How to become an oral health therapist in Australia.
The full pathway to becoming a registered oral health therapist (OHT) in Australia — the Bachelor of Oral Health degree (same as hygienists), AHPRA registration, the combined paediatric + adult restorative scope, and how OHT pay compares to hygienist-only roles.
Step-by-step: how to become a oral health therapist
- 1
Meet university entry requirements
Year 12 with strong English, Maths and a science. ATAR cut-offs typically 70–85. Mature-age pathways available at most schools.
- 2
Enrol in a Bachelor of Oral Health
Same degree as hygienists. Offered by USyd, La Trobe, Griffith, JCU, Charles Sturt, Curtin, UAdelaide. The OHT scope is the paediatric / adolescent restorative endorsement built into the degree.
- 3
Register with AHPRA as both hygienist and OHT
Graduates are eligible to register in both divisions. Maintaining both gives maximum scope flexibility — paediatric restorative + adult preventive — in mixed-practice work.
- 4
Choose your scope mix
Pure hygienist-only metro private practice often pays the highest hourly. OHT mixed-scope is best paid in paeds-heavy practices, school dental services and regional public-sector roles where the restorative scope is fully used.
- 5
Build experience in paediatric and school-based dentistry
School-holiday paeds demand is the strongest annual driver of OHT locum rates. Practices with strong paeds programs routinely pay above advertised hygienist rates to secure OHT cover.

Day in the life
OHT columns run a mix of hygiene appointments (scale, clean, perio) and paediatric restorative (small fillings, fluoride, sealants, behaviour management). In mixed clinics you may move between adult and paeds chairs across the day. School-holiday weeks are routinely paeds-heavy.
It's a good fit if
- You want scope breadth — hygiene plus paediatric restorative
- You enjoy working with children and adolescents
- You want strong public-sector job options (school dental, community health, regional)
- You like geographic flexibility and a strong locum market for school-holiday cover
The hard parts
- 3-year degree + AHPRA registration + ongoing CPD
- Paediatric behaviour management adds emotional load
- Some private practices under-use the OHT scope — pay lift only shows up where paeds restorative is actually booked
Where the career goes from here
Common paths: scope expansion (LA endorsement), specialty paediatric focus, public-sector senior / lead OHT roles, education within Bachelor of Oral Health programs, or moving into hygienist-only metro practice for higher hourly.
Market outlook (2026)
OHTs are underrepresented in private practice relative to demand, particularly in paeds-heavy clinics. Public-sector OHT roles in regional areas remain a reliable entry route with structured progression.
