At a dental checkup, expect a review of your health and any concerns, an examination of your teeth, gums and mouth, often a professional teeth cleaning, and a plain-language talk about what was found. Dental X-rays may be added, but only when your dentist needs information that cannot be seen during the exam, so not every visit includes them.
Key Takeaways
- A dental checkup is an examination and risk assessment: the dentist looks for changes in your teeth, gums, bite and oral tissues and decides whether anything needs treatment, monitoring or a change in home care.
- A teeth cleaning is a separate service that is often booked with the checkup. A hygienist removes plaque and tartar (calculus) that brushing and flossing leave behind.
- Dental X-rays are not automatic. The Canadian Dental Association says radiographs should be based on a clinical examination and a need for information that could affect diagnosis or treatment.
- You will get more from the visit if you mention pain, sensitivity, bleeding, medications and health changes at the start, and ask when you should return before you leave.
What is a dental checkup?
A dental checkup is a scheduled visit in which a dentist examines your mouth for signs of tooth decay, gum disease, wear, cracks, failing fillings and changes in the soft tissues, then compares what they see with your history. Its purpose is to find problems while they are small and to set a plan for prevention. A checkup is sometimes called a recall exam or a periodic oral examination.
Checkups are the core of general dentistry, the ongoing primary care most families rely on. A checkup is not the same as an appointment for a specific problem. If you book because a tooth hurts, the visit will usually focus on diagnosing that tooth first. A first visit with a new dentist is also different: it is usually longer and more detailed, because the dentist is building a baseline record rather than comparing with one.
What to expect at a dental checkup, step by step
Most routine checkups follow a similar order, although the sequence can change depending on your needs and on who you see first. The table below gives a quick overview; each step is explained underneath.
| Step | Who usually does it | What happens | Is it always included? |
|---|---|---|---|
| Health and dental history | Dentist, hygienist or assistant | Review of medications, conditions, allergies and new concerns | Yes |
| Clinical examination | Dentist | Teeth, fillings, gums, bite, jaw and oral tissues are checked | Yes |
| Gum (periodontal) check | Hygienist or dentist | Gum pockets and bleeding may be measured and recorded | Often, based on need |
| Teeth cleaning | Hygienist | Plaque and tartar removed, teeth polished | Often booked together |
| Dental X-rays or photos | Hygienist or assistant, prescribed by the dentist | Images of areas the eye cannot see | Only when indicated |
| Findings and plan | Dentist | Explanation of results, options and when to return | Yes |
1. Health history and your concerns
A checkup usually begins with questions about your health since your last visit. The team may ask about new diagnoses, medications, allergies, pregnancy, tobacco or vaping, recent hospital care and any dental work done elsewhere. Some medications reduce saliva or affect bleeding and healing, so these details can change both your cavity risk and how treatment is planned.
This is also the moment to describe anything you have noticed. Mention tooth pain, sensitivity to cold or sweets, bleeding when you brush, a dry mouth, jaw clicking, a sore that is slow to heal, or a change in how your teeth fit together. A symptom that comes and goes is still worth reporting, because its timing and triggers help the dentist know where to look.
2. The clinical examination
According to the Canadian Dental Association, a dental exam includes looking for damaged, missing or decayed teeth and checking the gums, previous dental work and signs of oral cancer or other growths. The dentist may also note tooth position, signs of grinding, the jaw joints and the condition of the tongue and cheeks. Some exams include feeling the neck for swollen glands.
The oral tissue check is quick and painless. It is a useful screening step, but a routine checkup cannot guarantee that every condition will be found early, and it does not replace a biopsy or specialist assessment when one is needed.
3. The gum check
Healthy gums fit snugly around each tooth. During a periodontal check, the hygienist or dentist may gently measure the small space between the gum and tooth and note any bleeding. Deeper measurements or bleeding can point to gingivitis or periodontitis. If the numbers change over time, your dentist may recommend a more detailed periodontal evaluation or a different kind of cleaning.
4. Images when they are needed
If the dentist needs to see between teeth, under fillings or around the roots, they may prescribe dental X-rays. Some offices also use an intraoral camera, a small pen-shaped camera that shows you a magnified photo of a tooth on a screen. Photos help explain visible findings, while X-rays show what is hidden inside or between teeth. The next section explains how the X-ray decision is made.
