Medically reviewed by Last updated on May 1, 2023.


Smokeless tobacco keratosis

is a condition that causes thick white patches to form on skin in your mouth. Your skin may also be wrinkled or look like leather. The patches form where you hold smokeless tobacco in your mouth. Examples include your inner cheek and between your teeth and gums. Chewing tobacco, snuff, and dipping tobacco (dip) can all cause this condition. Smokeless tobacco keratosis is also called tobacco pouch keratosis or snuff dipper's lesion. Treatment for this condition is to stop using smokeless tobacco. The patches should go away within about a month after you stop. If they do not go away, see your dental provider right away. Smokeless tobacco keratosis slightly increases your risk for oral cancer.

Contact your healthcare provider if:

  • You have new or worsening sores in your mouth, or other symptoms develop.
  • You have questions or concerns about your condition or care.


  • Do not smoke, and do not use smokeless tobacco products. Tobacco and nicotine products can also increase your risk for other health conditions, such as lung and heart disease. E-cigarettes and similar products still contain nicotine. Ask your healthcare provider for information if you need help to quit smoking or using nicotine products.
  • Visit your dental provider every 6 months for cleaning and preventive care. Your provider will also check for signs of oral cancer.
