How Often Should You See a Dentist? A GTA Guide

The Short Answer: Every Six Months, With Exceptions

Most dental offices, including ours, still recommend a checkup and cleaning every six months. That interval isn't arbitrary. It's roughly how long it takes plaque to harden into tartar a toothbrush can't remove, and how long a small problem, like the start of a cavity or early gum inflammation, can develop before it needs more than a simple filling to fix.

Six months is a starting point, though, not a rule that applies equally to everyone. Your actual risk of cavities and gum disease depends on your genetics, your habits, your diet, and conditions like diabetes or dry mouth. Two patients can be on completely different checkup schedules and both be doing the right thing for their mouths.

Why Twice a Year Became the Standard

The six-month interval comes from how quickly plaque turns into tartar and how quickly early decay or gum inflammation can progress. Plaque that isn't removed within a few days starts to harden. Once it's tartar, brushing and flossing at home can't touch it, and it needs a professional scaling to come off. Left long enough, tartar buildup along the gumline is what turns mild gum irritation into gum disease.

Six months also gives us a chance to catch cavities while they're still small enough to fix with a simple filling, rather than a crown or root canal after the decay reaches the nerve. It's the interval that balances catching problems early against the cost and time of visits most people don't need more often than that.

How Often You Actually Need to Go, By Risk Level

Your dentist should adjust your recall schedule based on your actual risk, not just default to six months for everyone. Here's roughly how that breaks down.

Risk Level	Who This Applies To	Recommended Frequency
Low risk	No cavities in recent years, healthy gums, consistent brushing and flossing	Every 9 to 12 months
Average risk	Occasional cavities, some plaque buildup, generally healthy gums	Every 6 months
Higher risk	History of gum disease, smoking, diabetes, dry mouth, frequent snacking	Every 3 to 4 months
Active gum treatment	Currently being treated for periodontal disease	Every 2 to 3 months
Kids and teens	Growing mouths, new adult teeth, possible orthodontic changes	Every 6 months
Pregnant patients	Hormonal changes increase gum inflammation risk	Every 6 months, sooner if gums bleed or swell

If you're not sure which category you fall into, that's a normal question to bring to your next appointment. It's easier for a dentist to set the right interval after actually looking in your mouth than to guess from a list.

Signs You Shouldn't Wait for Your Next Scheduled Visit

Some signs mean it's worth booking sooner, regardless of when your last cleaning was:

• Gums that bleed when you brush or floss

• A tooth that's suddenly sensitive to hot, cold, or sweet foods

• A filling or crown that feels loose or has a rough edge

• Persistent bad breath that brushing and mouthwash don't fix

• Jaw pain or clicking when you chew

• A mouth sore that hasn't healed after two weeks

Bleeding gums in particular are often the first sign of gum disease, not something to wait out. Our guide to signs of gum disease walks through what else to watch for and when it's time to come in.

What Skipping Checkups Actually Costs You

A missed cavity doesn't stay small. Left alone, it grows toward the nerve, and what would have been a straightforward filling turns into a root canal or a crown. Gum inflammation follows the same pattern. Caught early, it reverses with a good cleaning and better home care. Left alone, it can progress to gum disease that affects the bone holding your teeth in place. Our article on what happens when a cavity goes untreated covers that progression in more detail.

A routine dental cleaning appointment usually takes less than an hour. Catching up after years away, or treating a problem that grew because it went unnoticed, takes a lot more than that, in both time and cost.

What a Checkup Actually Involves

A typical checkup includes an oral exam, a professional cleaning to remove plaque and tartar, and x-rays when needed to check for problems that aren't visible, like decay between teeth or below the gumline. We'll also flag anything worth watching, like a spot of wear on a filling or early signs of gum recession, before it turns into something that needs treatment.

Frequently Asked Questions

Is it bad to go more than a year without seeing a dentist?

For most people, yes. A year gives cavities, gum inflammation, and worn or cracked fillings plenty of time to turn into bigger problems. If it's been over a year, it's worth booking a visit rather than waiting for pain to tell you something's wrong.

Does dental insurance in Ontario cover two checkups a year?

Most Ontario dental plans cover two checkups and cleanings per calendar year, though coverage varies by plan and employer. Check your policy or ask our front desk to confirm what your plan covers before you book.

Can I tell on my own if I need to come in sooner than scheduled?

Not always. Cavities and early gum disease often don't hurt until they're fairly advanced. Bleeding gums, new sensitivity, or a change in how your bite feels are worth mentioning, but a lot of what we catch at checkups has no symptoms yet.

What if it's been years since my last dental appointment?

Come in anyway. We won't judge the gap. The first visit will likely include a full exam, x-rays, and a thorough cleaning, and we'll build a plan from there based on what we actually find.
