Interview tips for this role
- Verify their dental nursing qualifications and GDC registration before the interview.
- Ask them to describe specific procedures in detail. Genuine experience shows in the terminology and sequence.

Frequently asked questions
What qualifications does a dental assistant need in the UK?
In the UK, dental nurses must hold a recognised qualification such as the NEBDN National Diploma in Dental Nursing and be registered with the General Dental Council. They must also complete continuing professional development hours each cycle. Verify registration status before hiring.
How do I assess clinical competence in an interview?
Ask candidates to walk through specific procedures step by step, including instrument preparation, suction technique and post-treatment protocols. Practical assessments or trial shifts are the most reliable way to evaluate chairside skills beyond what an interview reveals.
What is the biggest challenge in hiring dental assistants?
Retention is often the biggest challenge. The role is physically demanding with relatively modest pay. Focus on candidates who show genuine passion for patient care rather than those treating it as a stepping stone. Discuss career development opportunities during the interview to attract committed candidates.
