Chewing
tobacco scratches and stains your teeth, and can cause decay.
Because chewing tobacco contains high concentrations of cancer-causing
agents, chewing tobacco puts you at risk for cancer of the mouth and the
throat.
If
you have been chewing for a long time, watch for the following danger
signs:
- a
mouth sore that doesn't heal
- a
lump or white patch inside your mouth
- chronic
sore throat
- difficulty
in chewing or moving the tongue or jaws
