Mouth ulcers are ulcers that occur on the mucous membranes of the mouth. It is a very common issue that can be seen in various conditions. Mouth ulcers often cause pain, difficulty eating, discomfort, and can also affect food choice, as certain foods may cause more pain.
Mouth ulcers can appear individually or there may be multiple ones that appear at the same time. An ulcer is defined as a break in the mucous membrane, or skin, where there is disintegration, loss of surface, and necrosis of the tissue surface.
Mouth Ulcers Cause #1: Trauma
The most common cause of mouth ulcers is trauma to the lining of the mouth due to fillings, crowns, dentures, and braces. Accidental biting can also cause ulceration especially after the use of a local anesthetic during dental treatment, which decreases awareness of pain in the mouth. Foods that are rough can also damage the lining of the mouth causing trauma and subsequently, ulceration.
