What's the job really like?
Dental hygienist video
Deb Pratt talks about what it’s like to be a dental hygienist - 1.28 mins.
Communication would be as important if not more important than our own technical skills. It’s about building trust with your clients and a good rapport so they’re happy to come back and see you so we can keep their oral health maintained and in a good healthy status.
People will often ask 'Oh my goodness, how can you look in somebody’s mouth all day long?' Somebody comes in with a mouth that is just really unhealthy, and they can see the changes and they can appreciate the health that they’ve achieved and keep them on a good healthy path, then we’re just creating health.
If you think you might be interested in dental hygiene as a career I would say visit your favourite dentist or your dental therapist at school. See if you can hang out there for the day or afternoon and have a good look around and follow the hygienist and see if it’s something you might be interested in.
I do absolutely love my job and look forward to coming to work every day, and it’s the clients that come in and the personal relationships we make here.

What are the chances of getting a job?
Oral health therapist opportunities growing as more people require dental care
Demand for oral health therapists is growing because:
- more people are becoming aware of the importance of preventive dental care
- the ageing population and a rise in cases of obesity and diabetes mean more people need dental care
- the dental therapist and hygienist workforce (which makes up part of the oral health therapist workforce) is ageing.
Number of dental therapists and hygienists declining as more oral health therapists graduate
In 2007, two oral health therapy degrees were introduced, replacing the old dental hygienist and dental therapist qualifications. As more people graduate with the new qualifications, the number of oral health therapists will grow, while the number of dental therapists and hygienists will decline.
According to the Census, 1,116 oral health therapists worked in New Zealand in 2018.
Oral health therapists work for other dental professionals or have their own practice
Most oral health therapists work for:
- school and community dental services.
- dentists who do general dental work
- dental specialists such as periodontists (who prevent, diagnose and treat gum disease) or orthodontists (who prevent, diagnose and treat misalignments of the teeth and jaw).
Some also set up their own private practices, and may contract out their services to a dentist.
