While most dental problems are caused by disease or trauma, sometimes the root problem is psychological. Such is the case with bulimia nervosa, an eating disorder that could contribute to dental erosion.
Dental erosion is the loss of mineral structure from tooth enamel caused by elevated levels of acid in the mouth, which can increase the risk for decay and eventual tooth loss. While elevated acid levels are usually related to inadequate oral hygiene or over-consumption of acidic foods and beverages, the practice of self-induced vomiting after food binging by bulimic patients may also cause it. Some of the strong stomach acid brought up by vomiting may remain in the mouth afterward, which can be particularly damaging to tooth enamel.
It’s often possible to detect bulimia-related erosion during dental exams. The bottom teeth are often shielded by the tongue during vomiting, so erosion may be more pronounced on the unshielded upper front teeth. The salivary glands may become enlarged, giving a puffy appearance to the sides of the face below the ears. The back of the mouth can also appear red and swollen from the use of fingers or objects to induce vomiting.
Self-induced vomiting may not be the only cause for dental erosion for bulimics. Because the disorder causes an unhealthy focus on body image, bulimics may become obsessed with oral hygiene and go overboard with brushing and flossing. Aggressive brushing (especially just after throwing up when the tooth enamel may be softened) can also damage enamel and gum tissue.
Treatment must involve both a short — and long-term approach. Besides immediate treatment for dental erosion, a bulimic patient can minimize the effect of acid after vomiting by not brushing immediately but rinsing instead with water, mixed possibly with a little baking soda to help neutralize the acid. In the long-term, though, the eating disorder itself must be addressed. Your family doctor is an excellent starting point; you can also gain a great deal of information, both about eating disorders and treatment referrals, from the National Eating Disorders Association at their website, www.nationaleatingdisorders.org.
The effects of bulimia are devastating to mental and physical well-being, and no less to dental health. The sooner the disorder can be treated the better the person’s chance of restoring health to their mind, body — and mouth.

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.”
In the quest for the ideal diet, people often stress over one particular food group: carbohydrates. And for good reason—some carbohydrates have been linked to chronic inflammation, a contributing factor in many diseases. One such condition in particular, periodontal (gum) disease, could permanently damage your dental health.
But before you throw all the carbs out of your diet, let’s take a closer look at them. Not all carbs are the same or contribute to inflammation to the same degree.
Carbohydrates are organic compounds existing in living tissues. In foods, the most prevalent of these are sugars and starches that break down during digestion into the simple sugar glucose, which the cells in an organism use for energy.
But not all carb-based foods digest at the same rate, measured along a scale called the glycemic index. High glycemic foods like sugar, baked goods or potatoes digest quickly and can rapidly increase the glucose levels in the blood (blood sugar). This sudden glucose spike then triggers an insulin surge from the pancreas to restore the level to normal. This process in turn can cause inflammation.
On the other end of the glycemic index are complex or unrefined carbohydrates that digest much more slowly, and don’t quickly elevate blood sugar like simple carbs. In fact, nutritional studies consistently show carbohydrates in most vegetables, greens, beans or whole grains may actually decrease inflammation.
Inflammation is also a primary factor in gum disease, caused by a bacterial infection in the gums. Chronic inflammation damages the gums’ attachment with the teeth and can contribute to eventual tooth loss. And if your body already has an overactive inflammatory response due to your diet, you could be even more susceptible to gum disease.
A change in your diet in relation to carbs could help reduce this risk. Eat less sugar, white flour, rice and potatoes and more complex carbs like fresh vegetables and fruits. For even more protection include foods rich in Omega-3 fatty acids (like certain fish and nuts) and less Omega 6 foods (fried food or pastries, or chips, for example). And don’t forget your antioxidants, vitamins and minerals.
Eating fewer simple carbs and more complex carbs will help reduce inflammation in the body. And that’s a good thing for your gums.
