Twice a year is a reasonable starting point, but it is not the right gap for everyone. Someone with healthy gums and no new decay for years may only need a check-up every year or two, while someone with active gum disease may need to be seen every few months. The aim is to match visits to how quickly problems are likely to develop in your mouth.
Australian Dental Association patient information puts it this way: most dentists recommend a check-up every 6 to 12 months, adults at very low risk of oral disease may only need to visit every one to two years, and people at high risk of gum disease or decay may need to come every three months.
The six-month habit and what research says about it
Six-monthly visits became a widespread habit long before there were trials testing them. When researchers did compare intervals, the differences were smaller than many expect. A 2020 Cochrane review (Fee and colleagues) included a large UK trial of adults who already saw a dentist regularly. Over four years, there was little to no difference in decay, gum bleeding or quality of life between six-monthly check-ups and check-ups timed to each person's risk.
That does not mean visits do not matter. It means that, for people already looked after regularly, the gap can be tailored without losing benefit. The UK's NICE guideline recommends setting it for each person after a risk assessment, between 3 and 24 months for adults and 3 and 12 months for children and teenagers.
Signs you probably need to come more often
Your dentist or OHT looks at your history and current mouth when suggesting a recall. A shorter gap is more likely if you have had new decay recently, if you have gum disease or have been treated for it, or if plaque and tartar build up quickly. The ADA lists smoking, diabetes and some medicines among the factors your dentist will consider. A dry mouth, frequent snacking or sugary drinks, crowns, implants or braces that need monitoring, and difficulty cleaning because of health problems can all point the same way.
A longer gap may suit you if your gums are healthy, you have had no new decay for several years, and you clean well every day. That decision is best made with your dentist, and it can be shortened again if things change.
A rough guide
| Risk | Usual gap between check-ups | Often fits |
|---|---|---|
| Very low | One to two years | Healthy gums, no recent decay, consistent home care |
| Average | 6 to 12 months | Many adults |
| High | About every 3 months | Active gum disease, frequent decay, other risk factors |
These bands follow the ADA's patient guidance and are not a diagnosis. Your dentist will suggest a gap and adjust it over time.
Children have their own timetable
The ADA advises that children at low risk should see a dentist at least once a year, and children at higher risk of decay may need visits every three to six months until their risk settles. Decay can move quickly in baby teeth, so regular visits help catch it early and give children a chance to get used to the dental chair. Our guide to a child's first dental visit explains when to start. Eligible children may be bulk billed under the Child Dental Benefits Schedule, which covers children aged 0 to 17 in eligible families.
What a check-up is for
Most dental problems develop quietly. Early decay and gum disease often cause no pain until they are advanced, when treatment is usually bigger and more expensive. At a check-up your teeth, gums and the soft tissues of the mouth are examined, and hardened tartar that brushing cannot shift can be removed with a scale and clean. X-rays are taken only when they are likely to add useful information, which our article on how often you need check-ups and X-rays explains.
Common questions
Can I go longer than a year between visits?
Some adults at very low risk can, according to the ADA, but it is a decision to make with your dentist rather than a way to put off care. Our article asking if you really need a check-up every six months looks at this in more detail.
It has been years since my last visit. Where do I start?
That is common and not a reason to stay away. A check-up shows where things stand and gives you a plan, and the sooner it happens, the more likely any problems are still small. You will usually receive a written treatment plan, often by email, if anything needs attention.
My teeth feel fine. Do I still need to go?
Yes. Feeling fine does not rule out early decay or gum disease, which are usually painless at first. Finding them early is what regular check-ups are for.
Find the interval that suits you
If you are not sure how often you should be coming in, a check-up is the simplest way to find out. Our dentists and OHTs see adults, children and families at our Melrose Park practice, and health funds can be claimed on the spot. You can book a check-up or see the current examination and clean options on our offers page.
