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.

"Mom, my tooth hurts" isn't something you look forward to hearing your child say. But tooth pain is as common as other childhood ailments, so you may have to face it. Here are a few simple steps to make it easier.

First, ask your child where in the mouth it hurts and, if they can, tell you how long it's been hurting. Children's memories aren't always accurate, but you can still get a general idea that you can communicate with your dentist if you take them in.

Next, look in their mouth for anything out of the ordinary: gum swelling or bleeding, or dark spots on the teeth indicative of tooth decay. Look also for hard food particles like popcorn kernels caught between the teeth, which could be causing the pain. Gently floss between the teeth (even if you can't see anything) to remove any caught particles.

You'll also want to help ease their pain. You can apply an ice pack against the painful side of the jaw. Don't place ice directly on the skin, but use a container or cloth alternately against the jaw for a minute or so, and then away for a minute. You can also give them a dose of mild pain reliever like ibuprofen or acetaminophen appropriate for their age and weight—but never rub aspirin or other pain relievers on the gums, which tend to be acidic and can burn the skin.

Finally, you'll need to decide if you need to see a dentist and how soon. It might not be necessary with situations like the trapped food particles, but most of the time it's wise to have your dentist perform an examination for an accurate diagnosis and appropriate treatment. As to how soon, try to see the dentist immediately if the pain has continued from one day to the next or has kept your child up overnight. Otherwise, book an appointment for as soon as the dentist advises, even if the pain subsides.

A toothache at any age is never pleasant, but especially for children. Knowing these steps will help ease their discomfort and get them the relief and treatment they need.

Teenagers and adults alike can improve their smile appearance with dental solutions like teeth whitening or orthodontics. But there are a few cosmetic solutions like porcelain veneers that are better suited for more mature teeth.

Veneers are composed of thin layers of dental porcelain that are bonded to the outside of teeth. They're kind of a tooth "mask" that hides blemishes like chips, discoloration or mild bite problems. They're often less involved and expensive than other types of dental restoration.

Even so, we usually need to remove some of the natural tooth's enamel before applying them. Veneers placed directly on unprepared teeth can appear bulky, so we remove some of the enamel to create a more natural look. And although usually only a slight amount, the alteration is permanent and will require the tooth to have some form of restoration from then on.

This usually doesn't pose a major issue for adults, but it could for a teenager's younger teeth. The nerve-filled dentin in a teenager's still developing tooth is thinner and closer to the pulp (nerve tissue) than in more mature teeth.

There's at least one situation, though, where veneers might be applied safely to a teenager's teeth without this concern. If the teen has abnormally small teeth and are receiving veneers to improve their appearance, they might not need alteration. Because the teeth are already thinner than normal, the "no-prep" veneers may not look bulky when directly bonded to them without preparation.

With most cases, though, it might be best to pursue other options that at the very least can make a cosmetic difference until their teeth are mature enough for veneers. For example, we might be able to repair chipped areas with composite resin material that we form and bond to the tooth to achieve a life-like appearance.

We can discuss these and other options for safely improving your teenager's smile. The important thing is to achieve a more confident appearance without endangering their future health.
