As Spring turns to Summer, millions of students will depart high school in the time-honored rite of passage called graduation. At the same time, quite a few of these graduates will be experiencing another maturity milestone: the eruption (coming in) of their last permanent teeth.
Typically, these are the back third molars, better known as “wisdom teeth,” emerging on either end of both the top and bottom jaws sometime between the ages of 18 and 24. Their arrival heralds the end of a long development process that began in infancy.
But this auspicious event can give rise to dental problems. Because they’re the last to come in, wisdom teeth often erupt in an environment crowded by earlier teeth. Depending on jaw size and other factors, there may not be enough room for a normal eruption.
Wisdom teeth can thus erupt out of position, creating a poor bite (malocclusion). Or they might not erupt at all—becoming stuck fully or partially within the gums and bone, a condition known as impaction. Impacted teeth can also cause problems for the adjacent teeth, damaging the roots of the second molars or disrupting the surrounding gum tissue, making them more susceptible to periodontal (gum) disease.
Because of these and other issues, impacted wisdom teeth are among the most common type of teeth removed: an estimated 10 million each year. And many of these are removed before they show signs of disease or complications as a preemptive strike against developing dental problems.
Although unnecessary surgery should always be avoided, according to some research, there’s a one in three chance that erupting wisdom teeth that are not showing signs of trouble will eventually become problematic. And the earlier they’re removed, the lower the risk of post-extraction complications.
Wisdom teeth should always be evaluated on a case by case basis. Those with obvious signs of disease or complications do require prompt treatment, including possible extraction. Others that are asymptomatic can be monitored over time: If they’re tending to become problematic, we can adjust the treatment plan accordingly. Our goal is to ensure these particular teeth signaling the end of childhood won’t detract from dental health in adulthood, so a measured approach seems to be the best and safest one.

While braces are often the stars for straightening smiles, they're not the only cast members in an orthodontic production. Orthodontists occasionally turn to other appliances if the bite problem is challenging. Whatever the tool, though, they usually have something in common—they use the principle of anchorage.
To understand anchorage, let's first consider the classic kid's game Tug of War. With teams on either end of a rope, the object is to pull the opposing team across the center line before they pull you. To maximize your pulling force, the player at the back of your rope, usually your stoutest member, holds steady or "anchors" the rest of the team.
Like a Tug of War team, braces exert force against the teeth. This stimulates the supporting periodontal ligament to remodel itself and allow the teeth to move. The braces use the teeth they are attached to as anchors, which in a lot of cases are the back teeth. By attaching a thin wire to the brackets or braces on the teeth, the orthodontist includes all the teeth on the arch, from one end to the other. Anchored in place, the wire can maintain a constant pressure against the teeth to move them.
But not all bite situations are this straightforward. Sometimes an orthodontist needs to influence jaw growth in addition to teeth movement. For this purpose, they often use orthodontic headgear, which runs around the back of the head or neck and attaches to orthodontic brackets on the teeth. It still involves an anchor but in this case it's the patient's own skull.
In some situations, an orthodontist may feel he or she needs more anchorage as the teeth alone may not be enough. For this, they might establish a separate or additional anchor point using a temporary anchorage device (TAD). A TAD resembles a tiny screw that's inserted into the jawbone near the tooth intended for movement. The orthodontist can then attach the TAD to braces hardware using some form of elastics. After treatment, they remove the TAD.
These are just a couple examples of specialized tools an orthodontist can use for bite correction. Thanks to them and similar devices, even the most complex bite problem can be overcome to create a healthier and more attractive smile.

Occurrences of obesity and Type 2 diabetes have soared in the last few decades. While there are a number of influencing factors, health officials place most of the blame on one of our favorite foods: sugar. Only a generation ago we were consuming an annual average of 4 pounds per person. Now, it's nearly 90 pounds.
We've long known that sugar, a favorite food not only for humans but also oral bacteria, contributes to dental disease. But we now have even more to concern us—the effect of increased sugar consumption on health in general.
It's time we took steps to rein in our favorite carbohydrate. Easier said than done, of course—not only is it hard to resist, it's also hard to avoid. With its steady addition over the years to more and more processed foods, nearly 77% of the products on grocery store shelves contain some form of sugar.
Here's what you can do, though, to reduce sugar in your diet and take better care of your dental and general health.
Be alert to added sugar in processed foods. To make wiser food choices, become familiar with the U.S.-mandated ingredient listing on food product packaging—it tells if any sugar has been added and how much. You should also become acquainted with sugar's many names like "sucrose" or "high fructose corn syrup," and marketing claims like "low fat" that may mean the producer has added sugar to improve taste.
Avoid sodas and other prepared beverages. Some of the highest sources for added sugar are sodas, sports drinks, teas or juice. You may be surprised to learn you could consume your recommended daily amount of sugar in one can of soda. Substitute sugary beverages with unsweetened drinks or water.
Exercise your body—and your voice. Physical activity, even the slightest amount, helps your body metabolize the sugar you consume. And speaking of activity, exercise your right to have your voice heard by your elected officials in support of policy changes toward less sugar additives in food products.
Becoming an informed buyer, disciplined consumer and proactive citizen are the most important ingredients for stopping this destructive health epidemic. Your teeth—and the rest of your body—will thank you.
