How to heal tongue sores

Updated April 17, 2017

Injuries to the tongue are extremely uncomfortable. They can also interfere with eating, talking and smiling. Tongue sores are small ulcers caused by a number of factors including hot foods, accidental biting, viral infections or allergies. Most tongue sores will heal on their own within a few weeks; however the pain can be uncomfortable in the interim. Treating tongue sores using simple remedies can alleviate the discomfort.

Mix the salt and water until the salt is completely dissolved. Take a mouthful of the saltwater and swish and gargle it for one minute. Spit and repeat at least three times each day until the sores diminish.

Create a paste by mixing the baking soda and water together. Dab the paste onto the sores using a cotton swab. Allow the paste to remain in place for at least five minutes.

Rinse your mouth using antimicrobial mouthwash three times daily until the sores heal. The mouthwash will disinfect the area, keeping the sores clean and permitting them to heal faster.

Soak a cotton swab in hydrogen peroxide. Press the cotton swab onto your tongue sores. Try to use this technique in the earliest stages of the sore's development as the peroxide will impede growth.


Visit your doctor before pursuing any alternative treatments. Sores may be an indication of a more serious infection or condition.
