An orthodontist is a dentist trained to diagnose, prevent, and treat teeth and jaw irregularities. They correct existing conditions and are trained to identify problems that may develop in the future. Orthodontists work with people of all ages, from children to adults.
Endodontists are dentists who specialize in tooth pain, disease, and infection. They have extra training that helps them diagnose and treat tooth pain and perform root canals, a special procedure designed to save an infected or decayed tooth.
