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.”
You've been treating a persistent rash around your mouth with medicated ointments, but it's not going away. The problem may be the ointment — it could actually be sustaining the particular rash you have.
Peri-oral dermatitis is a scaly rash with small bumps (some filled with pus) around the mouth, eyes or nose. It's especially common among women ages 20-45, possibly due to hormonal factors or cosmetic use. Other than its unattractiveness you might not otherwise notice it, although it can cause stinging, itching or burning. There are ways to treat it effectively, though not necessarily the way you might think.
Many skin conditions respond well to topical steroids, like ointments or lotions containing hydrocortisone. But prolonged use of a steroid for skin irritations might actually increase risks for peri-oral dermatitis. Applying it to an existing rash may also deceive you — the steroid constricts some of the skin's tinier blood vessels, which will make the rash appear as if it's fading. The effect, though, usually doesn't last more than an hour. If you continue to use the steroid, the rash won't get better.
The key to alleviating peri-oral dermatitis requires treatment from a physician, dermatologist or dentist, who will also be able to accurately diagnose the specific skin condition you have. If it is peri-oral dermatitis, the first step is to stop using any topical steroids and only wash with mild soap or similar substitute. You'll have to be patient because the rash may at first appear to flare up and worsen before getting better.
Instead of steroids, we may prescribe antibiotics to help clear the rash, typically tetracycline. It may take several weeks of use before the rash begins to clear; as it does clear, you would either stop the antibiotic treatment or taper off over a four-to-five week period.
While some cases of peri-oral dermatitis will clear up and remain that way, some people may experience chronic reoccurrences. Even so, by using the same treatment approach we can still effectively manage the condition for the long-term.
When is the best time to floss your teeth: Morning? Bedtime? How about: whenever and wherever the moment feels right?
For Cam Newton, award-winning NFL quarterback for the Carolina Panthers, the answer is clearly the latter. During the third quarter of the 2016 season-opener between his team and the Denver Broncos, TV cameras focused on Newton as he sat on the bench. The 2015 MVP was clearly seen stretching a string of dental floss between his index fingers and taking care of some dental hygiene business… and thereby creating a minor storm on the internet.
Inappropriate? We don't think so. As dentists, we're always happy when someone comes along to remind people how important it is to floss. And when that person has a million-dollar smile like Cam Newton's — so much the better.
Of course, there has been a lot of discussion lately about flossing. News outlets have gleefully reported that there's a lack of hard evidence at present to show that flossing is effective. But we would like to point out that, as the saying goes, “Absence of evidence is not evidence of absence.” There are a number of reasons why health care organizations like the American Dental Association (ADA) still firmly recommend daily flossing. Here are a few:
- It's well established that when plaque is allowed to build up on teeth, tooth decay and gum disease are bound to follow.
- A tooth brush does a good job of cleaning most tooth surfaces, but it can't reach into spaces between teeth.
- Cleaning between teeth (interdental cleaning) has been shown to remove plaque and food debris from these hard-to-reach spaces.
- Dental floss isn't the only method for interdental cleaning… but it is recognized by dentists as the best way, and is an excellent method for doing this at home — or anywhere else!
Whether you use dental floss or another type of interdental cleaner is up to you. But the ADA stands by its recommendations for maintaining good oral health: Brush twice a day for two minutes with fluoride toothpaste; visit your dentist regularly for professional cleanings and checkups; and clean between teeth once a day with an interdental cleaner like floss. It doesn't matter if you do it in your own home, or on the sidelines of an NFL game… as long as you do it!