5. Findings and your plan
The checkup should end with a clear explanation. You should know whether anything needs treatment, what can be watched, what to change at home and when to come back. A finding does not always mean treatment has to start that day. Some conditions need prompt care, while others can be monitored and reassessed.
Do you need X-rays at every checkup?
No. Dental X-rays are taken to answer a clinical question, not because a set amount of time has passed. The Canadian Dental Association's position on the control of X-radiation in dentistry says a radiographic exam must be based on a clinical examination and a need for information not readily available from other sources. It also advises checking whether recent images from a previous dentist can be used and keeping the number of images to the minimum needed.
The American Dental Association similarly says there is no "one size fits all" interval for dental X-rays. The timing depends on your current oral health, age, disease risk and any signs or symptoms.
Factors that make X-rays more likely at a particular checkup include:
- new pain, swelling or an injury to a tooth;
- a recent history of cavities or gum disease;
- large or ageing fillings and crowns that need to be checked underneath;
- a child's developing teeth, or wisdom teeth that are coming in;
- planned treatment, such as a crown or an extraction, that needs root and bone information;
- no suitable recent images on file.
If X-rays are recommended, it is reasonable to ask what the dentist is looking for and how the result could change your care. Landmark Dental Care uses digital dental X-rays; for more about exposure and safety, see our guide to digital dental X-ray safety.
What happens during a teeth cleaning?
A teeth cleaning, sometimes called a scale and polish, removes the deposits that daily brushing and flossing miss. Plaque is a soft, sticky film of bacteria. When it is left in place, it hardens into tartar (calculus), which cannot be brushed off at home and tends to collect along the gumline and behind the lower front teeth.
A typical cleaning includes some or all of these steps:
- Scaling. The hygienist removes tartar from tooth surfaces and just under the gumline. This may be done with hand instruments, an ultrasonic scaler, or both. An ultrasonic scaler such as a Cavitron uses fast vibrations and a water spray to loosen deposits; the water also flushes debris away.
- Polishing. A gritty paste and a soft rotating cup smooth the surfaces and remove some surface stains.
- Flossing and home-care coaching. The hygienist may floss between the teeth and show you where your brush or floss is missing plaque.
- Fluoride, when indicated. A fluoride varnish or other product may be recommended for people at higher risk of decay.
A cleaning is not identical for every patient. The amount of tartar, gum inflammation, sensitivity and existing dental work all affect how it is done and how long it takes. Mild tenderness or slight bleeding afterward can happen when gums are inflamed and usually settles, but bleeding that continues or worsens should be reported. If you are sensitive, say so before the cleaning starts; the hygienist can adjust technique, pace and water temperature. Ask which instruments will be used if you have had a sensitive cleaning before.
A routine cleaning is designed for healthy or mildly inflamed gums. If the gum check shows deeper pockets or bone loss, the dentist may recommend periodontal treatment instead, which is sometimes called a deep cleaning. The difference is covered in cleaning vs. deep cleaning.
Checkup vs. cleaning — what's the difference?
Patients often use "checkup" and "cleaning" to mean the same appointment. They are related, but they do different jobs, and dental plans often list them as separate services.
| Dental checkup (exam) | Teeth cleaning | |
|---|---|---|
| Main purpose | Find and diagnose problems, assess risk, set a plan | Remove plaque, tartar and some stain |
| Usually done by | Dentist | Dental hygienist |
| What it can find | Decay, cracks, gum disease, bite and jaw issues, soft-tissue changes | Areas of heavy buildup or bleeding the hygienist can flag |
| What it does not do | Remove tartar | Diagnose cavities or other conditions |
| How often | Set by your risk and oral health | Set by your gum health and how quickly tartar forms |
In practice, the two are often scheduled together so that you make one trip. Your cleaning interval and exam interval do not always have to match, though. Someone with gum disease may need cleanings more often than full exams.
Checkups for children, pregnancy, seniors and nervous patients
The basic steps stay the same across ages, but the emphasis changes.
Children. The Canadian Dental Association recommends that infants be assessed within six months of the first tooth appearing or by one year of age. Early checkups are short and focus on how the teeth are coming in, cavity risk, feeding habits and brushing with the right amount of fluoride toothpaste. Older children may be offered sealants on the grooves of their back molars when appropriate.
Pregnancy. Tell the team if you are pregnant or planning to be. Hormonal changes can make gums more prone to bleeding and swelling, and Health Canada notes that regular checkups are especially important during pregnancy. Routine exams and cleanings are generally part of normal prenatal self-care; your dentist will consider timing and any need for X-rays with your pregnancy in mind.
