10 Causes of Mouth Ulcers
Cause #5: Aphthous Stomatitis
Another extremely common cause of mouth ulcers is aphthous stomatitis or also commonly known as “canker sores”. They affect as many as 10 to 25 percent of the general population. They are non-contagious and can be divided into three types: minor aphthous ulceration, major aphthous ulceration, and herpetiform ulceration. The minor variant occurs when the ulcers are small (2 to 4 mm in diameter) with a red halo.
The major type occurs when the ulcers are more than one centimeter in diameter and may result in scarring. Herpetiform ulceration is the least common. It begins with multiple small blisters or vesicles which then break down to become 2 to 3 mm sized ulcers.
