The grit in snuff eats away at gums, exposing tooth roots which are sensitive to hot and cold temperatures and can be painful. Sugar in spit tobacco causes decay. Spit tobacco users also have a hard time getting their teeth clean. Red sores are also a warning sign of cancer. Often, signs of precancerous lesions are undetectable.
Dentists can diagnose and treat such cases before the condition develops into oral cancer.
If a white or red sore appears and doesn't heal, see your dentist immediately for a test to see if it's precancerous. Spit tobacco users also should see their dentist every three months, to make sure a problem doesn't develop. Studies have found that 60 to 78 percent of spit tobacco users have oral lesions. Double dippers, who mix snuff and chewing tobacco, are more likely to develop precancerous lesions than those who use only one type of spit tobacco. Your dentist can help you kick your spit tobacco habit.
