Dental Therapist vs Hygienist: Scope, Pay & Differences (UK)

Dental therapist vs dental hygienist: side-by-side comparison

What a dental hygienist does

A dental hygienist is a registered DCP whose clinical scope centres on the prevention and management of periodontal (gum) disease and oral-health promotion. The current GDC Guidance on Scope of Practice (effective 1 November 2025) no longer publishes a fixed task list; instead it describes each title in competency terms and stresses that the registrant must be trained, competent and indemnified for each task (GDC, 2025).

Tasks typically within a dental hygienist’s scope include:

• Removing hard and soft deposits — supra- and sub-gingival scaling and root surface debridement
• Polishing teeth and applying topical fluoride varnish
• Placing fissure sealants
• Taking and processing dental radiographs (subject to IRMER 2017 training)
• Administering local anaesthetic where trained and competent
• Taking impressions and study models
• Delivering oral-health education and preventive advice
• Supplying and administering certain specified medicines under the exemptions mechanism (not prescribing — see below)

A dental hygienist does not place fillings, carry out extractions of any kind, undertake orthodontic treatment, or prescribe medicines.

What a dental therapist does

A dental therapist has a broader clinical scope than a hygienist. A therapist can do everything a hygienist does, and in addition can carry out routine restorative and children’s dental treatment. The additional procedures explicitly within a therapist’s scope include (GDC, 2025):

• Direct restorations (fillings) in both primary (baby) and permanent (adult) teeth
• Extracting deciduous (baby) teeth — therapists do not extract permanent teeth
• Pulpotomies and pre-formed (e.g. stainless-steel) crowns on the primary dentition
• Fissure sealants on both primary and permanent teeth

A dental therapist does not extract permanent teeth, carry out root canal treatment on adult teeth, place indirect restorations (crowns, bridges, veneers), undertake orthodontic procedures, or prescribe medicines. Choice of filling material — including whether dental amalgam is used — is governed by separate mercury legislation, not by GDC scope.

This wider scope is why a therapist’s training programme is longer and more restorative in focus. The two titles share an identical preventive and periodontal scope.

Training routes and qualifications

Both roles require completion of a GDC-approved programme and registration with the GDC before you can practise under the protected title.

Dental hygiene is most commonly entered via a two-year diploma in dental hygiene or a BSc. Some programmes qualify you in hygiene only.

Dental therapy is most commonly entered via a three-year BSc — and, in the UK, many of these are dual-qualification programmes that register you as both a dental hygienist and a dental therapist on graduation. A standalone diploma route also exists. Because so many therapists are dual-qualified, a large share of the workforce holds both titles and can move between preventive, periodontal and restorative work depending on the role.

Entry typically requires science-based qualifications, and competition for places is strong. The GDC-approved pre-registration curriculum is set out in The Safe Practitioner (GDC, 2023), which replaced Preparing for Practice for UK dental education from September 2025.

After qualifying, both titles must register with the GDC and pay the annual retention fee (ARF) for DCPs, complete enhanced CPD, and maintain indemnity. You can check what each title is permitted to do — and confirm your own registered duties — with the free GDC Scope of Practice Checker (linked below).

UK salary ranges (indicative — verify before relying on them)

Pay for hygienists and therapists varies enormously by setting (NHS vs private), location, hours, and whether you are employed on a salary, paid per session, or per hour. Most hygienists and therapists work part-time and/or sessional, so a single "salary" figure is misleading. The ranges below are indicative only and should be checked against current advertised vacancies and pay scales.

Indicative ranges as of June 2026. NHS roles sit on Agenda for Change — Band 5–6 spans roughly £30,300–£46,600 for 2025/26 in England, depending on band, experience and nation (source: NHS Employers / NHS Agenda for Change 2025/26). Private/sessional figures are drawn from live UK job adverts and vary widely. Both titles typically start at Band 5 and can progress to Band 6 (or 7 with specialist/leadership duties); pay tracks the role, not the title.

Always sense-check current figures against live job adverts (NHS Jobs, Indeed, totaljobs), the relevant NHS Agenda for Change pay scales for your nation, and professional bodies such as the British Society of Dental Hygiene and Therapy (BSDHT) and the British Association of Dental Therapists (BADT).

