How Often Should You Go to the Dentist? What the Evidence Actually Says

Ask ten Australian dentists how often you should go to the dentist and most will tell you every six months. We've said it ourselves, plenty of times. But that six-month rule rests on a much thinner evidence base than nearly anyone realises, and after more than 30 years at Bradbury Dental Surgery treating families across Campbelltown, we've come to think the more useful question isn't how often. It's how often for you.

How Often Should You Go to the Dentist? The Short Answer

Most Australian adults should see a dentist every 6 to 12 months. That's the range healthdirect gives, and it's deliberately a range rather than a single number, because the right interval depends on your risk of dental disease rather than on the calendar.

Queensland Health puts an outer limit on it: even for people at very low risk, the gap between check-ups shouldn't stretch beyond two years. So there's a floor and a ceiling. Where you sit between them is the actual question, and it's one your dentist should be answering with you rather than for you.

Why "Every Six Months" Isn't an Australian Guideline

There is no Australian national guideline setting how often you need to visit a dentist. There's no World Health Organization guideline either.

What Australia does have is a national evidence-based recommendation, and it says something different to what most people assume: everyone has different oral health needs and risk levels, and the frequency of check-ups should reflect that. Talk to your dental practitioner about your risk. That's the recommendation. Not a number.

The six-month habit is old. Back in 1977, the dental researcher Aubrey Sheiham reviewed the evidence and concluded there was nothing supporting six-monthly checks for everyone. Nearly 50 years on, that's still roughly where the science sits.

We still get patients apologising for being "late" because it's been eight months since their last visit. For a lot of people, eight months is completely fine. What's happening inside the mouth matters far more than what the calendar says.

What the Research Says About Six-Monthly Check-Ups

For adults already under regular dental care, a large Cochrane review found little to no difference between risk-based recall and fixed six-month recall in tooth decay, gum bleeding, or oral health quality of life over four years. That's high-certainty evidence, which is about as strong as dental research gets.

The same review found little to no difference for lower-risk adults stretched out to 24-month intervals. For children and adolescents, the evidence is much less certain.

Now, that finding gets misread constantly, so let's be clear about what it doesn't say. The trials compared different intervals among people who were still attending and still being risk-assessed. Nobody compared going to the dentist against not going at all.

Stretching your interval on your dentist's advice is a reasonable, evidence-supported thing to do. Disappearing for six years is not the same thing.

And risk isn't fixed. It shifts with your health, your medications, your job, your stress levels. Someone who's been low-risk for a decade can move into a higher-risk group in a single year, which is exactly why the assessment gets repeated rather than done once.

Who Needs to Go More Often, and Who Can Stretch It Out?

Risk sets the interval, not age and not habit. Here's roughly how we think about it in practice:

Your situation	Typical interval
Active gum disease, or a history of periodontitis	3 to 4 months
Smoking or vaping	3 to 6 months
Type 1 or type 2 diabetes	3 to 6 months
Pregnancy, particularly with bleeding gums or reflux	3 to 6 months
Dry mouth from medication	3 to 6 months
Braces, aligners, implants, or multiple crowns	3 to 6 months
New decay or repeat fillings in the past two years	6 months
Stable mouth, no decay or gum problems for years, good home care	9 to 12 months

Dry mouth is the one people underestimate most. We see it constantly in patients over 50, especially those on blood pressure medication, and it changes the risk picture quickly because saliva is doing a lot of quiet protective work that nobody notices until it stops. Antidepressants, antihistamines and diuretics do the same thing.

Gum disease is the other one. Early gingivitis rarely hurts, which is why patients are often surprised when we pick it up, and tartar under the gumline can't be shifted by brushing at all no matter how thorough you are. If you've already been treated for it, closer review through our gum disease treatment is usually the sensible call. We cover the home side of this in our guide to removing plaque and tartar.

How Often Should Children Go to the Dentist?

Children generally follow a similar 6 to 12 month pattern, with the first visit much earlier than most parents expect. We tell parents to aim for the first birthday, and Australia's National Oral Health Plan recommends no later than age two.

There's a practical reason to keep kids on schedule here in the Macarthur region. The Child Dental Benefits Schedule covers up to $1,158 of basic dental care per eligible child aged 0 to 17 across two consecutive calendar years, and that figure applies to periods starting in 2026. Anything unused at the end of the two years disappears. It doesn't roll over. So families who book once and then leave it often forfeit money they were entitled to.

You can check eligibility through myGov, and we've set out how it works on our CDBS page. Our children's dentistry appointments are commonly bulk billed under the scheme.

Worth knowing: in 2023 to 2024 there were close to 88,600 hospitalisations across Australia for dental conditions that earlier treatment could have prevented. The highest rate was in children aged 5 to 9.

What Happens If You Leave It Too Long?

The clearest signal in the Australian data isn't how many months you leave between visits. It's whether you come for a check-up or only turn up when something hurts.

Among Australian adults who usually visit for a problem, 35% reported toothache in the previous year. Among those who usually visit for a check-up, it was 11%. Same country, same dentists, very different experience of having teeth.

That gap exists because decay and gum disease are quiet at the start. By the time a tooth really hurts, the cheap and simple options have often passed. A small filling becomes a crown, or worse. If you want to know what to watch for at home, we've written about the early signs of tooth decay.

We'll be honest about the other barrier, because it's real. Around 1 in 5 Australian adults report that cost stopped them getting dental treatment their dentist recommended. If that's the situation you're in, say so at the appointment rather than cancelling it. We can usually sequence treatment across visits, and there are payment plan options including Afterpay, Zip and the National Dental Plan.

Frequently Asked Questions

Is going to the dentist every six months really necessary? 

For many people, yes, but it isn't a universal rule and there's no Australian guideline requiring it. Six months is a sensible default that suits a large share of patients. Your dentist should set your interval based on your risk of decay and gum disease.

Can I go to the dentist just once a year? 

Yes, if your mouth is stable and your dentist agrees it's appropriate. healthdirect's recommended range runs from 6 to 12 months, so annual visits sit comfortably inside it for lower-risk adults. Twelve months is too long if you smoke, have diabetes, or have a history of gum disease.

What happens if I haven't been to the dentist in years? 

You book an appointment and we start from where you are. A first visit after a long gap usually involves a full examination and x-rays to see what's happening below the surface, then a plan you can work through in stages. Nobody at Bradbury Dental Surgery is going to lecture you about the gap.

Do I still need check-ups if I wear dentures or have no natural teeth? 

Yes. Examinations check far more than teeth, including your gums, jaw joints, lymph nodes and soft tissues, and screening for oral cancer matters just as much without natural teeth. Dentures also need review as the jaw changes shape over time.

If you're still not sure how often you should go to the dentist, that's exactly what a check-up is for. We'll look at your risk, tell you what we find, and give you a recall period that fits your mouth rather than a number pulled off the calendar.
