A General Dentist provides all your normal and routine dental services such as semi-annual cleanings and exams, x-rays, filling cavities, etc... A General Dentist can be thought of in the same way you think about your General Doctor or Family Doctor. If you have a dental problem, you should always visit your General Dentist first. If there is a more serious problem he or she can not remedy, your General Dentist will refer you to a specialist.
There are various types of Dental Specialists such as Orthodontists, Periodontists, Cosmetic Dentists and Oral Surgeons. For descriptions of each of these and what they do, see the FAQ about each one.
