As permanent teeth gradually replace primary (“baby”) teeth, most will come in by early adolescence. But the back third molars—the wisdom teeth—are often the last to the party, usually erupting between ages 18 and 24, and the source of possible problems.
This is because the wisdom teeth often erupt on an already crowded jaw populated by other teeth. As a result, they can be impacted, meaning they may erupt partially or not at all and remain largely below the gum surface.
An impacted tooth can impinge on its neighboring teeth and damage their roots or disrupt their protective gum attachment, all of which makes them more susceptible to tooth decay or periodontal (gum) disease. Impacted teeth can also foster the formation of infected cysts that create areas of bone loss or painful infections in the gums of other teeth.
Even when symptoms like these aren’t present, many dentists recommend removing the wisdom teeth as a preemptive measure against future problems or disease. This often requires a surgical extraction: in fact, wisdom teeth removal is the most common oral surgical procedure.
But now there’s a growing consensus among dentists that removing or not removing wisdom teeth should depend on an individual’s unique circumstances. Patients who are having adverse oral health effects from impacted wisdom teeth should consider removing them, especially if they’ve already encountered dental disease. But the extraction decision isn’t as easy for patients with no current signs of either impaction or disease. That doesn’t mean their situation won’t change in the future.
One way to manage all these potentialities is a strategy called active surveillance. With this approach, patient and dentist keep a close eye on wisdom teeth development and possible signs of impaction or disease. Most dentists recommend carefully examining the wisdom teeth (including diagnostic x-rays and other imaging) every 24 months.
Following this strategy doesn’t mean the patient won’t eventually have their wisdom teeth removed, but not until there are clearer signs of trouble. But whatever the outcome might be, dealing properly with wisdom teeth is a high priority for preventing future oral health problems.

The Internet is truly amazing: It takes only a few seconds to tap into a vast store of knowledge to find information that once took people hours or days. But amidst all that helpful data, there's also some not so helpful information—in fact, some can be downright harmful, including to your dental health.
One particular Internet trend is brushing teeth with black, gooey substances containing activated charcoal. Scores of online videos featuring people doing this are getting viral views, perhaps more for the “gross” factor than the claimed health benefits.
So, why do it? Advocates of using activated charcoal for oral hygiene claim the ingredient kills harmful microorganisms in your mouth. The charcoal is also supposed to whiten your teeth.
But clinical studies of the practice, including one recently published in the Journal of the American Dental Association have been unable to substantiate these claims. There's simply no evidence that activated charcoal does what its advocates say it can do.
Unfortunately, there is evidence the practice can actually harm your teeth. This is because activated charcoal is an abrasive substance that over time could damage your teeth's enamel. Eroded enamel doesn't regrow, so eventually the more vulnerable dentin, the tooth layer just beneath the protective enamel, becomes exposed. It's not only darker and less attractive than enamel, its more susceptible to tooth decay and cavities.
The best way to care for your teeth, brushing and flossing daily, may seem boring compared to videos of brushing with charcoal, but it is effective—and safe. You should also see your dentist for more thorough cleanings at least every six months to round out your dental care.
And if you want a brighter smile, your dentist can perform a tooth whitening procedure that can give you months or even years of satisfaction. Professional tooth whitening (or even home whitening kits applied properly) also won't harm your enamel.
Surgical tooth extraction is a fairly routine procedure with few complications. But one rare complication called dry socket does affect a small number of patients. Dry socket, which derives its name from its appearance, can be quite painful. Fortunately, though, it doesn't pose a danger to oral health.
Normally after a surgical extraction, a blood clot forms in the empty socket. This is nature's way of protecting the underlying bone and nerves from various stimuli in the mouth as well as protecting the area. Sometimes, though, the clot fails to form or only forms partially (almost exclusively in lower wisdom teeth), exposing the sensitive tissues beneath the socket.
Patients begin to notice the painful effects from a dry socket about three or four days after surgery, which then can persist for one to three more days. Besides dull or throbbing pain, people may also experience a foul odor or taste in their mouth.
People who smoke, women taking oral contraceptives or those performing any activity that puts pressure on the surgical site are more likely to develop dry socket. Of the latter, one of the most common ways to develop dry socket is vigorous brushing of the site too soon after surgery, which can damage a forming blood clot.
Surgeons do take steps to reduce the likelihood of a dry socket by minimizing trauma to the site during surgery, avoiding bacterial contamination and suturing the area. You can also decrease your chances of developing a dry socket by avoiding the following for the first day or so after surgery:
- brushing the surgical area (if advised by your surgeon);
- rinsing too aggressively;
- drinking through a straw or consuming hot liquid;
If a dry socket does develop, see your dentist as soon as possible. Dentists can treat the site with a medicated dressing and relieve the pain substantially. The dressing will need to be changed every few days until the pain has decreased significantly, and then left in place to facilitate faster healing.
While dry sockets do heal and won't permanently damage the area, it can be quite uncomfortable while it lasts. Taking precautions can prevent it—and seeing a dentist promptly if it occurs can greatly reduce your discomfort.
