All About Dentistry

Dentists: Doctors of Oral Health

imageMost Americans today enjoy excellent oral health and are keeping their natural teeth throughout their lives. But this is not the case for everyone. Cavities are still the most prevalent chronic disease of childhood. Further, about 100 million Americans did not see a dentist in 2007, even though regular dental examinations and good oral hygiene can prevent most dental disease.

Too many people mistakenly believe that they need to see a dentist only if they are in pain or think something is wrong, but they're missing the bigger picture. A dental visit means being examined by a doctor of oral health capable of diagnosing and treating conditions that can range from routine to extremely complex.

The American Dental Association believes that a better understanding of the intensive academic and clinical education that dentists undergo, their role in delivering oral health care and, most important, the degree to which dental disease is almost entirely preventable is essential to ensuring that more Americans enjoy the lifelong benefits of good oral health.

Confused about DDS and DMD?

DDS - doctor of dental surgery
DMD - doctor of dental medicine

These both indicate the degree awarded upon graduation from dental school to become a dentist. There is no difference between the two degrees; dentists who have a DMD or DDS have the same education.

Universities have the prerogative to determine what degree is awarded. Both degrees use the same curriculum requirements set by the American Dental Association's Commission on Dental Accreditation. Generally, three or more years of undergraduate education plus four years of dental school is required to graduate and become a dentist. Additional post-graduate training is required to become a dental specialist, such as an orthodontist, periodontist or oral and maxillofacial surgeon.
