Most people should go every 6 to 12 months, and that is the standard advice from healthdirect. But the honest answer is that it depends on your own risk of dental problems, not a fixed rule for everyone. Someone with healthy teeth and gums may only need a visit once a year, while a person prone to gum disease or decay may need one every three months. The best approach is to let your dentist set an interval based on your mouth, then stick to it.
Where the six-month rule comes from
Almost everyone has heard "go every six months," and for a lot of people it is a sensible default. Regular visits let a dentist catch decay and gum problems while they are small and cheap to fix, and the clean removes the hardened tartar that brushing cannot.
Here is the part most pages leave out, though. The six-month rule is a rough convention, not a hard scientific law. A 2020 Cochrane review, one of the most rigorous types of evidence, found that six-monthly check-ups did not prevent more decay or gum bleeding than check-ups scheduled around a person's actual risk. A separate review found that for many people, routine scale and cleans made little difference to gum inflammation compared with less frequent cleaning. That does not mean skip the dentist. It means the right gap between visits is personal, and for plenty of people it is not automatically six months.
It should be based on your risk
The modern, evidence-based approach is called risk-based recall. Your dentist looks at how likely you are to develop problems, then sets your interval to match. Here is roughly how that plays out.
Your risk of dental problems | Typical interval |
Higher risk (gum disease, smoker, diabetes, frequent decay) | Every 3 to 6 months |
Average risk | Every 6 to 12 months |
Lower risk (healthy, stable, excellent hygiene) | Every 12 to 24 months |
This is why two people can get different advice and both be right. The number is tailored, so it is worth asking your dentist directly, "how often do I actually need to come back?" rather than assuming it is six months for everyone.
Who should go more often
Some people genuinely benefit from visits every three to four months, because their risk of things going wrong is higher. You are likely in this group if you:
have gum disease or a history of it
smoke or vape, which raises gum disease and oral cancer risk
have diabetes, which is linked to gum problems both ways
get cavities often, or have had a lot of fillings
have a dry mouth from medications or a health condition, since saliva protects teeth
are pregnant, when hormonal changes make gums more prone to inflammation
wear braces, which trap plaque and are harder to clean around
For these situations, more frequent check-ups and cleans are about staying ahead of a real risk, not overservicing.
Who can often go less often
If your oral health is stable and your risk is low, you may safely stretch to once a year, or in some cases every 18 to 24 months. That usually describes someone with no recent decay, healthy gums, excellent brushing and flossing, no smoking, and no medical conditions affecting the mouth. Even then, an occasional professional check still matters, because some problems are painless early on and easy to miss yourself. A longer interval is a reward for low risk, not a reason to stop going altogether. A fluoride treatment at those visits can add extra protection between them.
How often for children
Children generally follow the same six to twelve month pattern, starting from around their first birthday or when the first tooth appears. Young teeth can develop decay quickly, so regular visits help catch it early and build a comfortable habit with the dentist. Kids at higher risk may be seen more often, and preventive steps like fissure sealants can reduce decay in the deep grooves of back teeth. Many Australian children are also eligible for subsidised dental care through the Child Dental Benefits Schedule.
Frequently asked questions
How often should you get a dental check-up and clean? Most people should go every 6 to 12 months, but the ideal interval is based on your risk. Higher-risk people may need every 3 months, while those with healthy, stable teeth can sometimes go 12 to 24 months. Ask your dentist to set an interval for you.
Do I really need to go every six months? Not necessarily. Six months is a common default, but research shows risk-based intervals work just as well for many people. Some need to come more often, others less. Your dentist can tell you which applies to you.
How often should children see the dentist? Usually every 6 to 12 months, starting from about age one or the first tooth. Children at higher risk of decay may need more frequent visits, and preventive care like sealants and fluoride helps protect young teeth.
