A deep dental cleaning, also called scaling and root planing, removes hardened tartar and bacteria from below the gumline and smooths the tooth roots so your gums can heal and tighten back around the teeth. It’s done with local freezing, usually over 1 or 2 visits, and it’s the standard first treatment for early to moderate gum disease. Gum disease is very common and treatable, but it doesn’t reverse by brushing harder, which is why deep cleaning sits right next to routine preventive care in most treatment plans.
If you’ve just been told you need one, you’re far from alone. The Canadian Dental Association estimates that about 7 in 10 Canadians will develop gum disease at some point in their lives.
Some offices also use laser dentistry alongside traditional instruments to clean infected pockets and reduce bacteria. Ask the best dentist you can find to explain which method fits your gums and why.
Treating gum disease early protects the bone that holds your teeth. Once enough bone is lost, teeth loosen, and replacing them later with dental implants gets more complicated. Patients enrolled in the CDCP can ask what periodontal care their plan includes. And if you’re ready to get your gums checked, our online booking takes about a minute.
In plain terms
Scaling scrapes tartar and plaque off the tooth surface above and below the gums. Root planing smooths the root surface so bacteria have a harder time sticking and the gum can reattach. Together, they treat the infection that causes periodontal pockets.
How is a deep cleaning different from a regular cleaning?
A regular cleaning (prophylaxis) is maintenance for healthy gums. It focuses on the visible parts of your teeth and just slightly below the gum edge.
A deep cleaning goes after infection. It reaches into pockets that have formed between the gum and the root, sometimes 5 mm deep or more.
| Regular cleaning | Deep cleaning | |
|---|---|---|
| Purpose | Prevention for healthy gums | Treating gum disease |
| Area cleaned | Above and just below the gumline | Deep into gum pockets, along the roots |
| Freezing | Usually not needed | Usually used |
| Visits | 1 | 1 to 2, often by section of the mouth |
| Follow-up | Next routine checkup | Re-check in 4 to 6 weeks, then closer maintenance |
Who needs a deep dental cleaning?
Your dentist or hygienist measures the space between your gums and teeth with a small ruler called a periodontal probe. Healthy pockets are usually 1 to 3 mm.
A deep cleaning is typically recommended when:
- Pockets measure 4 mm or more and bleed when probed
- X-rays show bone loss around the roots
- There’s tartar buildup below the gumline
- Gums are swollen, red, or pulling away from the teeth
- Teeth feel loose or bad breath won’t go away
Gingivitis, the early stage, can often be reversed with a regular cleaning and better home care. Periodontitis, the stage where bone and attachment are lost, needs deep cleaning.
What happens during the appointment? Step by step
- Assessment. Your gums are measured, X-rays are reviewed, and the plan is explained. Many offices treat 1 or 2 quadrants (quarters) of the mouth per visit.
- Freezing. Local anesthetic numbs the area so the cleaning is comfortable.
- Ultrasonic scaling. A vibrating tip with water spray breaks up hard tartar and flushes bacteria out of the pockets.
- Hand scaling. Fine instruments remove the remaining deposits along each root.
- Root planing. The root surfaces are smoothed so gum tissue can reattach more easily.
- Optional extras. Depending on the case, the pockets may be rinsed with an antimicrobial, treated with a laser, or given a local antibiotic placed directly into deep pockets.
- Aftercare instructions. You’ll go home with clear guidance on brushing, rinsing and what to expect.
Each visit usually takes 45 minutes to 1.5 hours, depending on how much needs to be done.
Does a deep cleaning hurt?
With freezing, most patients feel pressure and vibration but not pain during the procedure.
Afterward, it’s normal to have:
- Gum tenderness for 1 to 3 days
- Mild bleeding when brushing for a few days
- Tooth sensitivity to cold, which can last a few weeks
- Slightly more visible roots as swelling goes down (the gums were puffy before, so this is them getting healthier)
Over-the-counter pain relief and warm salt water rinses usually handle the discomfort.
Safety note: Call your dental office if you develop fever, swelling that gets worse after 2 days, pus, or bleeding that won’t stop with gentle pressure. People with certain heart conditions, joint replacements or immune concerns should tell their dentist before treatment, since antibiotics or other precautions may be needed.
What results can you expect?
Deep cleaning stops the active infection in most early and moderate cases. Studies show pocket depths commonly drop by around 1 to 2 mm as the gum tightens.
At your re-evaluation 4 to 6 weeks later, your gums are measured again. Usually you’ll see less bleeding, shallower pockets and firmer gums.
If some deep pockets remain, your dentist may suggest more targeted treatment or a referral to a periodontist (a gum specialist).
