Treating a Black or Coated Tongue

Skip to the navigation

Topic Overview

Home treatment may be all that is needed for a black or coated tongue.

  • Brush your tongue daily with a soft-bristled toothbrush and toothpaste or a solution of 1 part hydrogen peroxide to 2 parts water.
  • Scrape the tongue with an upside-down teaspoon to remove the "furry" coating on the tongue.
  • Do not use tobacco products.

Bismuth products, such as Pepto-Bismol, can turn your tongue black. The black appearance will go away after you stop taking the medicine.
