About 20% to 30% of adults experience recurrent stomatitis, a condition marked by inflammation and redness in the mouth, leading to canker sores, painful blisters, and ulcers. Stomatitis can turn eating, drinking, and swallowing into an excruciating experience. Treatment is essential to ensure no lapse in the adequate intake of nutrients.


1. Causes

Stomatitis can be caused by improper dental care, infection, or disease. It can also be an allergic reaction, a complication of smoking, or the result of burns from excessively hot foods or beverages. Xerostomia or dry mouth increases the risk of stomatitis because the lack of saliva makes infection more likely. Other predisposing factors include stress, oral trauma, and a family history of the condition.
