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.

When your baby’s first teeth come in, you might not think it necessary yet to worry about tooth decay. But even infants can develop this common dental disease. In fact, it has a specific name in children 6 and under: early childhood caries (ECC).
About one-fourth of U.S. children have ECC, and poor or minority children are at highest risk. Because of primary (“baby”) teeth’s thin enamel layer, ECC can spread to healthier teeth with unnerving speed, causing extensive damage.
While such damage immediately affects a child’s nutrition, speech development and self-esteem, it could also impact their future oral health. Permanent teeth often erupt out of position because of missing primary teeth lost prematurely, creating a poor bite. And children with ECC are more likely to have cavities in their future permanent teeth.
While there are a number of effective treatments for repairing ECC-caused damage, it’s best to try to prevent it before damage occurs. A large part of prevention depends on you. You should, for example, begin oral hygiene even before teeth come in by wiping their gums with a clean, damp cloth after feeding. After teeth appear, switch to daily brushing with just a smear of toothpaste.
Because refined sugar is a primary food source for decay-causing bacteria, you should limit it in their diet. In the same vein, avoid sleep-time bottles with fluids like juices, milk or formula. As they grow older, make sure snacks are also low in sugar.
You should also avoid spreading your own oral bacteria to your baby. In this regard, don’t put their eating utensils or pacifier in your mouth and don’t drink from the same cup. Avoid kissing your baby on the lips. And above all, take care of your own oral health to prevent your own encounter with dental disease.
Finally, start regular dental visits on or before your baby’s first birthday. Regular cleanings and checkups increase the chances for early decay detection, as well as provide for treatments and prevention measures that can reduce the disease’s spread and destruction.
ECC can be devastating to both your baby’s current and future dental health. But with vigilance and good dental practices, you may be able to help them avoid this serious disease.
Contrary to what you might think, a knocked out tooth doesn’t inevitably mean tooth loss. Time is of the essence — the shorter the interval between injury and replanting the tooth, the better the tooth’s long-term survival. The longer the interval, on the other hand, the less likely the tooth can survive beyond a few years. That phenomenon is due to the mouth’s natural mechanism for holding teeth in place.
The tooth root maintains its attachment with the jaw bone through an intermediary tissue known as the periodontal ligament. Tiny fibers from one side of the ligament securely attach to the tooth root, while similar fibers attach to the bone on the opposite side of the ligament. This maintains stability between the teeth and bone while still allowing incremental tooth movement in response to mouth changes like tooth wear.
While the ligament fibers will attempt to reattach to a replanted tooth’s root, the longer the tooth is out of the socket the less likely the fibers will fully reattach. An “ankylosis” may instead form, in which the root attaches directly to the jaw bone without the periodontal ligament. In this situation the body no longer “recognizes” the tooth and begins to treat it like a foreign substance. In all but the rarest cases, the tooth root will begin to resorb (dissolve); at some point (which varies from patient to patient) the attachment becomes too weak for the tooth to remain in place and is lost.
Ideally, a knocked out tooth should be replanted within 5 minutes of the injury (for step-by-step instructions, refer to The Field-Side Guide to Dental Injuries available on-line at www.deardoctor.com/dental-injuries). Even if you pass the 5-minute window, however, it’s still advisable to attempt replanting. With a subsequent root canal treatment (to remove dead tissue from the inner tooth pulp and seal it from infection), it’s possible the tooth can survive for at least a few years, plenty of time to plan for a dental implant or similar tooth replacement.
