A dental check-up is an exam by your dentist plus, usually, a cleaning. The exam covers your health history, your gums, every tooth, your jaw and neck, and a look for anything that shouldn't be there, with X-rays only when you're due for them.
The Canadian Dental Association lists a typical visit the same way: your dentist examines your teeth, gums and entire mouth, cleans off the plaque and tartar that brushing can't reach, offers advice, and talks with you about how often to come back (Canadian Dental Association). In about 25 years of practice in Bloor West Village, I've noticed many people have never had anyone explain what each step is for. So here's the visit in the order it happens.
You might think the dentist pops in at the end to check the hygienist's work. Not so. The CDA says the exam is something only your dentist can perform, and that the dentist is looking for things that can affect both your oral health and your overall health (CDA, The Dental Exam).
What happens before anyone looks in your mouth?
Questions come first. The CDA says the exam includes a complete medical history, so your dentist knows about health conditions that could affect treatment or be linked to problems in your mouth (CDA, The Dental Exam).
At a first visit, the Ontario Dental Association says your dentist will ask about any medications you take, whether you smoke or drink alcohol often, whether you're pregnant, and your family history (Ontario Dental Association). Smoking and frequent drinking come up because of oral cancer risk.
Why does your medication list matter to a dentist? The side effects show up in your mouth. The CDA notes that side effects of some medications can often include dry mouth and overgrown gums (CDA, The Dental Exam). The ODA names antihistamines and antidepressants as drugs that may cause dry mouth, and says blood thinners can cause minor bleeding during something as simple as a cleaning (ODA, Prescription Drugs).
Tell us about everything, including the allergy pill you take in spring and the puffer you use twice a year. The ODA's advice is to update your health and medication status every time you see your dentist (ODA, Prescription Drugs). Our post on Ozempic, dry mouth and your teeth explains why a dry mouth changes your cavity risk.
Why does the hygienist call out numbers while poking your gums?
Those numbers are pocket depths. Your hygienist or dentist slides a small measuring tool between each tooth and the gum to see how deep the space is (ODA, Gum Disease). Have no fear. It's a ruler, not a needle.
Here's how to read the numbers. Statistics Canada explains that probing depths of up to 3 mm are generally considered healthy, while deeper pockets may indicate early signs of gum disease (Statistics Canada).
Bleeding when the gums are measured counts too. StatCan says that bleeding reflects active inflammation, and in its national survey 83% of Canadians aged 20 to 79 showed gum bleeding in at least one tooth during probing (Statistics Canada). The same survey found just over one-third of adults had deeper pockets (4 mm and over) in 2022 to 2024, compared with one in five adults in 2007 to 2009.
Why measure if nothing hurts? Because gum disease is painless until the final stages, so it often goes unnoticed (ODA, Gum Disease). The CDA calls it one of the main reasons adults lose their teeth, and says it can even be reversed in its early stages (CDA, Gum Diseases).
Catching it early is the whole point of the numbers. Our post on bleeding gums and gum disease covers what happens when they start to creep up.
What is the dentist looking for, tooth by tooth?
The CDA's list is a good map of what goes through my head during the exam (CDA, The Dental Exam):
- Damaged, missing or decayed teeth, including early signs of cavities.
- How older work like fillings, crowns and root canals is holding up.
- The position of your teeth, such as spacing and how your bite fits together.
- Signs that you clench or grind, which can cause headaches or a sore jaw.
The exam goes past the teeth, too. The CDA says your dentist checks the health and function of your jaw joint, and feels the glands and lymph nodes in your neck for signs of inflammation that could point to general health problems (CDA, The Dental Exam).
What gives, if nothing hurts? The ODA says many dental diseases don't show symptoms or cause pain early on, and by the time you have pain or swelling, the disease has already progressed (ODA, General Dental Examination).
Is the oral cancer check part of a normal visit?
Yes. The ODA says an oral cancer exam done by your dentist during a routine dental exam is fast, easy and painless (ODA, Oral Cancer). In other words, it happens during the check-up itself, not at a separate appointment.
Your dentist feels for lumps or irregular tissue in your neck, head, face and inside your mouth, and looks for sores or discoloured tissue (ODA, Common Dental Procedures).
The University of Toronto's Faculty of Dentistry, where I trained, describes the inside-the-mouth part step by step. The tip of your tongue is held with a piece of gauze and moved from one side to the other (U of T Faculty of Dentistry). The sides of the tongue and the floor of the mouth get particular attention, because cancers develop in those areas more frequently than on the top of the tongue or the roof of the mouth. The faculty describes the exam as not painful, but a slightly odd feeling.
Do you need the check if you don't smoke? Yes. The Public Health Agency of Canada says about 25% of oral cancers occur in people who don't smoke or drink alcohol (Government of Canada, Oral cancer). People over 45 are at higher risk, and people over 60 have the highest incidence (Government of Canada, Oral cancer).
Between visits, watch for a sore or patch in your mouth or on your lip that doesn't heal within 2 weeks, and get it looked at (Government of Canada, Oral cancer). If it's been years since your last exam, our post on coming back to the dentist after a long gap covers what the first visit back looks like.
Do you need X-rays every time?
No. The CDA says how often you need X-rays depends on your oral health, and a healthy adult who hasn't had cavities or other problems for a couple of years probably won't need them at every appointment (CDA, Dental Care FAQs).
