What Is the Role of an Oral Health Therapist

Who Are Oral Health Therapists?

A modern dental clinic provides care through a team of trained professionals, each with specific expertise to ensure comprehensive treatment.

A professional dental team may include:

  • Dentists and paediatric dentists
  • Dental hygienists
  • Dental prosthetists
  • Dental therapists
  • Oral health therapists (OHTs)

This page explains the qualifications, responsibilities, and importance of an oral health therapist within a dental practice.

What Is the Role of an Oral Health Therapist?

An oral health therapist is a registered primary healthcare professional who has completed formal education in both dental hygiene and dental therapy.

Because of this dual qualification, an oral health therapist combines the skills of a dental hygienist and a dental therapist.

Their primary focus is promoting oral health and preventing dental disease across all age groups, including children and adults.

What Does an Oral Health Therapist Do?

Oral health therapists work collaboratively within a dental team to provide efficient, patient-focused care. When a dental issue falls outside their scope of practice, they will refer the patient to a dentist for further assessment or treatment.

Oral health therapists typically provide:

  • Primary dental healthcare
  • Routine dental treatments such as fillings, professional cleaning, and polishing
  • Comprehensive dental examinations
  • Preventive treatments including fluoride applications and fissure sealants
  • Oral hygiene education
  • Dietary counselling
  • Diagnosis of common dental conditions and treatment recommendations

Clinical Responsibilities of an Oral Health Therapist

An oral health therapist may:

  • Examine teeth for early signs of decay
  • Assess gum health and detect periodontal disease
  • Provide preventive strategies to control oral disease
  • Improve a patient’s oral hygiene prior to complex procedures
  • Take dental X-rays
  • Perform baby tooth extractions under local anaesthetic
  • Replace gauze after extractions
  • Place crowns on primary (baby) teeth
  • Take impressions for mouthguards
  • Deliver oral health education to schools
  • Encourage healthy eating habits in school settings
  • Promote positive oral hygiene practices at home and in educational environments

Education is a major part of an oral health therapist’s role. They guide patients on maintaining strong oral health through proper brushing, flossing, and preventive care.

Dental Therapists vs Dental Hygienists

Understanding the difference between dental hygienists and dental therapists can help clarify the broader role of oral health therapists.

Dental Hygienists

Dental hygienists specialise in preventive dental care. Their duties include:

  • Professional teeth cleaning
  • Scaling to remove plaque and tartar
  • Fluoride treatments
  • Fissure sealants
  • Educating patients on oral hygiene.

They play a vital role in preventing gum disease and managing halitosis (bad breath). Hygienists may also assist in hospital settings for patients undergoing procedures under general anaesthesia.

Dental Therapists

Dental therapists are trained to perform all hygienist duties, along with additional restorative treatments such as:

  • Filling cavities
  • Managing dental decay in children
  • Placing or removing caps on baby teeth.

This extended scope allows them to provide more comprehensive care, particularly for younger patients.

Is It Worth Seeing an Oral Health Therapist?

Absolutely. Visiting an oral health therapist regularly, alongside daily brushing and flossing, helps maintain optimal oral health and detect potential issues early.

Preventive care reduces the likelihood of more complex dental treatments in the future and supports long-term oral wellbeing.
