What Are the Different Types of Mouth Blisters?
Mouth blisters are irritating and occasionally embarrassing. They may be inside or outside of the mouth. There are various types of mouth lesions, including the common cold sore and canker sore. Brought on by a variety of causes, mouth blisters may last several days. Some types are treatable and others go away on their own. Canker sores are ulcers found inside the mouth. Theses mouth blisters are also called aphthous ulcers. They are visible to the naked eye. Whitish yellow in color, these shallow sores appear with a red border. Though basically round, they are irregular in shape with jagged edges. A canker sore may develop on the cheeks, gums, tongue, or lips — just about anywhere inside the mouth. These mouth blisters range in size, though they are typically smaller than the diameter of a pea. They may cluster or appear singularly. Mouth blisters like this cause additional irritation when eating or even talking. They are extremely painful to the touch.
