Key points
- Adults: every 3 months to 2 years, depending on your oral health
- Children and teenagers: at least once a year
- People at higher risk of decay or gum disease need shorter gaps
- Early problems found at a check-up are quicker and cheaper to fix
Why the right gap differs
Someone with healthy teeth and gums and no new decay for years may only need a check-up every year or two. Someone with active gum disease, frequent new decay or a lot of fillings and crowns needs to be seen more often. The NHS also suggests more frequent checks in pregnancy and for people with type 2 diabetes, because of the higher risk of gum problems.
What happens at a check-up
A routine check-up usually covers:
- Questions about your general health and any problems since your last visit
- An examination of your teeth, gums and mouth
- X-rays if needed, to spot decay between the teeth or problems under the gum
- Advice on cleaning, diet and habits, and the date of your next check-up
Children
Children should first see a dentist when their first teeth appear, or by their first birthday, then at least once a year. Fluoride varnish and fissure sealants protect children's teeth from decay. See our children's dentistry guide.
When to see a dentist
See a dentist if you have
- Toothache, swelling or bleeding gums, whenever they happen, not just at your next check-up
- If you haven't had a check-up in 2 years (1 year for under-18s)

Common questions
Do I really need a check-up every 6 months?
Not necessarily. NICE recommends 3 months to 2 years for adults, depending on your risk. Your dentist will tell you what suits you.
How often should children see a dentist?
At least once a year, starting when the first teeth come through or by the first birthday.
What if nothing hurts?
Early decay and gum disease are often painless. That is exactly what a check-up is for.
Is a scale and polish part of a check-up?
Often it can be done at the same visit if you need one. Ask when you book.