In Ontario, the order matters. The Royal College of Dental Surgeons of Ontario says a dentist must review your health history and complete a clinical exam before prescribing X-rays (RCDSO). It also says the timing of bitewings (the X-rays that show cavities between back teeth) should be based on your cavity risk, never on a fixed time period alone, such as every six months.
Health Canada's safety code for dental X-ray equipment says the same thing from the other side: X-rays should only be taken after a clinical exam has found an expected health benefit to you (Health Canada, Safety Code 30).
When you are due, X-rays show what my eyes can't. The CDA lists cavities under existing fillings, fractures, impacted wisdom teeth, decay under the gum line, and bone loss from gum disease (CDA, The Dental Exam). The CDA also notes dental X-rays deliver little radiation (CDA, Dental Care FAQs). Our post on radiation from dental X-rays puts the dose in plain numbers.
What does each part of the visit cost?
A check-up isn't one fee. It's a few line items added together, and our post on OHIP and dental insurance covers who pays for what.
Here are the 2026 Ontario Dental Association fee-guide figures, as publicly reported and laid out in our post on the real cost of dental care in Toronto:
- Recall exam (the regular check-up exam): $96 to $182.
- Complete exam (a new-patient exam): $96 for baby teeth, $143 for mixed, $191 for adult teeth.
- Scaling (the cleaning): $65 to $70 per unit of time.
The ODA says dentists aren't required to follow the fee guide, so fees can vary above and below it (ODA, Dental Costs Explained). The guide has more than 1,400 codes, and you won't find words like "check-up" or "cleaning" in it.
If the exam turns up something that needs treatment, the ODA says estimates are rarely given without an exam, and your dentist should give you a cost estimate before going ahead (ODA, Dental Treatment Estimates). Our post on whether your dentist is upselling you lists the questions to ask at that point.
Why isn't it "every six months" for everyone?
Six months is a habit, not a rule. The CDA says how often you go depends on your oral health needs, and for many people that means an exam every six months, with some people coming more or less often (CDA, Dental Care FAQs). The ODA recommends seeing your dentist at least once a year, more often depending on your needs, your general health and habits like smoking (ODA, General Dental Examination).
The research backs a personal approach. A Cochrane review found that for adults attending dental check-ups, there was little to no difference between risk-based and 6-month recall intervals in cavities, bleeding gums and quality of life over 4 years (Cochrane review, PubMed).
So your interval is worth talking through after the exam. Our post on 3, 4, 6 or 9 months between cleanings goes through how an interval gets set.
Some days the schedule pushes me, and even then I'd rather run five minutes behind than rush the part where we set your next visit.
What happens at the end of the visit?
The cleaning has two parts. The CDA describes scaling as removing the tartar and plaque that can lead to gum disease, and polishing as smoothing your teeth so plaque has a harder time building up again (CDA, Check-Up).
Fluoride is an option, not an automatic add-on. The ODA says a fluoride treatment may be applied to strengthen your teeth (ODA, Common Dental Procedures).
Then comes the part I care most about. The CDA says your dentist may give you a summary of the findings, and if not, be sure to ask, because you're a full partner in your oral health care (CDA, The Dental Exam).
Try this: before you leave, ask what your gum numbers were and whether anything changed since last time.
Frequently Asked Questions
Q: What do the gum numbers at a check-up mean? They're the depth, in millimetres, of the space between each tooth and the gum. Statistics Canada says probing depths of up to 3 mm are generally considered healthy, while deeper pockets may indicate early signs of gum disease (Statistics Canada). Bleeding while the gums are measured is a sign of active inflammation.
Q: Do I need X-rays at every dental check-up? No. The CDA says a healthy adult with no cavities or other problems for a couple of years probably won't need X-rays at every appointment (CDA, Dental Care FAQs). In Ontario, the RCDSO says X-rays are prescribed after a clinical exam, based on your risk, not on a fixed time period alone (RCDSO).
Q: Does a dental check-up include an oral cancer screening? Yes. The ODA says an oral cancer exam during a routine dental exam is fast, easy and painless (ODA, Oral Cancer). Your dentist feels your neck, head, face and mouth for lumps and looks for sores or discoloured tissue (ODA, Common Dental Procedures).
Q: Who does the exam, the hygienist or the dentist? The dentist. The CDA says the dental exam is something only your dentist can perform (CDA, The Dental Exam). Your dentist or hygienist may measure your gums (ODA, Gum Disease).
Q: What does a dental check-up cost in Toronto without insurance? Using the 2026 ODA fee-guide figures, as publicly reported in our post on the real cost of dental care in Toronto, a routine adult exam and cleaning lands roughly $250 to $400, depending on cleaning time and X-rays. That's a ballpark, not a set price. The ODA notes dentists set their own fees, which can be above or below the guide (ODA, Dental Costs Explained).
Q: Is a dental check-up covered by the Canadian Dental Care Plan? Yes, if you're eligible for the CDCP. The plan covers dental exams, X-rays, cleaning (scaling) and fluoride under diagnostic and preventive services (Government of Canada, CDCP coverage). Its benefits guide limits a recall examination to 1 in any 12 months and a complete oral examination to 1 in any 60 months (5 years), counted on rolling periods (CDCP Dental Benefits Guide). The plan pays its own established fees, which can differ from an office's fee, and our post on OHIP and insurance explains eligibility and how that works. Our post on what the CDCP covers for cleanings and exams has more detail.
