How often should you see a dentist?

Reviewed by Dr. Samar Fadavi, DDS

Short answer: Many people do well with a check-up and cleaning about every six months, but the right interval depends on your own risk. People with gum disease, frequent cavities, diabetes, dry mouth or braces may need visits every three to four months, while people with very healthy mouths may be seen less often. Children should see a dentist by their first birthday.

Why there is no single answer

The familiar “every six months” advice is a good starting point, not a rule that fits everyone. Your mouth is not the same as your neighbour’s. Some people build hard tartar quickly, some have gums that bleed easily, some take medicines that dry the mouth, and some go years without a cavity. A visit schedule that matches your own risk catches problems early without asking you to come in more than you need.

This guide explains how dentists decide how often you should come in, what happens at a regular visit, how the schedule changes for children, teens, adults, pregnant patients and seniors, and why skipping visits often costs more time and comfort later. It is general information for families in Scarborough, the Danforth and East Toronto. Our family dentistry page explains check-ups at our clinic.

What decides your visit schedule

At your exam, the dentist and hygienist look at several things and suggest a recall interval, the time until your next check-up and cleaning:

• Gum health. Bleeding gums, deep pockets or bone loss mean gum disease is active or likely, which needs more frequent cleanings.
• Cavity history. New cavities in the past year or two point to higher risk.
• How fast tartar builds up. Some people form hard deposits quickly, even with good brushing.
• General health. Diabetes, heart conditions, a weakened immune system and pregnancy affect the gums and healing.
• Medicines. Many medicines reduce saliva, which raises the risk of decay. Our guide on dry mouth and medications after 60 explains this in detail.
• Smoking and vaping. Both raise the risk of gum disease and oral cancer and stain the teeth.
• Diet. Frequent sugary snacks and drinks, or acidic drinks sipped through the day.
• Dental work. Crowns, bridges, implants, braces and dentures all need regular checks.
• Home care. How well plaque is removed between visits.

Typical visit schedules

Every three to four months

Often suggested for people with gum disease that has been treated, people with diabetes or other conditions that affect the gums, smokers with signs of gum problems, people who build tartar quickly, and some people with braces or many crowns and bridges. Short intervals keep bacteria below the gum line under control and protect the bone around the teeth.

Every six months

Suits many children, teens and adults with a moderate risk of cavities or gum problems. It allows small cavities, early gum changes and worn fillings to be found and treated while they are small.

Every nine to twelve months

Sometimes suggested for adults with very healthy gums, no recent cavities, low tartar build-up and good home care. Even then, a yearly exam with an oral cancer screening is important.

Your interval can change. If gum disease settles, your visits may become less frequent. If new medicines dry your mouth or cavities appear, the dentist may suggest coming in more often for a while.

What happens at a regular check-up and cleaning

1. Health update. Changes in your health, medicines and any concerns.
2. Exam. The dentist checks each tooth, fillings, crowns, the bite and the jaw joints.
3. Gum check. Measuring the pockets around the teeth to track gum health.
4. Oral cancer screening. A look and feel of the tongue, cheeks, floor of the mouth, palate, lips and neck. Our guide on oral cancer explains what is checked.
5. X-rays when needed. Not every visit. Our guide on dental x-rays explains how often they are taken and why.
6. Cleaning. Removing plaque and tartar above and just below the gum line, then polishing.
7. Fluoride when it helps, especially for people at higher risk of cavities.
8. Advice and a plan. Tips for home care and, if anything was found, treatment options with a written estimate.

Our guide on what type of dental exam you need explains the difference between a complete exam, a recall exam and an emergency exam.

Why regular visits matter even when nothing hurts

Most dental problems do not hurt at first. Early cavities, gum disease, cracks, worn fillings and oral cancer often cause no pain until they are advanced. By the time a tooth aches, a small filling may have turned into a root canal or a crown. Regular visits:

• Find cavities while they are small and easy to fill. Our guide on how dentists find cavities early explains the methods.
• Remove tartar that brushing cannot remove.
• Catch gum disease before it damages the bone. Our guide on gum bleeding explains early warning signs.
• Check fillings, crowns and implants for wear or leaks.
• Screen for oral cancer.
• Give you a chance to ask questions and adjust your home care.

Our guide on why regular dental visits matter covers these benefits in more depth.

How often children should see the dentist

Children should have their first dental visit by their first birthday or within six months of the first tooth appearing. After that, most children are seen about every six months. Visits check growth, look for early cavities, apply fluoride and sealants when helpful and teach brushing habits. Children with frequent cavities may need visits every three to four months. Our guide on your child’s first dental visit explains what to expect, and our children’s dentistry page explains care at our clinic.

Teens and young adults

Teens often snack more, drink sports drinks and pop, and may have braces, all of which raise the risk of cavities and gum inflammation. Wisdom teeth also start to develop and are watched with x-rays. Most teens do well with visits every six months, and more often while wearing braces.

