How often should you visit the dentist?

The short answer most people have heard is every six months. The more accurate answer is that six months is a sensible default, not a clinical rule — and the right interval for you depends on your actual risk.

Where "every six months" comes from

The six-month interval is convention rather than a figure derived from evidence. It suits a great many people well, which is why it persists: long enough for problems to be worth checking for, short enough that most are still small and cheap to fix when found.

But a 45-year-old with no fillings, healthy gums and a low-sugar diet, and a smoker with treated periodontitis and a dry mouth, do not have the same risk. Treating them identically means over-servicing one and under-servicing the other.

Reviews of the evidence have repeatedly found little support for applying a fixed six-month interval to everybody, and have recommended that intervals be set according to individual risk. That is the position this page takes, and it cuts both ways: for some people the honest answer is "less often than you have been coming", and for others it is "more often".

What actually determines your interval

Your dentist should set your recall interval based on:

Decay history — recent new cavities are the strongest predictor of future ones
Gum health — treated periodontitis usually needs three- or four-monthly maintenance, sometimes indefinitely, because the disease recurs when maintenance lapses
Plaque control at home, and how much calculus builds up between visits
Dry mouth, whether from medication or a medical condition — saliva is your main natural defence, and losing it raises decay risk substantially
Diet, particularly how often sugar and acid are consumed rather than how much
Smoking, which raises risk for gum disease and oral cancer
Existing dental work — crowns, bridges, implants and large fillings all need monitoring
Grinding or clenching, and any orthodontic appliances

In practice this means intervals ranging from three months to twelve or more. If you have been going every six months for years with no problems found, it is entirely reasonable to ask whether you could safely stretch it. Likewise, if problems keep appearing between visits, the interval is too long.

Ask us why your interval is what it is. You should get a specific answer about your mouth, not a policy.

Roughly where people land

Interval	Typically suits
3 months	Treated periodontitis in the maintenance phase; very high decay risk; significant dry mouth
4–6 months	Most adults; anyone with active disease being monitored; children
6 months	The common default — reasonable for average risk
9–12 months	Low risk: no recent decay, healthy gums, good plaque control, non-smoker
Longer than 12 months	Uncommon, and a judgement your practitioner makes rather than a preference

This is a guide, not a prescription. The interval is also not fixed for life — it should move when your circumstances do.

When your interval should change

Starting a medication that dries your mouth — several hundred common ones do
A new diabetes diagnosis, or control becoming harder
Pregnancy, which exaggerates the gum response to plaque
Starting orthodontic treatment, which makes cleaning harder
Cancer treatment, and before starting bisphosphonates or denosumab
After periodontal treatment, when maintenance intervals are shorter
A change in circumstances — a stressful period, a new job, anything that has disrupted the routine

Tell us when any of these happen rather than waiting to be asked.

What happens at a check-up

An examination covers the teeth, gums, tongue, cheeks, palate, lips and jaw joints — not just teeth. Radiographs are taken when clinically indicated, at intervals based on your risk, because decay between teeth and bone loss are not visible to the eye.

It also includes a look for anything abnormal in the soft tissues. Oral cancer is uncommon but far more survivable when found early, and it is usually painless at the stage when it is most treatable. This is one of the better arguments for keeping up regular visits even when nothing hurts.

A check-up is often paired with a professional clean, which removes calculus — hardened plaque that brushing cannot shift.

How X-ray intervals are decided

A common source of confusion, so worth spelling out. Radiographs are not on the same schedule as the examination.

Bitewings — typically every one to two years for an adult at ordinary risk; more often where decay is active, less often where it is not
An OPG — taken when there is a specific question, such as wisdom teeth or implant planning, rather than routinely
Periapical films — taken for a specific tooth with a specific problem

You are entitled to ask what a film is for, and to decline it. Declining means working with less information, and we will say what that changes. If you are pregnant, tell us — routine films are deferred.

The point everyone misses

Dental problems do not hurt until late. Decay is painless until it reaches the nerve. Gum disease is usually painless until teeth loosen. By the time something hurts, the cheap option has often passed.

That is the actual argument for regular check-ups: not that they prevent problems, but that they catch them while a filling is still a filling rather than a root canal or an extraction.

It is also why comparing this visit with the last one matters more than either on its own. A shadow between two teeth that is unchanged over two years behaves very differently from one that has visibly advanced — the first is usually monitored, the second restored. That comparison only exists if you keep turning up.

What it costs, and how cover works

Most extras policies cover two preventive visits a year, and the benefit is set against item numbers rather than against the practice's fee — which is why the gap differs between practices. HICAPS claiming means you pay only the gap on the day.

Three practical notes:

Annual limits do not roll over. If yours resets on 30 June or 31 December, an unused balance is simply lost
A policy that covers two visits a year is a commercial decision, not a clinical one. If your clinical interval is three-monthly, the fund is not paying for all four; if it is twelve-monthly, there is no obligation to use both
Cost should be said out loud. If the interval we recommend is not affordable, tell us and we will talk about what matters most rather than you simply not coming

For eligible concession card holders, public dental services in Victoria provide care through community dental agencies and the Royal Dental Hospital of Melbourne. Waiting lists apply for general care; emergency care is prioritised.

