People using Ozempic, Wegovy and other GLP-1 medications are reporting a complication not listed among the most common side effects - something which has been dubbed “Ozempic teeth” by dentists, who say the drugs can lead to dry mouth because the active ingredient, semaglutide, affects the salivary glands. The medications can also cause people to drink less water because they feel less thirsty. Those factors combined increase the risk of cavities and gum disease, says Dr. Rajpal Anjali, a cosmetic dentist at Beverly Hills Dental Arts.
