Black Tongue, Home Treatment

To do home treatment 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 the edge of a spoon to remove the furry coating.
  • Do not use tobacco.

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