Orthodontics shares a principle with the classic tug of war game: if you want things to move in the right direction you need a good anchor. Anchors help braces and other appliances apply constant pressure to misaligned teeth in the direction they need to go to correct a malocclusion (poor bite).
Orthodontic treatments work in cooperation with an existing oral mechanism that already moves teeth naturally in response to biting forces or other environmental factors. The key to this mechanism is an elastic tissue known as the periodontal ligament that lies between the tooth and the bone. Besides holding teeth in place through tiny attached fibers, the ligament also allows the teeth to move in tiny increments.
Braces’ wires laced through brackets affixed to the teeth exert pressure on them in the desired direction of movement –the periodontal ligament and other structures do the rest. To maintain that pressure we need to attach them to an “anchor”—in basic malocclusions that’s usually the back molar teeth.
But not all malocclusions are that simple. Some may require moving only certain teeth while not moving their neighbors. Younger patients’ jaws and facial structures still under development may also need to be considered during orthodontic treatment. That’s why orthodontists have other anchorage methods to address these possible complications.
One example of an alternate anchorage is a headgear appliance that actually uses the patient’s skull as the anchor. The headgear consists of a strap running around the back of the head and attached in front to orthodontic brackets (usually on molar teeth). The pressure it exerts can trigger tooth movement, but it can also help influence jaw development if an upper or lower jaw is growing too far forward or back.
Another useful anchorage method is a tiny metal screw called a temporary anchorage device (TAD) that is implanted into the jawbone above the teeth through the gums. Orthodontists then attach elastic bands between implanted TADs and specific braces’ brackets or wires to exert pressure on certain teeth but not others with pinpoint accuracy. After treatment the TADs can be easily removed.
Using these and other appliances allows orthodontists to customize treatment to an individual patient’s particular malocclusion. With the right anchor, even the most complex bite problem can be transformed into a beautiful and healthy smile.

Fans of the legendary rock band Steely Dan received some sad news a few months ago: Co-founder Walter Becker died unexpectedly at the age of 67. The cause of his death was an aggressive form of esophageal cancer. This disease, which is related to oral cancer, may not get as much attention as some others. Yet Becker's name is the latest addition to the list of well-known people whose lives it has cut short—including actor Humphrey Bogart, writer Christopher Hitchens, and TV personality Richard Dawson.
As its name implies, esophageal cancer affects the esophagus: the long, hollow tube that joins the throat to the stomach. Solid and liquid foods taken into the mouth pass through this tube on their way through the digestive system. Worldwide, it is the sixth most common cause of cancer deaths.
Like oral cancer, esophageal cancer generally does not produce obvious symptoms in its early stages. As a result, by the time these diseases are discovered, both types of cancer are most often in their later stages, and often prove difficult to treat successfully. Another similarity is that dentists can play an important role in oral and esophageal cancer detection.
Many people see dentists more often than any other health care professionals—at recommended twice-yearly checkups, for example. During routine examinations, we check the mouth, tongue, neck and throat for possible signs of oral cancer. These may include lumps, swellings, discolorations, and other abnormalities—which, fortunately, are most often harmless. Other symptoms, including persistent coughing or hoarseness, difficulty swallowing, and unexplained weight loss, are common to both oral and esophageal cancer. Chest pain, worsening heartburn or indigestion and gastroesophageal reflux disease (GERD) can also alert us to the possibility of esophageal cancer.
Cancer may be a scary subject—but early detection and treatment can offer many people the best possible outcome. If you have questions about oral or esophageal cancer, call our office or schedule a consultation. You can learn more in the Dear Doctor magazine article “Oral Cancer.”
While gum recession is a common occurrence related to aging, it’s not just an “old person’s disease.” It can happen to anyone, even someone with a relatively healthy mouth. And this detachment and shrinking back of the gums from the teeth may not be a minor problem—your dental health is definitely at risk.
Here then are 4 things you should know about gum recession, and what you can do about it.
The most common cause: periodontal (gum) disease. A bacterial infection triggered by built-up dental plaque, gum disease weakens the gums’ attachment to teeth that leads to recession. To help prevent it, clean away plaque with daily brushing and flossing and visit a dentist regularly for more thorough plaque removal. If you already have gum disease, prompt treatment could stop the infection and reduce any resulting damage including recession.
…But not the only one. There are other factors that contribute to recession besides disease. In fact, it could be the result of “too much of a good thing”—brushing too hard and too frequently can damage the gums and lead to recession. You might also be more susceptible to recession if you’ve inherited thin gum tissues from your parents. Thin gums are at increased risk of recession from both disease and over-aggressive hygiene.
Best outcomes result from treating gum disease and/or recession early. The earlier we detect and treat a gum problem, the better the outcome. See your dentist as soon as possible if you see abnormalities like swollen or bleeding gums or teeth that appear larger than before. Depending on your condition there are a number of treatment options like plaque removal or techniques to protect exposed teeth and improve appearance.
Grafting surgery could regenerate lost gum tissue. While with mild cases of gum recession the gums may respond well to treatment and actually rejuvenate on their own, that might not be possible with advanced recession. We may, however, still be able to restore lost tissue through grafting. Using one of a number of techniques, a graft of donor tissue can foster new replacement growth. It’s a meticulous micro-surgical approach, but it could be a viable answer to extreme gum recession.