Seniors and denture wearers. Older adults are more likely to have root-surface decay, gum recession, dry mouth from medications and older dental work that needs monitoring. If you wear a denture, bring it. The dentist can check the fit and the tissues underneath, which still need an exam even when no natural teeth remain.
Medical conditions. Diabetes, heart conditions, cancer treatment and medications that affect bleeding or bone can all change how a checkup and any treatment are planned. Bring an up-to-date medication list, including supplements.
Dental anxiety. If checkups make you nervous, say so when you book and again when you arrive. You can ask the team to explain each step before it happens, agree on a hand signal to pause, and schedule at a time of day when you feel less rushed.
Questions to ask before you leave
A useful checkup leaves you with a clear picture of your oral health. You do not need to remember every term, but you should know what, if anything, happens next.
- Did you find anything new since my last visit? Ask which findings are new, stable or still uncertain.
- Why are you recommending this X-ray or treatment? The answer should connect to a symptom, finding, risk or planning need.
- What are my options, including waiting? Ask about benefits, limits, alternatives and what could happen if you delay.
- What should I do differently at home? Ask for advice tied to where plaque, bleeding or wear was found.
- What will this cost, and what should I ask my plan? An estimate before non-urgent treatment helps you plan.
- When should I come back? The Canadian Dental Association says many people are seen about every six months, but your dentist may recommend more or less often. Our guide to how often you should go to the dentist covers how that interval is set.
When to book sooner than your next checkup
Do not wait for a routine appointment if something changes. Call a dentist promptly for tooth pain that lasts, swelling in the gums or face, a broken tooth, a lost filling or crown, gums that bleed more than usual, rising sensitivity, or a sore or patch in the mouth that has not healed within about two weeks.
Some symptoms need medical care first. Facial swelling that is spreading, difficulty breathing or swallowing, uncontrolled bleeding or a serious facial injury call for 911 or a hospital emergency department, not a routine dental booking. If you are unsure which setting fits, Landmark Dental Care's emergency dentistry page explains how urgent dental problems are handled.
Getting a dental checkup in Truro
Landmark Dental Care is a family general practice at 125 Queen St in downtown Truro, in a Victorian Queen Anne–style home. The practice sees patients from Truro, Bible Hill and across Colchester County, from young children to seniors, and offers checkups and new-patient exams, periodontal evaluation, hygiene visits with Cavitron ultrasonic cleaning, fluoride and sealants. Office hours are Monday to Friday, 8:30am to 5:00pm.
If you are coming to the practice for the first time, bring a list of your medications and allergies, any dental benefit information, and the name of your previous dentist so recent X-rays can be requested rather than retaken. Write down your questions in advance; it is easy to forget them once you are in the chair.
Public programs may help with the cost. Nova Scotia's Children's Oral Health Program, billed through MSI, covers basic dental care for children aged 14 and younger with a valid Nova Scotia health card; as of 2026, the province lists one routine exam per year among the covered services, and private insurance must be used first where it applies. The federal Canadian Dental Care Plan (CDCP) helps eligible residents who have no access to private dental insurance and an adjusted family net income under $90,000, as of 2026. Please call the office to confirm current CDCP participation and billing before your visit, and see our CDCP information page for more.
FAQ
How long does a dental checkup take?
It depends on whether you are a new or returning patient, whether a cleaning or X-rays are planned, and whether there is a concern to investigate. A first visit is usually longer than a routine recall, so ask the office when booking if you need to plan around a set time.
Will I get X-rays at every dental checkup?
No. Dental X-rays are prescribed according to your symptoms, history, risk and the images already on file. Your dentist should be able to tell you what a proposed X-ray is expected to show.
Is a dental checkup the same as a teeth cleaning?
Not quite. The checkup is the dentist's examination and risk assessment, while the cleaning removes plaque and tartar. They are often booked together, but your gum health may call for a different kind of cleaning or a separate appointment.
Does a teeth cleaning hurt?
Most people feel pressure, scraping or vibration rather than pain. Inflamed gums and exposed roots can be more sensitive, so tell the hygienist beforehand; they can change technique, slow the pace or pause as needed.
What should I do to prepare for a dental checkup?
Brush and floss as usual, bring your medication list and benefit details, and note any symptoms you have noticed. If you are a new patient, ask your previous dentist to send recent records or X-rays.