Scope overlap and what only a dentist can do

The two DCP titles overlap completely on prevention and periodontal care. The therapist’s scope simply extends further into routine restorative and children’s treatment. Some procedures remain outside both hygienist and therapist scope and require a dentist (or, for some, a specialist):

• Extracting permanent (adult) teeth
• Root canal treatment on permanent teeth (procedures involving the pulp of the adult dentition)
• Indirect restorations — crowns, bridges and veneers
• Orthodontic treatment
• Prescribing medicines (neither title is an independent or supplementary prescriber)
• Overall diagnosis and treatment planning for complex care, and surgical procedures beyond the listed scope

Holding a title does not, by itself, authorise every task within it: under the GDC’s competency-based approach you must also be trained, competent and indemnified for each specific procedure (GDC, 2025).

Direct access: both roles, since 2013

Since 1 May 2013, both dental hygienists and dental therapists in the UK have been able to see patients without a prescription or referral from a dentist — known as direct access. Direct access does not widen your clinical scope; it only changes how the patient reaches you. A therapist working under direct access still cannot extract an adult tooth, and a hygienist still cannot place a filling.

For a fuller explanation of direct access, the 2025 scope changes, and the medicines-exemptions rules, see our pillar guide on the GDC scope of practice 2025 (linked under Related guides below).

Record-keeping differences

The same GDC and FGDP/CGDent record-keeping standards apply to hygienists, therapists and dentists alike — there is no lower bar for DCPs. The practical difference is what there is to record: a therapist’s notes routinely have to document restorative procedures (tooth, surface, material, batch and expiry of any anaesthetic, consent for the procedure) and paediatric extractions, whereas a hygienist’s notes centre on periodontal indices (BPE, pocket charting, bleeding and plaque scores), prevention and direct-access referral pathways.

For role-specific templates and what each title should capture, see the hygienist and therapist notes templates guide and the full DCP record-keeping standards (UK) — both linked under Related guides below.

Check your registered duties with the GDC Scope tool

Because the GDC’s 2025 guidance is competency-based rather than a fixed list, the safest way to confirm what you may do is to check your registered title against the current guidance and your own verifiable training. Use the free GDC Scope of Practice Checker to look up the duties associated with the dental hygienist and dental therapist titles before taking on any unfamiliar procedure.

How Nosht supports hygienists and therapists

Nosht provides structured clinical-note templates built around DCP workflows — periodontal assessment, root surface debridement, fluoride and sealant application, direct-access intake, restorative procedures (for therapists) and referral documentation — all aligned to GDC and FGDP/CGDent record-keeping standards.

Nosht uses optional, clinician-reviewed AI (Anthropic’s Claude Haiku 4.5) in two narrow ways: it can turn your shorthand into structured note fields that you review and confirm line by line, and it offers an advisory "Bulletproof" check that flags where a note may be incomplete. The template core is deterministic, and the AI is never trained on your notes. Unlike ambient or voice-based AI scribes that record and transcribe the consultation, Nosht’s structured-notes workflow does not record audio — you type shorthand; there is no voice capture in this workflow, and you confirm every field yourself. Templates are designed to exclude patient identifiers, and you copy the finished note into your own practice-management system, which remains your system of record.

Is a dental therapist higher than a hygienist?

No — neither title is "higher" than the other. A dental hygienist and a dental therapist are both GDC-registered dental care professionals of equal professional standing. The difference is scope, not seniority: a therapist has a wider clinical scope (adding routine fillings, baby-tooth extractions and some children’s procedures), while a hygienist focuses on prevention and periodontal care. Many UK clinicians are dual-qualified in both.

Can a hygienist do fillings?

No. Placing direct restorations (fillings) is outside a dental hygienist’s scope of practice. Fillings on both adult and children’s teeth fall within a dental therapist’s scope (or a dentist’s). A dual-qualified clinician registered as both a hygienist and a therapist may place fillings under their therapist title, provided they are trained, competent and indemnified for it (GDC Guidance on Scope of Practice, 2025).

Who earns more, a hygienist or a therapist?

It depends far more on the setting, hours and pay basis than on the title. A therapist employed in a restorative role may command a modest premium for the broader scope, but a dual-qualified clinician working a hygiene-only list is paid as a hygienist. Sessional and private pay can exceed salaried roles but exclude leave and pension. Always check current job adverts and the relevant NHS Agenda for Change scales rather than relying on a single headline figure.

Can a dental therapist extract teeth?

A dental therapist can extract deciduous (baby) teeth only. Extracting permanent (adult) teeth is outside a therapist’s scope and requires a dentist (GDC, 2025).

Do hygienists and therapists need a dentist’s referral to see patients?

No. Since 1 May 2013, both titles can work under direct access — seeing and treating patients within their scope without a dentist’s prescription or referral — provided they refer on when they find something outside their scope and their indemnity covers direct-access practice.
