Just like Dentists, Oral Health Therapists ("OHT") are also registered dental practitioners. They must be registered with the Australian Dental Board and the Australian Health Practitioners Regulation Agency (AHPRA). AHPRA has strict requirements for registered dental professionals, including annual compulsory professional development to ensure that your dentist and OHT are current with advances in science and dental practice.
OHT's need to complete a 3-year degree to qualify in two important roles: as a Dental Therapist and as a Dental Hygienist. This means they can provide treatment advice, diagnosis, and preventive programs for the oral health of children and adults.
