Treatment for sores, particularly canker sores found on the tongue's surface, involve taking over-the-counter medications, applying topical medications and using a prescription mouth rinse. As of 2015, a cure for canker sores remains unknown, states WebMD.
Canker sores, which are normally found inside the oral cavity, typically resolve within a short period of time. For a more bothersome condition, a doctor may prescribe a mouth rinse with the active ingredient steroid dexamethasone. Direct application of topical products containing benzocaine, fluocinonide and hydrogen peroxide can also help treat canker sores, notes Mayo Clinic.
Non-prescription medications, such as acetaminophen, aspirin, ibuprofen are recommended for canker sores on the tongue. Solutions containing carbamide peroxide not only diminish pain but also disinfect the sores through anti-bacterial action. Under the guidance of a physician, the use of silver nitrate and debacterol can also aid in the healing process of canker sores, suggests TheraBreath.
