Medical review: Based on peer-reviewed research and guidelines. Clinical review by a Dalian Speciality Dental Clinic dentist is pending. This page is general information, not a diagnosis. Please see a dentist about your own teeth.
What the guidance says
The National Institute for Health and Care Excellence (NICE) guideline on dental check-ups says the interval between check-ups should be decided for each patient, based on an assessment of their disease levels and risk.
- For people under 18, the longest interval is 12 months.
- For people aged 18 and over, the longest interval is 24 months.
- Intervals are set between 3 and 12 months for children, and between 3 and 24 months for adults.
- A routine recall of less than 3 months is not normally needed.
- If your dentist finds you are at low risk, the interval can gradually be extended.
What affects your risk?
Your dentist will consider how healthy your teeth and gums are, your history of decay and gum disease, your diet and sugar intake, whether you use tobacco, and your oral hygiene. People with higher risk, such as those with gum disease or frequent decay, benefit from more frequent visits.
What happens at a check-up?
Your dentist examines your teeth, gums and mouth, may take X-rays if needed, talks to you about your cleaning, diet and habits, and advises when to return. Professional cleaning removes tartar that brushing cannot.
Between visits
Brush twice a day with fluoride toothpaste, clean between your teeth and limit sugar. See our article on brushing and preventing cavities.
When to see a dentist
Do not wait for your next check-up if you have tooth pain, bleeding gums, swelling, a broken tooth or a sore that does not heal.
Frequently asked questions
Do I really need to go every six months?
Not necessarily. Guidance says the interval should be set for you, based on your risk. Ask your dentist how often is right for you.
Can I go less often if my teeth are healthy?
For low-risk adults, intervals can be extended up to 24 months under NICE guidance, but your dentist should make that decision with you.
Do children need more frequent visits?
The longest recommended interval for under-18s is 12 months, and children at higher risk may need to be seen sooner.
