What an Oral Health Therapist Actually Does — and Why It Matters for Your Gums

An oral health therapist is a registered dental practitioner in their own right, registered with the Dental Board of Australia through AHPRA, and is not a dentist. An oral health therapist holds a university qualification combining dental hygiene and dental therapy, and practises within a defined scope. The title "Dr" is not used, because an oral health therapist is not a dentist and is not a type of dentist.

That is not a smaller job. It is a different one. At Berala Dental, oral health therapists carry out the periodontal treatment, the cleans, the preventive work and most of the children's care.

If you are not sure who you are booked with or what your appointment will cover, it is a fair question to ask.

What is an oral health therapist?

An oral health therapist completes a university degree in oral health that combines two fields: dental hygiene and dental therapy.

Registration is held with the Dental Board of Australia through AHPRA, under the same National Law that regulates dentists. That carries the same obligations — continuing professional development, recency of practice, professional indemnity insurance, and a published code of conduct.

What differs is scope of practice. A dentist diagnoses and carries out restorative, surgical and prosthetic treatment. An oral health therapist works across periodontal care, prevention and children's dentistry. Neither role is a junior version of the other. They overlap in some places and not in others.

Why the title "Dr" is not used

Because it would be inaccurate. Dentists hold dental registration. Oral health therapists hold oral health therapy registration. Both are registered dental practitioners regulated through AHPRA, and the two titles are not interchangeable.

Any practitioner's registration and division can be checked on the AHPRA public register, searchable by name.

What does an oral health therapist actually do?

The scope covers considerably more than a polish. In a general dental practice it usually includes:

• Periodontal assessment and charting — measuring pocket depths, recession, bleeding points and tooth mobility around every tooth, and recording them so change can be tracked over time. What periodontal charting measures explains the numbers.
• Scaling and root debridement — removing plaque and hardened calculus from above and below the gum line, including the root surfaces inside a pocket.
• Non-surgical periodontal treatment — the staged course of treatment used to bring gum disease under control.
• Preventive care — fluoride application, fissure sealants, and assessment of decay and gum disease risk.
• Oral health education — the brushing technique, interdental cleaning and habit changes that largely decide whether treatment holds.
• Children's dental care — examinations, cleans, preventive treatment and much of the treatment children need.

Why children's care sits here

Dental therapy training is specifically oriented to treating children. That is a deliberate part of the qualification rather than an incidental one, which is why oral health therapists deliver most of the children's care at this practice. The paediatric dentistry hub sets out what that covers.

How do the oral health therapist and the dentist work together?

On the same patient, routinely.

The dentist diagnoses and carries out the restorative, surgical and prosthetic work: fillings in adults, root canal treatment, crowns, extractions and dentures. The oral health therapist carries out the periodontal and preventive side, and much of the children's treatment.

Referral runs in both directions inside the one practice. If an oral health therapist finds decay under a filling margin during a clean, or a tooth that is not responding as expected, the patient is seen by a dentist. If a dentist finds bleeding on probing, deep pockets or bone loss on a radiograph, the patient is booked with the oral health therapist for periodontal treatment.

Notes, charts and images sit in the same file, so nobody starts from scratch. It is one plan with two clinicians, not two separate opinions.

If a deep clean has been recommended and you would like to understand what is being treated before you commit to it, the clinical team will talk it through with you.

Why does this matter for your gums specifically?

Because periodontal treatment is the oral health therapist's core training rather than something fitted in between other appointments.

That has two practical consequences for a patient having gum treatment.

Longer, dedicated appointments

Treating periodontal disease is slow, methodical work. Root surfaces have to be debrided section by section, under local anaesthetic where that is appropriate, and the time it takes is the time it takes. When those visits are booked as periodontal appointments in their own right, the work is more likely to be completed properly rather than partially.

Continuity of the same clinician

Gum treatment is a course rather than a single visit: an initial phase, then a review at three months, then maintenance. Seeing the same clinician across it matters, because that clinician remembers which sites bled last time, which pocket measured seven millimetres, and which tooth is the one to watch. Why periodontal maintenance runs every three months covers the timing and the reasoning.

Do you need a specialist to treat gum disease?

A periodontist is a registered specialist who has completed further postgraduate training in the gums and the supporting bone, and who holds specialist registration through AHPRA. Berala Dental is a general dental practice with no specialist on site, and refers where a case genuinely needs one.

The belief that only a specialist can treat gum disease is worth dismantling. Specialists are excellent, and there are cases that only they should handle. But oral health therapists and dentists are trained to treat most cases of periodontal disease, and most cases are treated in general practice.

Referral is a judgement about the case rather than a number. It generally follows around twelve months without stabilisation, or comes sooner if the disease is clearly progressing. Severe presentations are referred immediately. It is not triggered by reaching a particular pocket depth. Do you need a periodontist? goes through that in more detail.

The question is never who is better. It is who is right for your case.

What does gum treatment cost here?

A check-up with X-rays and a clean is $250. The initial phase of periodontal deep cleaning is $1,400 to $1,600, depending on how much of the mouth is involved. Three-monthly periodontal maintenance after that is $400.

Those figures assume no health-fund contribution. A fund may contribute, and what it contributes depends entirely on your policy, so it is worth checking with your fund directly. A written quotation is given before any treatment begins.

Periodontal charting is included within the deep clean rather than charged as an extra. There is more on deep cleaning and on general dentistry.

Quick answers

Is an oral health therapist a dentist?

No. An oral health therapist is a separately registered dental practitioner with a different scope of practice. Both are registered through AHPRA, but an oral health therapist is not a dentist and does not use the title "Dr".

Can an oral health therapist do fillings?

Scope varies with the practitioner's qualification and the practice. At Berala Dental, restorative work in adults is carried out by the dentists, while oral health therapists cover periodontal treatment, prevention and children's care.

Will I see the same clinician for every visit?

For a course of periodontal treatment, continuity is the aim, and appointments are booked with the same clinician wherever scheduling allows. It makes the record more useful and the comparison between visits more reliable.

How do I check who is treating me?

Ask at the practice, and look the practitioner up on the AHPRA public register, which lists every registered dental practitioner in Australia and the division they are registered in. The Australian Dental Association also publishes general information about dental roles.

Where to start

If it has been a while, the sensible first step is an assessment rather than a guess. A first visit at this practice is explained on the new patients page, and the treatment itself is set out under deep cleaning and general dentistry. If you want the background on gum treatment before you book, start with what periodontal charting measures.

If your gums bleed when you brush, that is worth having looked at rather than waiting to see whether it settles.
