Via a recent Instagram post, pop diva Ariana Grande became the latest young celebrity to publicly acknowledge a dental milestone: having her wisdom teeth removed. The singer of hits such as “Break Free” and “Problem” posted an after-surgery picture of herself (wearing her signature cat-eye eyeliner), with a caption addressed to her teeth: “Peace out, final three wisdom teeth. It’s been real.”
With the post, Grande joined several other celebs (including Lily Allen, Paris Hilton and Emile Hirsch) who have shared their dental surgery experience with fans. Will "wisdom teeth removal" become a new trending topic on social media? We aren’t sure — but we can explain a bit about the procedure, and why many younger adults may need it.
Technically called the “third molars,” wisdom teeth usually begin to emerge from the gums between the ages of 17 and 25 — presumably, around the same time that a certain amount of wisdom emerges. Most people have four of these big molars, which are located all the way in the back of the mouth, on the left and right sides of the upper and lower jaws.
But when wisdom teeth begin to appear, there’s often a problem: Many people don’t have enough space in their jaws to accommodate them. When these molars lack sufficient space to fully erupt (emerge), they are said to be “impacted.” Impacted teeth can cause a number of serious problems: These may include pain, an increased potential for bacterial infections, periodontal disease, and even the formation of cysts (pockets of infection below the gum line), which can eventually lead to tooth and bone loss.
In most cases, the best treatment for impacted wisdom teeth is extraction (removal) of the problem teeth. Wisdom tooth extraction is a routine, in-office procedure that is usually performed under local anesthesia or “conscious sedation,” a type of anesthesia where the patient remains conscious (able to breathe normally and respond to stimuli), but is free from any pain or distress. Anti-anxiety medications may also be given, especially for those who are apprehensive about dental procedures.
So if you find you need your wisdom teeth extracted, don’t be afraid to “Break Free” like Ariana Grande did; whether you post the results on social media is entirely up to you. If you would like more information about wisdom tooth extraction, please call our office to schedule a consultation.

Over the last century and a half millions of people have had a tooth cavity filled with “silver” amalgam. Perhaps you’re one of them. The use of this effective and durable filling has declined in recent years, but only because of the development of more attractive tooth-colored materials.
At the same time there’s another issue that’s been brewing in recent years about this otherwise dependable metal alloy: the inclusion of mercury in amalgam, about half of its starting mixture. Various studies have shown mercury exposure can have a cumulative toxic effect on humans. As a result, you may already be heeding warnings to limit certain seafood in your diet.
So, should you be equally concerned about amalgam fillings — even going so far as to have any existing ones removed?
Before taking such a drastic step, let’s look at the facts. To begin with, not all forms of mercury are equally toxic. The form causing the most concern is called methylmercury, a compound formed when mercury released in the environment combines with organic molecules. This is the form certain large fish like salmon and tuna ingest, which we then ingest when we eat them. Methylmercury can accumulate in the body’s tissues where at high levels it can damage various organ systems.
Dental amalgam, on the other hand, uses elemental mercury. Dentists take it in liquid form and mix it with a powder of other metals like silver, tin and copper to create a pliable paste. After it’s placed in a prepared cavity, the amalgam hardens into a compound in which the mercury interlaces with the other metals and becomes “trapped.”
Although over time the filling may emit trace amounts of mercury vapor, it’s well below harmful levels. You’re more likely to encounter “un-trapped” mercury in your diet than from a dental filling. And scores of studies over amalgam’s 150-year history have produced no demonstrable ill effects due to mercury.
Although it now competes with more attractive materials, amalgam still fills (no pun intended) a necessary role. Dentists frequently use amalgam in less visible back teeth, which encounter higher chewing pressures than front teeth. So, if you already have an amalgam filling or we recommend one to you, relax — you’re really in no danger of mercury poisoning.
