Oral cancer screening is non-invasive and painless. Your dentist just checks your mouth for any signs of oral cancer and asks you for any symptoms you may have. Since oral cancer includes cancers of the neck, throat, tongue and lips, the dentist will do his best to inspect these areas to ensure that all appearances are normal.
Adults over the age of 18 recommend annual screening, so unless you have symptoms or you are a tobacco user, this procedure will only occur once a year. If you use tobacco, your dentist may want to screen more often and may check every six months.