During pregnancy

Hormone changes can make gums swell and bleed more easily. A check-up and cleaning during pregnancy is safe and recommended, often in the second trimester. Some people benefit from an extra cleaning during pregnancy. Our guide on pregnancy and oral health has more detail.

Older adults and denture wearers

Older adults often have more fillings and crowns, gum recession, dry mouth from medicines and a higher risk of root cavities and oral cancer. Many benefit from visits every three to six months. People who wear full dentures still need a yearly exam to check the gums, the fit of the denture and screen for oral cancer, even with no natural teeth. Our seniors’ dental care page explains care for older patients.

People with health conditions

• Diabetes: gum disease and diabetes affect each other; more frequent cleanings are often suggested.
• Heart conditions: regular care keeps gum inflammation low. Our guide on heart conditions and dental care explains what to tell the dentist.
• Cancer treatment: a dental exam before treatment and close follow-up during and after helps prevent problems.
• Weakened immune system: infections can be more serious, so early detection matters.

What if it has been years since your last visit?

You are not alone, and there is no need to feel embarrassed. Many people put off the dentist because of cost worries, busy schedules or anxiety. The first visit back usually includes a full exam, x-rays and a plan. If there is a lot of tartar, the cleaning may be split into two or more visits. The team will explain what they find and help you plan treatment in steps. If you feel nervous, tell the team; our guide on how anxious you are at the dentist can help you describe your worries, and our dental anxiety page explains how we help nervous patients.

Insurance, CDCP and visit frequency

Many insurance plans cover check-ups and cleanings at set intervals, such as every six or nine months, and limit how many units of scaling are covered each year. The Canadian Dental Care Plan also has its own rules for preventive visits. The interval your dentist recommends is based on your health, not on your plan, but the team can help you understand what your plan covers and give you a written estimate. Our guide on how dental insurance works in Canada and our CDCP dentist page explain coverage.

Making regular visits easier

• Book your next visit before you leave the clinic.
• Choose evening or Saturday hours if weekdays are hard. The clinic is open Monday, Wednesday, Thursday and Friday 10 am to 7 pm, Tuesday 1 pm to 5 pm and Saturday 10 am to 4 pm.
• Book family members back to back.
• Ask for reminders by text or email.
• Tell the team about anxiety, mobility needs or language preferences. The clinic is wheelchair accessible, and the team speaks English, French, Farsi and ASL.

Make the most of each visit

• Bring an updated medicine list, including vitamins and over-the-counter products.
• Write down questions before you come, such as a sensitive spot or a change in your bite.
• Mention changes in your health, such as a new diagnosis, pregnancy or recent surgery.
• Ask what your gum measurements mean and whether they are improving.
• Ask to see your x-rays if something was found, so you understand the plan.
• Ask for one or two home care changes that would help you most, rather than a long list.

Habits that keep the time between visits healthy

• Brush twice a day for two minutes with fluoride toothpaste, and spit instead of rinsing.
• Clean between your teeth once a day with floss, picks or interdental brushes. Our guide on why flossing matters shows how.
• Keep sugary and acidic foods and drinks to mealtimes.
• Drink water through the day, especially if your mouth feels dry.
• Do not smoke or vape.
• Wear a mouthguard for contact sports and a night guard if you grind.
• Replace your toothbrush every three months.

When to see a dentist between check-ups

Do not wait for your next scheduled visit if you notice:

• Tooth pain, sensitivity that keeps getting worse, or pain when biting.
• Bleeding, swollen or receding gums.
• A loose adult tooth.
• A sore, lump or patch in the mouth that does not heal within two weeks.
• A broken tooth, filling or crown.
• Swelling of the face or gum.

Questions about how often to see the dentist

Is once a year enough?

For some adults with very healthy mouths, yes. Many people need visits more often. Your dentist will suggest an interval based on your gums, cavity history and health.

Why does my hygienist want to see me every three months?

Usually because of gum disease or fast tartar build-up. Bacteria below the gum line regrow in about three months, so shorter intervals keep them under control.

Do I need a check-up if I have no teeth?

Yes. A yearly visit checks the gums, the fit of your dentures and screens for oral cancer.

Do I need x-rays at every visit?

No. X-rays are taken based on your risk, often every one to two years for adults with low risk.

Can I skip the cleaning if I brush and floss well?

Good home care helps a lot, but brushing cannot remove hardened tartar. Professional cleanings are still needed.

When should my child first see a dentist?

By the first birthday or within six months of the first tooth appearing.

Do I need a check-up if I wear braces or aligners?

Yes. Orthodontic visits adjust the braces or aligners, but they do not replace check-ups and cleanings. Brackets and aligners trap plaque, so many people with braces benefit from visits every three to four months.

How often should someone with implants be seen?

Implants need regular checks just like natural teeth. The gum and bone around an implant can become inflamed, so the dentist checks them and cleans around the implant with tools made for it, usually every three to six months.

Can I book my whole family on the same day?

Often, yes. Ask the team for back-to-back visits; evening and Saturday times are popular, so booking a few weeks ahead helps.
