“See your dentist every six months.”
You’ve heard it your whole life. It’s printed on toothpaste boxes, repeated by parents, and drilled into us from childhood. But is that rule actually backed by evidence, or is it just something everyone repeats without questioning?
It turns out this is one of the most debated questions in dentistry, and the research might surprise you. Large clinical trials have actually tested whether six months is the right number, or whether it’s simply a habit we’ve never stopped to challenge.
The real answer is more personal than a blanket rule. So, let’s look at what the research says and what actually determines your dental check-up frequency.
What Does the Research Actually Say?
This might surprise you. A major Cochrane review compared six-monthly check-ups with personalised, risk-based recall schedules. The result? There was little to no difference in outcomes between the two, based on high-certainty evidence.
The review tracked adults over four years. It measured tooth decay, gum disease, and quality of life. In each case, six-monthly visits performed no better than a schedule based on individual risk.
This doesn’t mean check-ups don’t matter. It means the six-month interval isn’t a magic number. Your ideal schedule depends on your own risk factors, not a universal rule.
So How Often Should You Go to the Dentist?
Most adults still benefit from a visit every 6 to 12 months. This is the range recommended by dentists here in Australia, and it lines up with the review’s findings. Because everyone’s risk is different, your dentist may suggest a different interval based on your history and current oral health.
For example, some people need more frequent visits. Others can safely stretch things out a little further. Here’s what tends to shift your ideal dental check-up frequency:
- Your history of tooth decay or gum disease. A history of problems generally means shorter intervals.
- How well you manage plaque at home. Great brushing and flossing habits can support a longer gap between visits.
- Whether you smoke. Smoking raises your risk of gum disease, so more frequent monitoring often helps.
- Certain medical conditions. Diabetes, for example, can affect gum health and oral healing.
- Whether you’re pregnant. Hormonal changes during pregnancy can affect your gums, so extra check-ins are often worthwhile.
- Orthodontic treatment or dental work. Braces, aligners, and recent restorations often need closer monitoring.
How Often for Teeth Cleaning?
A check-up and a clean usually happen together, but they’re not identical. Your check-up looks at your overall oral health. Your clean removes plaque and tartar that brushing can’t reach.
Most people need a professional clean every 6 to 12 months, similar to check-up timing. However, if you have gum disease or a heavier build-up of tartar, your dentist might recommend more frequent cleans to keep things under control.

How Often Should Children See the Dentist?
Children generally follow a similar schedule to adults, though the evidence here is less settled. The same Cochrane review found the data for children and adolescents was too uncertain to draw firm conclusions.
In practice, most dentists recommend a check-up every six months for kids. Because young teeth are still developing, this helps catch decay early and builds good habits from the start.
What Actually Happens at a Dental Check-Up?
A standard check-up covers more ground than most people expect. Your dentist reviews your medical history and examines your teeth, gums, and soft tissues. They also check for early signs of decay, gum disease, and even oral cancer.
X-rays aren’t taken at every visit. Instead, most dentists recommend bitewing X-rays every 18 to 24 months, since this timing balances useful diagnostic information with minimising unnecessary exposure. A typical check-up takes about 45 minutes, though your first visit may take longer while your dentist builds a full picture of your oral health.
When Should You Book Sooner?
Regardless of your usual schedule, some situations call for an earlier visit. Book promptly if you notice a toothache, facial swelling, or a broken tooth. The same goes for bleeding gums, a mouth ulcer lasting more than two weeks, or any trauma to your mouth. These signs shouldn’t wait for your next scheduled check-up.
Finding the Right Schedule for You
There’s no single answer to how often you should see the dentist, because your risk profile is unique to you. A schedule built around your own oral health, rather than a one-size-fits-all rule, gives you the best long-term outcome.

Frequently Asked Questions
Is it bad to skip a dental check-up for a year?
It depends on your individual risk. For some people, a longer gap makes little difference. For others, especially those with a history of decay or gum disease, a year without a check-up could let a problem develop unnoticed.
Your dentist can help you decide what’s safe for you.
Do I still need check-ups if my teeth feel fine?
Yes. Many dental problems, like early decay or gum disease, don’t cause noticeable symptoms until they’ve progressed. Regular check-ups catch these issues while they’re still small and easy to treat.
Does health insurance cover regular check-ups?
Many private health funds cover all or part of a routine check-up and clean under general dental extras. Bellevue Hill Dental is a preferred provider for several major health funds, so it’s worth checking your policy or asking our team before your visit.
How do I know if I need more frequent check-ups?
Your dentist will assess this at your visit, based on factors like your oral hygiene, medical history, and any current dental issues. If you’re unsure, it’s worth asking directly at your next appointment so your schedule reflects your actual risk level.
