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.

One of the key parts to an effective oral disease prevention plan is practicing daily oral hygiene to remove dental plaque. Both brushing and flossing are necessary for cleaning your teeth of this thin biofilm of bacteria and food particles most responsible for tooth decay and periodontal (gum) disease.
But as important as they are, these two essential hygiene tasks aren’t the end-all-be-all for lowering your disease risk. For the best protection, you should also visit your dentist at least twice a year for thorough dental cleanings. That’s because plaque you might have missed can turn into something much more difficult to remove: calculus.
Also known as tartar, calculus is hardened deposits of plaque. The term comes from the Latin word meaning “small stone,” an apt description of its texture on tooth surfaces. Although not the same as the branch of mathematics that bears the same name, both derive from the same Latin word: Merchants and traders centuries ago used small stones to “calculate” their various transactions.
Over time soft and pliable dental plaque hardens into calculus, in part due to a reaction with saliva. Because of the difficulty of accessing all tooth surfaces, calculus can form even if you have an effective daily hygiene practice.
Once formed, calculus can adhere to teeth so tenaciously, it’s impossible to remove it with brushing and flossing. But dentists and hygienists can remove calculus safely with special tools called scalers.
And it should be removed or it will continue to foster bacterial growth. This in turn increases the chances for infections that attack the teeth, gums or underlying bone. Keeping it under control will therefore diminish your risk for developing dental disease.
Although there are other factors like heredity that can affect your disease risk, keeping your mouth clean is the number one thing you can do to protect your teeth and gums. A daily hygiene practice and regular dental visits will help ensure plaque and its calcified form calculus won’t be a problem.
There is a primary principle dentists follow regarding tooth decay—treat it as soon as you find it. Something as simple and routine as filling a cavity could prevent future tooth loss.
But treating a cavity at or below the gum line could be anything but simple and routine. Older adults who may also be dealing with gum recession are more likely to have these kinds of cavities where the gums block clear access to it.
But there is a way to access gum-covered cavities with a minor surgical procedure known as crown lengthening. Crown lengthening is commonly used in cosmetic dentistry to expose more of the visible teeth when there's an overabundance of gum tissue or if the teeth are disproportionately small. We can use it in this instance to surgically relocate the blocking gum tissue out of the way of the cavity.
After numbing the area with local anesthesia, tiny incisions will be made in the gums to create a tissue flap. After reshaping the underlying bone to recreate normal anatomy but at a different level, this flap is then moved and sutured to a new position. This exposes enough tooth structure so that the cavity can be repaired after gum healing.
As with any minor surgery, there's a very slight risk of bleeding and/or infection with crown lengthening. If you undergo this procedure, you'll receive post-care instructions for the first few days afterward including avoiding strenuous activities, eating only soft foods and using an ice pack the day of surgery to help control swelling.
This versatile procedure can help save a tooth that might otherwise be lost due to decay. And, it might even improve your appearance.
