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.

Some things in life look worse than they really are. A condition known as “geographic tongue” is a good example: while it may look serious, it’s not a cause for real concern.
If you’ve never heard of geographic tongue it’s because it’s not a common ailment: it only affects one to three percent of the population. The name comes from patches of redness on the top surface of the tongue surrounded by grayish white borders, which gives the red patches a look similar to land masses on a map.
It’s known formally as “benign migratory glossitis,” which tells us more about the condition: “benign” means the patches aren’t cancerous; “migratory” indicates the patches tend to move and take different shapes along the surface of the tongue. In fact, it’s possible for them to appear, disappear, and then reappear over the course of a few days.
The exact causes of geographic tongue haven’t been fully substantiated. Researchers believe emotional stress, psychological problems or hormonal disturbances (especially women during pregnancy or ovulation) could be triggers for its occurrence. Certain dietary deficiencies like zinc or vitamin B, or acidic foods are also believed to be factors.
While geographic tongue isn’t painful, it can leave your tongue feeling more sensitive with a mild burning or stinging sensation. If you’re prone to having geographic tongue, there are some things you can do to reduce the irritation. Try to avoid eating acidic or spicy foods like tomatoes, citrus fruits or mint, as well as astringent substances like alcohol or certain mouthwashes. We may also prescribe anesthetic mouthrinses, antihistamines or steroid ointments to help ease any discomfort.
The good news, though, is that this harmless condition is more irritating than anything else. With a little care and forethought you won’t even know you have it.

More than likely your great-grandparents, grandparents and even your parents had a common dental experience: when one of their teeth developed a cavity, their dentist removed the decayed portion (and maybe a little more) through drilling and then filled the cavity. In other words, treatment was mainly reactive—fix the problem when it occurred, then fix it again if it reoccurred.
You may have had similar experiences—but the chances are good your dentist’s approach is now quite different. Today’s tooth decay treatment is much more proactive: address first the issues that cause tooth decay, and if it does occur treat it with an eye on preventing it in the future.
This approach depends on maintaining equilibrium between two sets of competing factors that influence how your teeth may encounter tooth decay. This is known as the caries balance (caries being another name for tooth decay). On one side are factors that increase the risk of decay, known by the acronym BAD: Bad Bacteria that produce acid that dissolves the minerals in tooth enamel; Absence of Saliva, the body’s natural acid neutralizer; and Dietary Habits, especially foods with added sugars that feed bacteria, and acid that further weakens enamel.
There are also factors that decrease the risk of tooth decay, known by the acronym SAFE: Saliva and Sealants, which focuses on methods to boost low salivary flow and cover chewing surfaces prone to decay with sealant materials; Antimicrobials, rinses or other substances that reduce bad bacteria populations and encourage the growth of beneficial strains; Fluoride, increased intake or topical applications of this known enamel-strengthening chemical; and Effective Diet, reducing the amount and frequency of sugary or acidic foods and replacing them with more dental-friendly choices.
In effect, we employ a variety of techniques and materials that inhibit BAD factors and support SAFE ones. The foundation for prevention, though, remains the same as it was for past family generations—practice effective oral hygiene by brushing and flossing daily and regular dental cleanings and checkups to keep bacterial plaque from accumulating and growing. Your own diligent daily care rounds out this more effective way that could change your family history of tooth decay for you and future generations.
