How Often Should You Get Your Teeth Cleaned?
There is no single right answer. Most people are told every six months, but the best interval depends on your mouth. Some people do well once a year. Others need a cleaning every three or four months. Your gums, your risk, and your history decide, not the calendar.
I hear the same worry all the time at The Village Dentist on Annette Street. "I always come every six months. Why would I need to come more often?" It is a fair question, and the honest answer is that six months is a habit, not a law of nature.
Where did the six-month rule even come from?
Here is the part that surprised me early in my career. The six-month cleaning is convention, not hard science. It became the default through routine and old advertising, not because research proved everyone needs exactly that schedule.
For some people, twice a year is close to right. For others it is too often. For many, it is not often enough. Seven out of 10 Canadians will develop gum disease at some point, according to the Canadian Dental Association. The gap between your cleanings is one of the biggest levers you actually control.
Most people think everyone needs the same schedule. Here is what happens in a real mouth. Plaque, a soft film of bacteria, builds up near the gumline every day. If daily brushing and flossing miss it, it hardens into tartar, also called calculus. Tartar is rough, and you cannot remove it at home. Only a dental instrument can. The faster you build tartar, the sooner you need us.
What actually decides your interval?
Wait, is there a right number for you? Yes, and it comes down to your risk. Your teeth and gums tell us how fast trouble builds. Some people make tartar quickly. Others barely make any.
Talk to us about a shorter interval if any of these apply to you:
- A history of gum disease. Past bone loss and deeper pockets mean you need closer monitoring. If your gums bleed when you floss, that is inflammation worth checking, and our post on bleeding gums and gum disease explains why.
- Smoking or vaping. Smoking cuts blood flow to the gums and can hide bleeding, so warning signs get missed.
- Diabetes. Higher blood sugar makes it harder for your body to fight gum infection.
- Dry mouth. Many medications reduce saliva, and less saliva means more plaque and more decay.
- Braces or clear aligners. Brackets, wires, and attachments trap plaque, so cleanings usually need to be closer together.
- A tendency to build tartar fast. Some mouths just do, no matter how well you brush.
Gum health in Canada is drifting the wrong way, which is why this matters. Statistics Canada found that 83% of adults aged 20 to 79 had bleeding when their gums were probed, and more than one-third now have deeper gum pockets, up from about one in five in 2007 to 2009.
What does the evidence say about six-month cleanings?
Here is where it gets interesting. A large research review looked at whether fixed six-month checkups beat other schedules. The answer surprised a lot of people. There were no dental health benefits to six-monthly checkups compared with risk-based intervals or two-yearly checkups for low-risk people, and there was no difference in bleeding gums.
So the calendar does not decide. Your risk does. National guidance agrees. NICE recommends recall intervals between 3 and 24 months, set for each patient based on their risk, with adults assigned an interval of 3, 6, 9, or 12 months, or longer if their gums stay stable. The shortest interval for anyone is 3 months. That is where the 3, 4, 6, 9 month idea comes from. It is individual, not one size for all.
What actually happens at a hygiene visit?
Did you know a cleaning is more than a polish? A hygiene visit has a few parts, and each one tells us something.
First, we look and measure. We check your gums for redness, puffiness, and bleeding, and we measure the little pockets around each tooth with a small probe. Healthy pockets are shallow. Deeper ones point to gum disease.
Next comes the scaling. We remove the tartar above and, where needed, just below the gumline, since your toothbrush cannot reach it. Then we polish to lift surface stain and smooth the teeth. We finish with a look for decay and, when it is due, X-rays and an exam.
Have no fear if it has been a while. I have seen every kind of mouth in about 25 years on Annette Street in Bloor West Village, and no one gets a lecture. We meet you where you are and build a plan from there.
Does my insurance decide how often I come?
No, and this trips people up. Your coverage and your clinical need are two different things. Insurance plans cap how often they will pay, but that cap is a billing rule, not a health recommendation.
The Canadian Dental Association is clear on this. It says the schedule should be determined based on a risk assessment and what meets your individual needs, decided together with your dentist. If your mouth needs a cleaning every three or four months, we plan around your health first, then sort out the coverage.
The Canadian Dental Care Plan works this way too. It covers cleanings and exams up to a set limit, and care beyond that limit can be requested. If you want the coverage details, our guides on what CDCP actually covers and whether CDCP covers cleanings and exams walk through it.
How do we find your number?
Simple. We start somewhere sensible, then watch your gums. If you have no bleeding and no tartar buildup between visits, your interval is working, and we may stretch it. If we see bleeding, inflammation, or calculus creeping back, we tighten the schedule. Your mouth tells us what it needs.
Home care sets the pace between visits. Brushing along the gumline and daily flossing do most of the work, and a good brush helps. Our guide to choosing and using a toothbrush covers the basics. Better home care can earn you a longer interval.
Frequently Asked Questions
Q: How often should I get my teeth cleaned?
There is no single answer that fits everyone. The best interval depends on your gum health, your risk factors, and how fast you build tartar. For some people once a year is enough, while others do better every three or four months. Your dentist sets it with you based on what your mouth needs.
Q: Is six months the right interval for everyone?
No. Six months is a convention, not a rule proven for everyone. Research found no dental health benefit to fixed six-month checkups over risk-based or longer intervals for people at low risk. Some people need to come more often, and some can safely wait longer.
Q: What makes someone need cleanings more often?
A history of gum disease, smoking or vaping, diabetes, dry mouth, and orthodontic appliances like braces or aligners all raise your risk. Bleeding gums and fast tartar buildup are signs too. Any of these can push your ideal interval to three or four months.
Q: Can I go longer than six months between cleanings?
Sometimes, yes. If your gums stay healthy, you have no bleeding, and little tartar builds up between visits, a longer gap can be safe. National guidance allows intervals up to two years for low-risk adults. Your dentist confirms whether that fits you.
Q: Why do I need a professional cleaning if I brush and floss well?
Because brushing and flossing cannot remove tartar once it hardens. Only a dental instrument can. Even careful brushers miss spots where plaque hardens into calculus, and that is what a hygiene visit clears away.
Q: Does my insurance limit how often I can get a cleaning?
Insurance plans cap how often they will pay, but that limit is a billing rule, not a clinical recommendation. Your dentist decides the healthy interval based on your risk. If your coverage limit and your clinical need differ, we plan around your health first and then work through the coverage.
Q: How do I know if my current cleaning schedule is working?
If you have no bleeding and no tartar buildup between visits, your interval is working well. If you notice bleeding, puffy gums, or buildup you can feel with your tongue, it is time to come in sooner. We adjust your schedule based on how your gums respond over time.
