Deep Cleaning Teeth Cost in Toronto: What to Expect

If your dentist just told you that you need a deep cleaning instead of your usual cleaning, it is normal to have questions, starting with what it is going to cost. A deep cleaning, known clinically as scaling and root planing, treats early to moderate gum disease before it turns into something more serious. Here is what it actually costs for GTA patients, what changes the price, and what to expect at your appointment.

What Is a Deep Cleaning (Scaling and Root Planing)?

A regular cleaning removes plaque and tartar from the surface of your teeth and just above the gumline. A deep cleaning goes further. It removes buildup from below the gumline and smooths the root surfaces so your gums can reattach to your teeth. Dentists recommend it when a checkup shows early signs of gum disease, usually gum pockets deeper than 4 millimetres, or bleeding and inflammation that a regular cleaning will not resolve.

Deep Cleaning Cost in Toronto

Deep cleaning is billed per quadrant, meaning your mouth is divided into four sections and each one is priced separately. Most patients need two to four quadrants treated, sometimes spread across more than one visit so you are not numb on both sides of your mouth at once.

Quadrants Treated	Average Cost (CAD)	Typical Visits Needed
1 quadrant	$150 to $280	1 visit
2 quadrants	$300 to $560	1 to 2 visits
Full mouth (4 quadrants)	$600 to $1,100+	2 to 4 visits

These ranges reflect typical GTA pricing in 2026, and they will vary somewhat from clinic to clinic depending on whether local anaesthetic, a re-evaluation visit, or antimicrobial treatment is included in the quoted price. Your exact number depends on how much buildup there is below the gumline and how many quadrants are affected.

What Affects the Price at Your Dentist

• How advanced the gum disease is and how many quadrants need treatment

• Whether local anaesthetic is used during the procedure

• Whether you need a separate re-evaluation visit four to six weeks later

• Whether antimicrobial treatment is placed in deeper pockets

• Your dental insurance plan and how much of your annual coverage is left

Deep Cleaning vs a Regular Cleaning: What's the Difference?

A regular cleaning takes about 30 to 45 minutes and focuses on plaque above the gumline, which is ideal for patients with healthy gums. A deep cleaning is a different procedure entirely: more time, more depth, and it is only recommended once gum disease has already started. If your last checkup came back clean, you likely will not need one.

Does Insurance or CDCP Cover Deep Cleaning?

Most private dental plans in Ontario cover a portion of scaling and root planing, though the amount varies by provider and plan. If you are enrolled in the Canadian Dental Care Plan, scaling procedures fall under a combined annual cap of 4 units for adults, so how much is covered depends on what else you have used from that benefit year. We check your coverage and give you a clear estimate before any work starts, so there are no surprises on your bill.

What Happens If You Skip It?

Untreated gum disease does not stay put. It progresses from gingivitis to periodontitis, where the bone loss around your teeth becomes permanent and teeth can eventually loosen or fall out. The effects reach beyond your mouth too, with real connections to broader health risks, so treating gum disease early is worth more than just the appointment itself.

Signs You Might Need a Deep Cleaning

You may not notice gum disease developing on your own, since early stages rarely hurt. Between visits, watch for these signs: bleeding when you brush or floss, gums that look red or puffy, persistent bad breath, or teeth that suddenly feel loose. If your last exam mentioned pocket depths, that is your dentist already tracking early gum disease before it becomes visible to you.

What to Expect at Your Appointment

Most deep cleanings start with a topical or local anaesthetic so you are comfortable while the hygienist works below the gumline. You might feel some tenderness or mild sensitivity for a day or two afterward, similar to a very thorough cleaning. Your dentist will usually book a follow-up four to six weeks later to check how your gums have healed and confirm pocket depths have improved before deciding if any further treatment is needed.

Common Questions About Deep Cleaning

Is a deep cleaning painful?

Most patients feel pressure rather than pain, since local anaesthetic numbs the area beforehand. Mild soreness or sensitivity for a day or two afterward is normal, and over-the-counter pain relief along with a saltwater rinse usually covers it.

How many appointments does a full deep cleaning take?

Most patients need two to four visits, treating one or two quadrants at a time so you are not numb on both sides of your mouth in a single appointment. Full-mouth cases sometimes stretch across a few weeks.

Will I need a deep cleaning again in the future?

Possibly. Once you have had gum disease, you are more likely to need more frequent maintenance cleanings, often every three to four months instead of the usual six, to keep it from coming back and to catch any new problem areas early.

What happens if I can't afford the full treatment right now?

Talk to us before skipping it. We can often prioritize the areas with the deepest pockets first and space out the remaining quadrants, or set up a payment plan so gum disease does not get worse while treatment is spread over time.
