Many mouth ulcers will go away on their own without treatment. Some measures to speed the healing process include the following:
The healthcare provider may prescribe a liquid paint, mouthwash, gel, or rinse to treat the mouth ulcer.
Rarely, medications used to treat mouth ulcers may cause an allergic reaction.
Mouth ulcers usually go away on their own or with treatment. If the underlying cause of the ulcers is not treated, they may recur. A person with recurring mouth ulcers should see a healthcare professional for further diagnosis.
Any new or worsening symptoms should be reported to the healthcare provider.
