The two-year rule: how often should you see a dentist?

By Dr Faiz Azizan Data last checked How we list clinics

How often you need a dental check-up depends on your oral health. NICE guidance recommends intervals of between 3 and 24 months for adults and 3 to 12 months for children, set by your dentist according to risk. The 'two-year rule' refers to practices treating long-absent NHS patients as no longer registered.

What the rule referred to

Many NHS practices treat a patient who has not attended for around two years as no longer on their list. Practice policies and NHS guidance on this have changed over time, so check current information with your practice and NHS England.

How often should you go?

NICE recommends that the interval between check-ups is tailored to the individual, based on their risk of dental disease. Someone with healthy teeth and gums and good habits may be advised to wait longer than someone with gum disease or frequent decay.

If you have been removed from a list

You can ask the practice whether it can see you again, or use NHS Find a dentist. For urgent pain, call NHS 111.
