To become a general dentist, a person must graduate from dental school and have either a DDS or a DMD degree:

• DDS. Doctor of dental surgery
• DMD. Doctor of dental medicine

There is no difference between the degrees. Both dentists have the same education. They completed the same curriculum requirements. Some schools award a DMD degree. Others award a DDS degree. To be a general dentist typically requires 3 or more years of undergraduate college education plus 4 years of dental school.

More postgraduate training is needed to become a dental specialist. Specialists work in areas where advanced knowledge, skills, and training are needed. Each specialty is unique, but their goal is the same: to maintain or restore oral health. You may be referred to a dental specialist by your general dentist to make sure that your special dental needs are met with the most advanced treatment possible. The National Commission on Recognition of Dental Specialties currently has 12 dental specialties. These include:

• Pediatric dentist. A pediatric dentist focuses on the oral healthcare of children, from babies through teens. Pediatric dentists often work closely with pediatricians, family healthcare providers, and other dental specialists.
