Thyroid hormone imbalance may cause several mouth and dental health issues.

Burning Mouth Syndrome

Some thyroid patients, especially middle-aged women or women in menopause, develop Burning Mouth Syndrome (BMS). As the name suggests, BMS is characterized by a burning sensation on the tongue or the lips or involving the whole mouth. It may be accompanied by a bitter or metallic taste. Treatment for thyroid disease can improve the symptoms of BMS.

Dry Mouth

Decreased saliva production sometimes accompanies thyroid disease. Dry mouth may appear on its own or it may be caused by another autoimmune disease that accompanies thyroid problems, such as Sjogren’s syndrome. Dry mouth itself can be an uncomfortable condition, but it also causes increased incidences of mouth sores, tooth decay, and difficulty swallowing. Taking medication to balance thyroid hormone levels may reduce dry mouth symptoms. If you still experience problems, your dentist can recommend both over-the-counter and prescription medications to treat dry mouth.

Hypothyroidism

Patients with hypothyroidism, also known as underactive thyroid, may experience macroglossia (enlargement of the tongue), gum disease, slow healing of mouth sores, and, in children, delayed tooth growth. Problems with hypoglycemia (low blood sugar) are common in patients with underactive thyroids and can cause an increased risk of mouth and tooth infections.

Talking to Your Dentist

If you have thyroid disease, it is important to get regular dental checkups and to talk to your dentist about your thyroid problem. Medications associated with secondary conditions of thyroid disease, such as heart problems, may affect the way you respond to anesthesia and may impact how your blood clots. Your dentist needs to know about these risks before performing any procedures. Likewise, when your dentist is aware of your thyroid disease, they can become a partner in helping you manage it.
