Oral cancer screenings are a very important part of the dental visit for the patient. The ability to do so is extremely important in being able to treat any issues prior to them becoming a major irreversible problem. It is very important to pinpoint the start of a potential problem much earlier in its evolution. Certain lifestyle choices can have a great impact on the health of tissues and your overall health in the mouth. If you are a smoker or heavy drinker, make sure to get regular screenings when you visit the dentist.
