LifeIsSometimesaGrindforBrookeShields

Ever since childhood, when her career as a model and actress took off, Brooke Shields has enjoyed worldwide recognition — through advertisements for designer jeans, appearances on The Muppet Show, and starring roles in big-screen films. But not long ago, that familiar face was spotted in an unusual place: wearing a nasal anesthesia mask at the dentist's office. In fact, Shields posted the photo to her own Instagram account, with the caption “More dental surgery! I grind my teeth!” And judging by the number of comments the post received, she's far from alone.

In fact, researchers estimate that around one in ten adults have dental issues that stem from teeth grinding, which is also called bruxism. (Many children also grind their teeth, but it rarely causes serious problems, and is often outgrown.) About half of the people who are teeth grinders report problems like persistent headaches, jaw tenderness and sore teeth. Bruxism may also result in excessive tooth wear, and may damage dental work like crowns and bridges; in severe cases, loosened or fractured teeth have been reported.

Researchers have been studying teeth grinding for many years; their findings seem to indicate that it has no single cause. However, there are a number of factors that play a significant role in this condition. One is the anatomy of the jaw itself, and the effect of worn or misaligned teeth on the bite. Another factor relates to changes in brain activity that occur during the sleep cycle. In fact, nocturnal (nighttime) bruxism is now classified as a sleep-related movement disorder. Still other factors, such as the use of tobacco, alcohol and drugs, and a high level of stress or anxiety, can make an individual more likely to experience bruxism.

What can be done for people whose teeth grinding is causing problems? Since this condition may have many causes, a number of different treatments are available. Successful management of bruxism often begins by striving to eliminate the factors that may cause problems — for example, making lifestyle changes to improve your health, creating a soothing nighttime environment, and trying stress-reduction techniques; these may include anything from warm baths and soft music at bedtime, to meditation and mindfulness exercises.

Several dental treatments are also available, including a custom-made occlusal guard (night guard) that can keep your teeth from being damaged by grinding. In some cases, a bite adjustment may also be recommended: In this procedure, a small amount of enamel is removed from a tooth to change the way it contacts the opposite tooth, thereby lessening the biting force on it. More invasive techniques (such as surgery) are rarely needed.

A little tooth grinding once in a while can be a normal response to stress; in fact, becoming aware of the condition is often the first step to controlling it. But if you begin to notice issues that could stem from bruxism — or if the loud grinding sounds cause problems for your sleeping partner — it may be time to contact us or schedule an appointment. You can read more about bruxism in the Dear Doctor magazine article “Stress and Tooth Habits.”

ExtractingCertainTeethcanBoostOrthodonticEffectiveness

We treat most malocclusions (bad bites) with braces or clear aligners. But not all malocclusions are alike — some can require extra procedures to achieve successful results.

One such example is when incoming teeth crowd other teeth and cause them to erupt abnormally. The crowding also reduces the space needed to move the misaligned teeth to better positions. To make more room we'll often remove some of the teeth before undertaking orthodontics.

The key is to extract the right teeth. The best candidates are those whose absence will have minimal effect on both appearance and dental function. That's commonly the bicuspids, located right on the edge of the “smile zone” (the teeth most visible when we smile) between the cuspid (eye) teeth and the back molars.

Once we choose and remove the teeth our next concern is to protect the bone at the extraction site. The bone in our jaws benefits from the pressure created when we bite or chew. This stimulates new bone cells to form and replace older cells. Without it, as when we have a missing tooth, the amount of bone can diminish over time and affect the success of any future orthodontics.

To prevent this, we take care not to damage the gums and bone removing the tooth. We may also install a graft under the empty socket to encourage bone growth.

If we've removed teeth outside the smile zone, the resulting orthodontics will move teeth into the opened space. In the end, you won't even notice they're gone. Teeth lost or congenitally missing in the smile zone, though, may eventually require a replacement tooth. A dental implant is the best choice, but it should be put on hold for a younger person until their jaw has fully developed.

In the meantime, we can install a spacer or a temporary restoration to hold the empty space and prevent other teeth from drifting into it. This can be incorporated into braces or aligners, or with a removable partial denture or a temporary modified bridge.

Extracting teeth to aid orthodontics first requires a well-laid plan that could encompass several years. The end result, though, can be well worth the time and effort — better function and a new, attractive smile.
