A mouth ulcer can be described as a sore that hurts that develops within the mouth. Mouth ulcers can be found in the mouth, the cheeks, the gums, or even on the lips. They’re usually oval or round and may be yellow, white, or gray in hue. Mouth ulcers may be caused by bites on the cheek’s inside or mouth, braces, dentures, or certain kinds of food.

In certain instances, mouth ulcer could indicate a more severe issue that could be a sign of a cancerous or immune-related disorder. You should visit a dentist or doctor if you’re experiencing mouth ulcers that don’t disappear within a couple of weeks or have other uncured signs.

Mouth ulcers: Causes

Acidic foods, such as citrus fruits, may aggravate mouth ulcers.
