- Mouth Ulcers
Mouth ulcers are painful round or oval sores that form in the mouth, most often on the inside of the cheeks or lips. Although they are normally harmless, mouth ulcers can be uncomfortable, especially when irritated by things like food and drink. They will normally clear up on their own in about a week or so, but you can relieve the pain with an over the counter mouth ulcer remedy so there's no need to suffer. Some mouth ulcer treatments coat the ulcer to create optimum healing conditions, enabling it to heal quicker, as well as providing relief from the pain.
