If your booking says you will be seeing an oral health therapist rather than a dentist, you are seeing a registered dental practitioner who is accountable for their own clinical decisions. In Australia there is no fixed list of procedures an oral health therapist may perform. The Dental Board of Australia instead requires every dental practitioner to do only the treatment they have been educated and trained in and are competent to carry out, and to refer when care goes beyond that.
If your question is simply who cleans teeth and who repairs them, our comparison of a dental hygienist and a dentist is the place to start. This article goes further into how an oral health therapist's scope works and what it means when you book.
One degree, two professions
Oral health therapy brings together two older dental professions. Dental hygiene centres on the gums and supporting bone: assessing gum health, removing hardened deposits above and below the gum line, and keeping treated gum disease stable over time. Dental therapy grew out of school dental services and centres on prevention and fillings, especially for children, including fluoride, fissure sealants and removing baby teeth.
Australian universities now teach both in a single oral health degree. Graduates register with the Dental Board of Australia in the oral health therapist division and appear on the same public register as dentists, dental prosthetists, hygienists and therapists. Like every dental practitioner, they must meet registration standards covering continuing professional development, recency of practice and professional indemnity insurance.
Some practitioners are registered only as a dental hygienist or only as a dental therapist, often because they trained before combined degrees were common. That is fully legitimate. Their scope reflects their own training.
The titles are protected under national law. Someone who is not registered cannot call themselves a dental therapist or oral health therapist, just as they cannot call themselves a dentist. The public register shows each practitioner's division and whether any conditions apply to their registration.
Scope follows training, not a procedure list
The Dental Board's scope of practice registration standard, in effect since 1 July 2020, states that dental practitioners must only perform dental treatment for which they have been educated and trained and in which they are competent. The Board's published answers to common questions about the revised standard describe the key change as the removal of the regulatory requirement for hygienists, dental therapists and oral health therapists to work within a structured professional relationship with a dentist.
The same guidance makes two points worth knowing. First, all dental practitioners must refer a patient when the care needed is outside their own scope. Second, removing that requirement is not the same as saying these practitioners work alone. Most oral health therapists still work within a dental team, and individual practices may have their own protocols about when a dentist is involved.
For patients, this has two practical effects. An oral health therapist answers to the Board for their own decisions, as a dentist does. And because scope depends on each person's training, two oral health therapists can legitimately offer slightly different services.
Gum care and prevention make up most of the work
On the periodontal side, an oral health therapist measures and records gum pockets, removes deposits above and below the gum line, carries out deeper cleaning of root surfaces for people with established gum disease, and runs the maintenance visits that keep it under control. If you have ever wondered about the numbers read out during that measuring, our explanation of periodontal charting numbers is worth a look before your next visit.
Prevention includes fissure sealants, fluoride treatments, advice on diet and habits, support for quitting smoking, and cleaning instruction tailored to your mouth. This sounds modest, but helping someone find a way of cleaning between their teeth that they will actually keep up can matter more over the long run than many individual procedures.
Working with children is a skill in its own right. Helping a nervous young child through a first filling calmly is something dental therapy training specifically prepares people for, and it is one reason practices often book young or anxious patients with an oral health therapist.
Restorative work includes fillings in baby teeth and removing baby teeth. Many oral health therapists also place straightforward fillings in adult teeth where their training covers it. Whether a particular practitioner does adult fillings depends on their degree, any further training and the practice they work in.
X-rays are part of many examinations. Taking them requires meeting state or territory radiation licensing rules, which are separate from Dental Board registration.
Adults, children and the age question
A common belief is that oral health therapists only see children. The hygiene side of the role has always included adults, and an oral health therapist may see a young child for sealants and an older adult for gum maintenance on the same day.
For fillings and other restorative care, the answer depends on training. The Dental Board's guidance notes that a practitioner whose training was limited to patients up to 18 is unlikely to gain the competence to treat patients of any age through continuing professional development alone. So the useful question is not how old the patient is, but whether that practitioner has been trained for the care that patient needs.
Children's care is also supported by public funding. Eligible children aged 0 to 17 can receive basic dental services under the Child Dental Benefits Schedule, with a benefit cap of $1,158 over two calendar years in 2026. The scheme does not cover orthodontics or cosmetic work. Our guide to how the Child Dental Benefits Schedule works explains eligibility.
Care that usually needs a dentist
Treatment planning for complex cases, crowns, bridges, veneers and other lab-made restorations, root canal treatment, removal of adult teeth, oral surgery, implants and most cosmetic dentistry fall to a dentist. So does care for medically complex patients and anything involving prescribing or sedation. Lumi does not provide general anaesthetic; for patients who need extra help to get through treatment, we offer happy gas (relative analgesia), inhaled pain relief, oral sedation and IV sedation.
Referral is a routine part of good care. Gum disease that is advanced or not responding may be referred to a periodontist, a difficult surgical extraction to an oral surgeon, and complex children's care to a paediatric dentist. Our overview of the dental specialties explains who does what.

| Fillings and removal of baby teeth | Yes, core work | Yes |
| Straightforward fillings in adult teeth | Depends on training | Yes |
| Crowns, bridges and veneers | No | Yes |
| Root canal treatment | No | Yes |
| Adult extractions and surgery | No | Yes |
| Implant placement | No, though they often help maintain implants | Yes |
Why the hygiene visit takes longer than you expect
A visit with an oral health therapist is rarely just a polish. It usually includes a soft tissue check, gum measurements, a comparison with your last visit, the cleaning itself, and a conversation about what to adjust at home. Gum disease is controlled rather than cured, and what happens between visits often decides whether it stays stable. Our guide to what happens at a scale and clean walks through each step.
A routine clean and periodontal maintenance are not the same appointment. Maintenance visits are longer, more frequent and focus on sites with a history of bone loss. If your gums never seem to settle, it is worth asking which one you are booked for; our comparison of periodontal maintenance and a regular clean explains the difference.
Tips for booking
In a team practice, the examination with a dentist and the hygiene visit with an oral health therapist may be separate appointments, or they may be combined, particularly for new patients. Either can work well. It helps to ask when you book whether the visit is an examination, a routine clean or a maintenance visit, so the right amount of time is set aside.
Continuity helps too. Gum care relies on spotting change, and a practitioner who has seen your mouth before is better placed to notice that a measurement has moved. Being honest about what you really do at home also helps the plan fit your life.
Oral health therapists at Lumi
Our oral health therapists, Sabrina Tran and Jennifer Nguyen, see children, adults and families, with a focus on prevention and gum health. They work alongside our dentists, so if something needs a dentist's opinion, it can usually be arranged within the same practice. Eligible children are bulk billed under the Child Dental Benefits Schedule.
Lumi is open Monday to Saturday, with late appointments on Thursday and Sunday visits by appointment. When you book, reception can tell you who you will be seeing: a dentist, an oral health therapist or both. New patient information is on our current offers page.
