Answer 1

i suffer from mouth ulcers regulary. it is known to occur when you are run down. Eat a balanced diet and get plenty of sleep at least 7 hours a night. To get rid of them rinse your mouth with salt water

Answer 2

Mouth ulcers are caused when something irritates your mouth, either you bite your lip, something rubs against your gum or somehting you eat irritates your mouth. I get them really badly sometimes. Sugary food and drinks seems to make them worse.
the best thing I ever did was stop using normal toothpaste. I read that if you avoid sodium laurel sulphate (the ingredient which makes soaps/ toothpaste/ washing up liquid froth up) that helps a lot. So now I use sensodyne gel toothpaste. I hardly ever get ulcers now.

The exact cause of mouth ulcers is unknown, but in some cases they are thought to be caused by an overreaction by the body's own immune system. Factors that appear to provoke them include stress, fatigue, illness, injury from accidental biting, hormonal changes, menstruation, sudden weight loss, food allergies and deficiencies in vitamin B12, iron and folic acid. Some drugs, such as nicorandil, have been linked with mouth ulcers.
Mouth ulcers are thought to form when the body becomes aware of and attacks chemicals which it does not recognize. The presence of the unrecognized molecules garners a reaction by the lymphocytes, which trigger a reaction that causes the damage of a mouth ulcer.
Trauma to the mouth is a common cause of mouth ulcers. Physical trauma, such as toothbrush abrasion, poking with sharp food, accidental biting (this can be particularly common with sharp canine teeth), or dental braces can cause mouth ulcers by breaking the mucous membrane. Other factors, such as chemical irritants or thermal injury, may also lead to the development of ulcers. However in many cases, the precise cause is unknown.
A common cause of ulcers is gluten intolerance, in which case consumption of wheat, rye, or barley can result in chronic mouth ulcers. If gluten intolerance is the cause, prevention means taking most breads, pastas, cakes, pies, cookies, scones, biscuits, beers etc. out of the diet and substituting gluten-free varieties where available. Artificial sugars, such as those found in diet cola and sugarless gum, have been reported as causes of mouth ulcers as well. They can also be linked to an increased intake of acids such as ascorbic acid (one form of Vitamin C) or citric acid. In this case the sores disappear after intake decreases (for example, by substituting ascorbate salts for ascorbic acid).
