How to Heal a Sore in Your Mouth

Inner mouth sores are irritating and painful. Everything from stress to viral infections to a fractured tooth can cause mouth sores, reports the American Dental Association. Depending on the type of sore and its severity, you can provide initial treatment at home. For a generic canker or cold sore, a basic care regime will heal your mouth within two weeks. See your dentist if the sore becomes worse or does not respond to basic treatment after a few weeks.
