if you suffer from more than occasional acid reflux, you may be among the 20 percent of U.S. adults with gastroesophageal reflux disease, or GERD. For many individuals, painful heartburn often accompanies acid reflux; however, for others there are few or no symptoms. In the latter situation, dentists may be the first to suspect GERD based on what we see during a regular dental exam.
With GERD, acid washes up from the stomach into the esophagus or throat, and even into the mouth. If the condition is not treated, the repeated contact with acid can lead to ulcers and cause pre-cancerous cell changes along the esophagus lining. In addition, the acids can eat away at tooth enamel and harm the soft tissues of the mouth, which may result in severely eroded teeth and chronic gum disease. Unfortunately for those who have relatively minor symptoms, GERD may go undetected until serious damage has been done. For this reason, diagnosis and treatment of GERD is very important.
You can play a big role in managing your GERD symptoms. Besides taking any over-the-counter or prescription medication your doctor recommends, you can help control acid reflux by eating smaller meals, avoiding foods and beverages that trigger heartburn, refraining from eating within three hours of bedtime, and resisting the urge to recline right after eating. Also, quitting smoking and taking off extra weight can help greatly.
Further, it is important to take steps to protect your teeth if you suffer from GERD. Here are some tips:
- Neutralize acid by chewing on an antacid tablet or rinsing your mouth with half a teaspoon of baking soda mixed into a cup of water.
- Don't brush your teeth immediately after an episode of acid reflux, as this could damage the weakened tooth enamel. Instead, rinse your mouth with water to dilute the acid and wait an hour before you brush to allow your saliva to rebuild the minerals on the surface of your teeth.
- Schedule regular dental visits to monitor the health of your teeth and gums. Depending on your specific situation, we may recommend a particular treatment to help strengthen your teeth.
Our goal is to help you preserve your teeth for life, so be sure to tell us if you have been diagnosed with GERD or any other medical condition. If you have questions, contact us or schedule an appointment for a consultation.
