Dental Enamel Defects & Celiac Disease

Celiac disease manifestations can extend beyond the classic gastrointestinal problems, affecting any organ or body system. One manifestation—dental enamel defects—can help dentists and other health care providers identify people who may have celiac disease and refer them to a gastroenterologist. For some people with celiac disease, a dental visit, rather than a trip to the gastroenterologist, was the first step toward discovering their condition.

Not all dental enamel defects are caused by celiac disease, although the problem is fairly common among people with the condition, particularly children, according to Alessio Fasano, M.D., medical director at the Massachusetts General Hospital for Celiac Research and Treatment. And dental enamel defects might be the only presenting manifestations of celiac disease.

Dental enamel problems stemming from celiac disease involve permanent dentition and include tooth discoloration—white, yellow, or brown spots on the teeth—poor enamel formation, pitting or banding of teeth, and mottled or translucent-looking teeth. The imperfections are symmetrical and often appear on the incisors and molars.

Tooth defects resulting from celiac disease are permanent and do not improve after adopting a gluten-free diet—the primary treatment for celiac disease. However, dentists may use bonding, veneers, and other cosmetic solutions to cover dental enamel defects in older children and adults.

Similar Symptoms, Different Problem

Tooth defects that result from celiac disease may resemble those caused by too much fluoride or a maternal or early childhood illness.

“Dentists mostly say it’s from fluoride, that the mother took tetracycline, or that there was an illness early on,” said Peter H.R. Green, M.D., director of the Celiac Disease Center at Columbia University. “Celiac disease isn’t on the radar screen of dentists in this country. Dentists should be made aware of these manifestations to help them identify people and get them to see their doctors so they can exclude celiac disease.”

Green just completed a U.S. study with his dental colleague, Ted Malahias, D.D.S., that demonstrates celiac disease is highly associated with dental enamel defects in childhood—most likely due to the onset of celiac disease during enamel formation. The study, which did not identify a similar association in adults, concluded that all physician education about celiac disease should include information about the significance of dental enamel defects.

Other Oral Symptoms

Checking a patient’s mouth is something primary care physicians also can do to help identify people who might have celiac disease. While dental enamel defects are the most prominent, a number of other oral problems are related to celiac disease, according to Green. These include

• recurrent aphthous stomatitis, or canker sores or ulcers that recur inside the mouth
• atrophic glossitis, a condition characterized by a red, smooth, shiny tongue
• dry mouth syndrome
• squamous cell carcinoma—a type of cancer—of the pharynx and mouth
