  • Mouth ulcers are usually painful, but oral cancer is not.
  • Mouth ulcers go away in about two weeks, while oral cancer doesn’t go away and often spreads.
  • Oral cancer patches can be rough, complex, and difficult to scratch.
  • Oral cancer is usually a mixture of red and white or large white areas on the tongue, back of the mouth, gums, or cheeks.

In many cases, the pain and discomfort of a mouth ulcer will go away within a few days and then go away in about two weeks without the need for any treatment.

A dentist may prescribe a solution to decrease swelling and relieve pain for people with much more painful or recurrent canker sores.

Additionally, a dentist may prescribe an antimicrobial mouthwash or ointment applied directly to the infected patch. This can help relieve discomfort. Various canker sores treatments are also available online.

Types Of Mouth Ulcer

Types Of Mouth Ulcer

Conventional sores appear on the inside of the cheeks and last about one week. Most are harmless and go away without medical intervention.

There Are Three Main Types Of Mouth Ulcers. These include:

Herpetiform Ulcer (HU)

Herpetiform ulcers are a subtype of canker sores and get their name because they resemble the sores associated with herpes. Unlike herpes, HU is not contagious. However, HU ulcers recur very quickly, and the condition never seems to improve.

minor ulcers

This type can range from about 2 millimetres (mm) to 8 mm in width. These sores usually take up to 2 weeks to heal and cause mild pain.

major ulcers

Larger ulcers are often irregular in shape, may protrude, and penetrate deeper than more minor ulcers. They can take some weeks to go away and leave behind scar tissue as they go away.


Ulcers can be sore, and the pain can be made poorer by eating, drinking, and poor oral hygiene.

HU injuries can:

  • appear as excruciating mouth ulcers
  • reproduce very quickly, so infections occur continuously
  • increase in size and eventually merge into a large irregular ulcer
  • take ten or more days to heal
  • appear anywhere in the mouth
