Teeth damaged by decay, periodontal (gum) disease or trauma are often removed (extracted) if they’re deemed beyond repair. But there’s another reason we may recommend an extraction: a tooth is causing or has the potential to cause problems for other teeth and your overall oral health.
Some of the most frequent cases of “preventive extraction” involve the third molars, or wisdom teeth, located in the very back of the mouth. They’re usually the last permanent teeth to come in, which is related to some of the problems they can cause. Because they’re trying to come in among teeth that have already erupted they don’t always erupt properly, often at abnormal angles or not fully erupting through the gums, a condition called impaction.
Impacted or misaligned wisdom teeth can put pressure on adjacent teeth and their roots, which can cause root resorption that damages the second molar. They can also increase the risk of periodontal (gum) disease in the gum tissues of the second molars, which if untreated can ultimately cause teeth and bone loss.
Because of current or possible future problems with wisdom teeth, we often consider removing them at some early point in the person’s dental development. Such a consideration shouldn’t be undertaken lightly, since wisdom teeth extraction is often complex and fraught with complications, and it usually requires a surgical procedure.
That’s why we first conduct a comprehensive examination (including x-ray or other imaging to determine exact location and possible complications) before we recommend an extraction. If after careful analysis an extraction appears to be the best course, we must then consider other factors like planned orthodontics to determine the best time for the procedure.
Once performed, a wisdom tooth extraction can resolve existing problems now and reduce the risks of gum disease or malocclusions in the future. When it comes to wisdom teeth, removing them may be in your or your family member’s best interest for optimal dental health.

Brushing and flossing your teeth provides a lot of benefits, including a brighter smile and fresher breath. But the primary benefit—and ultimate goal—is removing dental plaque. This biofilm of bacteria and food remnants on tooth and gum surfaces is the number one cause for dental disease.
Brushing and flossing can effectively keep plaque under control. Unfortunately, plaque can be a stubborn foe, hiding in areas easily missed if you're not thorough enough.
So how do you know you're doing a good job brushing and flossing? One quick way is to use your tongue or dental floss to feel for any grittiness, a possible sign of remaining plaque. Ultimately, your dentist or hygienist can give you the best evaluation of your hygiene efforts during your three or six-month checkup.
But there's another way to find out more definitively how well you're removing plaque in between dental visits: a plaque disclosing agent. These over-the-counter products contain a dye solution that stains plaque so it stands out from clean tooth surfaces.
A disclosing agent, which can come in the form of tablets, swabs or a liquid, is easy to use. After brushing and flossing, you apply the agent according to the product's directions. The dye reacts with plaque to stain it a distinct color. You may also find products with two-tone dyes that stain older and newer plaque different colors to better gauge your overall effectiveness.
You then examine your teeth in the bathroom mirror, looking especially for patterns of missed plaque. For example, if you see dyed plaque running along the gum line, you'll know you need to concentrate your hygiene there.
After observing what you can do to improve your future efforts, you can then brush and floss your teeth to remove as much of the dyed plaque as you can. The staining from the dye is temporary and any remaining will fade over a few hours.
Using a disclosing agent regularly could help you improve your overall hygiene technique and reduce your risk of disease. Ask your dentist for recommendations on products.

Today’s dental care has advanced leaps and bound over the last century. But these advances are tiny steps compared to what many believe may be coming in the next few decades. This optimism arises from our growing understanding of deoxyribonucleic acid (DNA), the chain-like molecule that houses the genetic instructions for the growth, function and reproduction of every cell in the body.
As researchers unlock the secrets of this vast genetic blueprint unique to each individual the possible applications from this knowledge are astounding. Here are just a few possibilities that could one day impact everyone’s oral health.
Preventing tooth decay. This rampant disease, triggered by bacteria (particularly Streptococcus mutans), can cause extensive damage in otherwise healthy teeth. There’s already some indications from the study of genomics that we may be able to stop or at least hinder this disease in its tracks. Already we’re seeing advances in gene therapy that might be able to inhibit the growth of Strep mutans and reduce its colonies in the mouth.
Growing new teeth. Composed of various layers, a natural tooth is part of a dynamic system of bone and gum ligaments that allow movement, protection and nourishment. Although dental implants are the closest and most advanced artificial approximation we now have to them, implants still can’t fully measure up to the function and capabilities of a natural tooth. But further insight into the genetic code may one day allow us to reproduce a living replacement tooth for a lost one.
Harnessing saliva for detecting disease. The impact of genomics related to the mouth could impact more than just the mouth itself. Researchers have discovered that saliva contains genetic information similar to blood, urine and other bodily fluids with markers for various disease conditions. Unlike other fluids, though, saliva is relatively easy to collect. The key is new equipment and testing protocols to take advantage of the information already available in a single drop of saliva.
These examples illustrate the range of possibilities for better health in the future: a reduction in dental disease early in life; new and better ways to restore missing teeth; and quicker ways to diagnose dangerous health conditions.
