After your son or daughter's dental exam, you expect to hear about cavities, poor bites or other dental problems. But your dentist might suggest a different kind of problem you didn't expect—an eating disorder.
It's not a fluke occurrence—a dental exam is a common way bulimia nervosa or anorexia nervosa come to light. That's because the teeth are often damaged by the behaviors of a patient with an eating disorder.
Most of this damage occurs because of purging, the practice of induced vomiting after eating. During vomiting stomach acid can enter the mouth and "wash" against the back of the teeth. After repeated episodes, the acid dissolves the mineral content of tooth enamel and causes it to erode. There's also a tell-tale pattern with eating disorders: because the tongue partially shields the back of the lower teeth while purging, the lower teeth may show less enamel erosion than the upper.
Hygiene practices, both negligent and too aggressive, can accelerate erosion. Anorexics often neglect basic grooming and hygiene like brushing and flossing, which increases the likelihood of dental disease. Bulimia patients, on the other hand, can be fastidious about their hygiene. They're more likely to brush immediately after purging, which can cause tiny bits of the enamel immediately softened by the acid wash to slough off.
In dealing with a family member's eating disorder, you should consider both a short and long-term approach to protect their dental health. In the sort-term the goal is to treat the current damage and minimize the extent of any future harm. In that regard, encourage them to rinse with water (mixed optionally with baking soda to help neutralize acid) after purging, and wait an hour before brushing. This will give saliva in the mouth a chance to fully neutralize any remaining acid. Your dentist may also recommend a sodium fluoride mouth rinse to help strengthen their tooth enamel.
For the long-term, your goal should be to help your loved one overcome this potentially life-threatening condition through counseling and therapy.

It's no secret that many of Hollywood's brightest stars didn't start out with perfectly aligned, pearly-white teeth. And these days, plenty of celebs are willing to share their stories, showing how dentists help those megawatt smiles shine. In a recent interview with W magazine, Emma Stone, the stunning 28-year-old star of critically-acclaimed films like La La Land and Birdman, explained how orthodontic appliances helped her overcome problems caused by a harmful habit: persistent thumb sucking in childhood.
“I sucked my thumb until I was 11 years old,” she admitted, mischievously adding “It's still so soothing to do it.” Although it may have been comforting, the habit spelled trouble for her bite. “The roof of my mouth is so high-pitched that I had this huge overbite,” she said. “I got this gate when I was in second grade… I had braces, and then they put a gate.”
While her technical terminology isn't quite accurate, Stone is referring to a type of appliance worn in the mouth which dentists call a “tongue crib” or “thumb/finger appliance.” The purpose of these devices is to stop children from engaging in “parafunctional habits” — that is, behaviors like thumb sucking or tongue thrusting, which are unrelated to the normal function of the mouth and can cause serious bite problems. (Other parafunctional habits include nail biting, pencil chewing and teeth grinding.)
When kids develop the habit of regularly pushing the tongue against the front teeth (tongue thrusting) or sucking on an object placed inside the mouth (thumb sucking), the behavior can cause the front teeth to be pushed out of alignment. When the top teeth move forward, the condition is commonly referred to as an overbite. In some cases a more serious situation called an “open bite” may develop, which can be difficult to correct. Here, the top and bottom front teeth do not meet or overlap when the mouth is closed; instead, a vertical gap is left in between.
Orthodontic appliances are often recommended to stop harmful oral habits from causing further misalignment. Most appliances are designed with a block (or gate) that prevents the tongue or finger from pushing on the teeth; this is what the actress mentioned. Normally, when the appliance is worn for a period of months it can be expected to modify the child's behavior. Once the habit has been broken, other appliances like traditional braces or clear aligners can be used to bring the teeth into better alignment.
But in Stone's case, things didn't go so smoothly. “I'd take the gate down and suck my thumb underneath the mouth appliance,” she admitted, “because I was totally ignoring the rule to not suck your thumb while you're trying to straighten out your teeth.” That rule-breaking ended up costing the aspiring star lots of time: she spent a total of 7 years wearing braces.
Fortunately, things worked out for the best for Emma Stone: She now has a brilliant smile and a stellar career — plus a shiny new Golden Globe award!

Long ago dental work could be painful and stressful—often for both patient and practitioner. Thankfully, that time is long past: today, most procedures are painless in large part due to local anesthesia.
Local anesthetics are numbing substances applied to specific areas of the body like the teeth and gums to temporarily block pain during a procedure. And because they only affect a localized area of the body, you remain conscious and alert throughout the procedure.
To achieve the level of numbing necessary for dental work, we often need to deaden the gums using a needle to deliver the anesthetic. But then this poses a secondary pain concern—the needle stick itself.
Again, topical anesthesia comes to the rescue in the form of a swab, patch or spray applying an anesthetic directly to the top layer of the gums at the injection site. This numbs the area and prevents you from feeling the needle stick. It's highly probable, therefore, that from start to finish you won't feel any discomfort during your dental work except perhaps for a little pressure.
Local anesthesia truly is a game changer for dental care—and not just for the patient. A dentist who's concerned about their patient's comfort level may work hurriedly to complete a procedure. But if their patient is relaxed, the dentist can work calmly and methodically. The result is better, more focused care.
For all its improvements in the patient experience, though, there has been one consistent complaint—the numbness that often lingers for a while after the procedure is over. But there have been advances in recent years that have helped reduce this irritation: new anesthetic agents (even some that can reverse the anesthetic effect) and fine-tuned dosages can help keep residual numbing to a minimum.
Not all procedures like routine teeth cleanings or enamel shaping require anesthesia. But when it's appropriate, local anesthesia can make your next dental visit much more pleasant.