Do not wait for your next check-up if

Book sooner if you have:

Pain, particularly pain that wakes you at night or lingers after hot or cold
Gums that bleed regularly when you brush
A chipped, cracked or broken tooth, or a lost filling or crown
A loose adult tooth
Persistent bad breath or a bad taste that does not resolve
An ulcer, lump, or red or white patch lasting more than two weeks — have this looked at
A bite that suddenly feels different

And go to a hospital emergency department, not a dentist, for facial swelling that is spreading, difficulty breathing or swallowing, or fever with dental pain. See our dental emergency page.

If it has been years rather than months

This is common, and it is not a reason to keep putting it off — the gap tends to grow precisely because people are embarrassed about its length.

There is no lecture. Book a check-up and clean, say when you ring that it has been a long time, and the first appointment can be as unhurried as you need. See dental anxiety if the reason for the gap is nerves rather than time.

What usually happens at that first visit: a conversation, an examination, radiographs if indicated, and a written plan in order of priority. Not all of it at once, and not all of it immediately. Most people find the first visit considerably less bad than the anticipation.

Children

First visit by around twelve months of age, or when the first tooth appears — mostly to establish familiarity and check development. Children often need shorter intervals than adults because decay progresses faster in baby teeth. Eligible children aged 0–17 may be able to claim under the Child Dental Benefits Schedule.

Children's intervals move more than adults' do: a period of active decay, a new set of molars erupting, or braces going on can all shorten it, and it usually lengthens again once things are stable.

Changing practices, and second opinions

You are not tied to a practice, and your records are yours to request. If you move, or simply want a different practitioner, ask for your records and radiographs to be sent on — that is routine and nobody takes offence.

A second opinion is also a reasonable thing to seek, particularly before a large or irreversible treatment plan. Take your radiographs with you so the second practitioner is not starting from nothing.

How to tell whether you are being over-treated

A fair worry, and there are honest signals.

Reassuring: being shown the problem on a screen or a radiograph; being told the size and depth; "watch and review" appearing on the plan with a review date; a written quote with item numbers; being told what happens if you do nothing; no pressure to decide today.

Worth questioning: a long list of treatment produced at a first visit with no explanation of urgency; every tooth needing something; a same-day discount that expires; being unable to get a written plan; a practitioner who reacts badly to the words "second opinion".

Questions we are asked

Can I go longer than six months if nothing is wrong? Possibly, and it is a fair question to ask. It depends on your risk factors rather than on how long you have gone without a problem.

Does a check-up always mean X-rays? No. They are taken where they would change what happens next, at intervals matched to your risk.

Is a clean necessary every time? Usually it is paired with the examination, because calculus builds up in everyone. How much you form varies a great deal between people.

My teeth feel fine — why bother? Because decay and gum disease are both painless until late. Feeling fine is not evidence.

Will you just find something to charge me for? Findings are explained with the screen turned towards you, and "monitor it and do nothing" is a recommendation we make often. Anything further is quoted in writing before it starts.

I have dentures and no natural teeth. Do I still need to come? Yes, though less often for different reasons — the fit of the denture, the tissues underneath, and the soft-tissue check, which matters regardless of how many teeth you have.

How long is a check-up appointment? Usually a single appointment for examination and clean, longer if there is significant calculus or gum disease. We will tell you which before you book.

Can the family come together? Often, depending on availability. Ask when booking.

How often should I go to the dentist?

It depends on you, not on a universal rule. Six months is the familiar default and suits many people, but the honest answer is that the interval should be set after an examination, based on your risk. Some people are safely seen every twelve months; others need every three or four.

What makes someone need to go more often?

Active gum disease, a history of frequent decay, a dry mouth from medication, smoking, poorly controlled diabetes, extensive crowns, bridges or implants to maintain, orthodontic appliances, exposed root surfaces, heavy grinding, or a diet high in sugar or acid. Anyone in those groups usually benefits from three- or four-monthly visits, because problems develop faster and are cheaper to catch early.

Can some people safely go longer?

Yes. An adult with healthy gums, no recent decay, good daily cleaning and none of the risk factors above can reasonably be seen less often than every six months. Stretching the interval is a clinical decision made with you, not something to decide alone — and it is reviewed each time, because circumstances change.

Why go at all if nothing hurts?

Because the conditions worth catching are painless at the stage when they are easiest to treat. Decay does not hurt until it reaches the nerve. Gum disease is typically painless until teeth loosen. Oral cancer often begins as a painless patch or ulcer. Pain is a late signal, not an early one.

What happens at a check-up?

An examination of the teeth, gums, tongue, cheeks, palate and throat, a review of your medical history and medications, X-rays where clinically indicated to see between and inside teeth, and gum measurements where gum disease is suspected. Findings are explained and anything needing attention is set out in writing with costs before it is booked. A professional clean is usually done at the same visit.

Is a clean the same as gum treatment?

No. A routine scale and clean removes plaque and calculus and keeps healthy gums healthy. Treating established gum disease is a longer procedure, often over several appointments and under local anaesthetic where pockets are deep, with the gums re-measured afterwards. If you have periodontitis, a routine clean at six-monthly intervals is not enough.

When should I come in sooner?

Do not wait for the next routine visit if you have toothache, gums that bleed regularly, a broken or loose tooth, a lost filling or crown, a lump or an ulcer that has not healed in two weeks, or increasing sensitivity. Phone rather than booking online so it can be triaged.

When is it a hospital matter?

Difficulty breathing or swallowing, facial swelling that is spreading, fever with facial swelling, bleeding that will not stop, or a significant facial injury — go to a hospital emergency department or call 000 rather than waiting for a dental appointment.
