Mouth Ulcers
What are mouth ulcers?
A mouth ulcer is a painful sore in the mouth on either the cheeks or gums. They usually appear red or yellow in colour. Mouth ulcers occur either singly or in clusters, causing a lot of discomfort or pain.
There are two common causes of mouth ulcers. Accidental damage is responsible for many - brushing your teeth too hard, minor burns from hot food and drinks, biting the inside of the mouth accidentally, a tooth that's become rough, or orthodontic braces or dentures that rub against the gums.
These last for a week or more unless the damage continues happening, in which case they will not disappear until the cause - for example, a rough tooth - is treated.
The other common type is an aphthous ulcer, which occurs when someone's feeling stressed or under the weather. They often appear for the first time during puberty and they can run in families. These can take a couple of weeks to heal and are likely to keep appearing until someone's feeling relaxed and well again.
