Supportive care: Canker sores are either related to a healing spot of damaged tissue (eg, tooth bite) or a viral reactivation. Supportive care is all that is required, such as oral salt water rinses. It may take 2 weeks to heal. If concern for herpetic viral reactivation, then a prescription of antiviral medication, such as valcyclovir, may help.

Throat sore: The common canker sore in the mouth is usually due to common viruses or stress. If you smoke or chew tobacco what may appear to be a canker sore may indicate oral cancer. A lesion in the back of the throat, however, usually indicates something more systemic than local and more serious. You should go see a doctor and be examined.

Time: No magic bullet but topical antibiotic or table salt may possibly be helpful for some. Unlike cold sores, there is little evidence to suggest that this is caused by a viral infection.
