If you would like to prevent everyone from having cavities and pull out those aching teeth, you must hold a degree of Doctor of Dental Surgery. You will have eight years of college and dental school to complete for this degree.
Find a school by contacting the American Dental association and then prepare to take the Dental Admissions Test. Your scores will determine whether or not you will be accepted in to an accredited school of dentistry. If accepted, you will spend the first two years in class and labs and then you will spend the last couple of years practicing under supervision.
