Mouth ulcers are small, superficial sores that occur in the lining of the mouth and are also called “aphthous mouth ulcers.” They start as white to yellow sores surrounded by redness. Food and talk, in this report, deals with the causes and symptoms of mouth ulcers, according to the Cliffend Clinic.
There are two types of mouth ulcers:
Simple mouth sores: They may appear three or four times a year and last for up to a week. Anyone can develop simple mouth ulcers, but they usually occur in people between the ages of 10 and 20.
Complex mouth ulcers: They are less common and occur more often in people who have previously had them.
Causes of mouth ulcers
The exact cause of most mouth ulcers is unknown, and slight stress or injury on the inside of the mouth is thought to be the cause of simple mouth ulcers.
Certain foods – including citrus fruits or acidic fruits and vegetables (such as lemon, oranges, pineapple, apples, figs, tomatoes, and strawberries) – can cause mouth ulcers or make the problem worse.
Using non-steroidal anti-inflammatory drugs, such as ibuprofen, is another common cause.
Sometimes, a sharp tooth surface or dental appliance, such as braces or ill-fitting dentures, can also lead to sores.
Some cases of complex ulcers appear in patients with diseases of the immune system. These include lupus, Behcet’s disease, inflammatory bowel disease (including celiac disease, ulcerative colitis and Crohn’s disease) and AIDS.
Mouth sores also appear in patients who have nutritional problems, such as vitamin B12, zinc, folate, or iron deficiency.
