Frequently asked questions
What qualifications does a dental hygienist need?
In the UK, dental hygienists must hold a diploma or degree in dental hygiene and be registered with the General Dental Council (GDC). Many roles now prefer candidates with a BSc in Dental Hygiene and Therapy, which provides a broader scope of practice. Continuing professional development is mandatory to maintain registration.
How do you assess clinical skills during a dental hygienist interview?
Ask detailed questions about periodontal assessment, treatment planning and instrument selection. Case study discussions are particularly effective. Some practices arrange a practical assessment where candidates demonstrate scaling technique on a typodont or observe a supervised patient treatment. Clinical competence should be the primary selection criterion.
Should dental hygienists work independently or under direct dentist supervision?
Modern dental hygienists are qualified to work to their own competence under indirect supervision, meaning a dentist does not need to be present for every appointment. This model improves practice efficiency and allows dentists to focus on more complex procedures. However, clear protocols for referral and escalation must be in place.
