Mouth Ulcers

Ever woken up to a break or slight cut on the inside of your lips or the inside of your mouth? These cuts or sores are called mouth ulcers.

Mouth ulcers are sores that appear in the mouth, often on the inside of the cheeks. Mouth ulcers are also known as aphthous ulcers or canker sores. There are three types of mouth ulcers or canker sores and they include;

  1. The Minor– Minor canker sores are also known as “traumatic ulcers”. They are usually small, painful lesions that develop in your mouth or at the base of your gums. These ones are sometimes caused by brushing or biting the cheek and they heal within a week or two with no scarring.
  2. The Major- These are the type of mouth ulcers that are usually deeper and larger than the minor ones, they have irregular edges and can take few weeks to heal. The major mouth ulcers can result in scarring for a period of time.
