Treatment may depend on the cause of the mouth sore.

  • A topical anesthetic (applied to the skin) such as lidocaine or xylocaine may be used to relieve pain (but should be avoided in children).
  • An antifungal medication may be prescribed for oral thrush (a yeast infection).
  • An antiviral medication may be prescribed for herpes sores (although some experts don't believe medication will make the sores go away sooner)
  • Anti-inflammatory medications may be prescribed for severe or persistent canker sores.
