What can be done for a hairy tongue?

Brush your tongue: Hairy tongue is caused by the lengthening of papillae which are bumps on the surface of the tongue. It is also a side effect while taking the antibiotic penicillin. Hairy tongue does not involve any type of bacteria or fungi and generally resolves on its own; the recommended treatment is to brush the tongue with a soft toothbrush twice per day.

Brush: Hairy tongue is typically treated with debridement or simple brushing. Try brushing the tongue two to three times a day with a soft bristle toothbrush.

Tongue scraper: Clean your tongue with a tongue scraper, do not rinse with peroxide.