Aftercare: the first week and beyond
First 24 hours
- Wait until the freezing wears off before eating
- Stick to soft, lukewarm foods
- Skip smoking and alcohol
Days 2 to 7
- Brush gently with a soft brush, twice a day
- Start flossing again, carefully
- Rinse with warm salt water a few times a day
- Use a sensitivity toothpaste if cold bothers you
Long term
- Book periodontal maintenance cleanings, often every 3 to 4 months instead of every 6
- Use interdental brushes or a water flosser if spaces between teeth have opened up
- Get help to quit smoking, since it’s one of the strongest risk factors for gum disease
- Keep diabetes well controlled if you have it, as blood sugar and gum health affect each other
Deep cleaning vs gum surgery: what’s the difference?
Patients sometimes worry that a deep cleaning is the first step toward surgery. For most people, it’s the only step they need.
| Scaling and root planing | Periodontal surgery | |
|---|---|---|
| When used | Early to moderate periodontitis | Advanced disease or pockets that stay deep after deep cleaning |
| Approach | Cleaning through the pocket without cutting | Gum is opened to clean roots and reshape bone or tissue |
| Who does it | General dentist or hygienist | Usually a periodontist |
| Recovery | A few days of tenderness | 1 to 2 weeks, sometimes stitches |
| Typical order | First-line treatment | Only if non-surgical care is not enough |
A quick self-check: signs your gums need attention
Run through this list. If 2 or more apply, it’s worth booking a gum assessment.
- Your gums bleed when you brush or floss, most days.
- Your gums look red, puffy or shiny instead of firm and pink.
- Your breath stays bad even after brushing.
- Your teeth look longer than they used to.
- Food gets stuck in new places between teeth.
- Your bite feels different, or a tooth feels slightly loose.
- It’s been more than a year since your last professional cleaning.
Does gum disease affect the rest of your body?
Research has linked periodontitis with several health conditions, including diabetes, heart disease and complications in pregnancy. The connection runs through inflammation and bacteria entering the bloodstream from infected gums.
The link with diabetes is the clearest. Poorly controlled blood sugar makes gum disease worse, and treating gum disease can help with blood sugar control in some people.
Researchers are still working out cause and effect for the other conditions. But keeping your gums healthy is a sensible part of looking after your overall health, and your dentist may ask about your medical history for exactly this reason.
Myths about deep cleanings
Myth: Deep cleaning damages your teeth
Scaling removes tartar and smooths roots. It doesn’t remove healthy enamel. Some temporary sensitivity is common, but the long-term effect is healthier gums.
Myth: Deep cleaning makes gums recede
Gums can look lower afterward because the swelling has gone down. The tissue was inflamed before. The infection is what destroys gum and bone, and treatment slows or stops that.
Myth: If my gums don’t hurt, I don’t have gum disease
Gum disease is often painless until it’s advanced. Bleeding gums and bad breath are much more reliable warning signs than pain.
Myth: A good electric toothbrush can fix it
Home care keeps gums healthy after treatment. It can’t reach hardened tartar deep in a pocket. Only professional instruments can remove that.
Situations we see often
The busy parent. Someone skipped cleanings for 4 years while raising young kids. Their gums bleed every time they floss. Probing shows 5 mm pockets in a few spots. Two visits of deep cleaning, then a 3-month maintenance schedule, and at re-check their bleeding is down sharply.
The smoker with “fine” gums. Smoking can hide bleeding by reducing blood flow. This patient’s gums looked pale and firm, but X-rays showed bone loss. Deep cleaning plus a plan to quit made the difference.
The mild case. A third patient worried they’d need a deep cleaning, but their pockets were 3 mm with light bleeding. A regular cleaning and better flossing sorted it out.
Why licensed care matters for gum treatment
In Ontario, dentists must be registered with the Royal College of Dental Surgeons of Ontario (RCDSO), and dental hygienists are regulated by their own college. That oversight covers how gum disease is diagnosed, how procedures are done and how infection control is handled.
A proper diagnosis includes full probing, X-rays and a written plan. Be cautious of anyone who recommends a deep cleaning without measuring your gums first.

Frequently asked questions
How long does a deep dental cleaning take?
Each visit usually takes 45 minutes to 1.5 hours. Many offices split treatment into 2 visits, cleaning half the mouth each time, so you’re not frozen on both sides at once.
Can I eat after a deep cleaning?
Yes, once the freezing wears off. Stick to soft, lukewarm foods for the first day and avoid very hot, spicy or crunchy foods while your gums are tender.
How often do I need a deep cleaning?
Usually it’s a one-time treatment followed by regular maintenance cleanings every 3 to 4 months. If gum disease returns, another round may be needed in specific areas.
Is gum disease contagious?
The bacteria involved can be shared through saliva, but whether someone develops gum disease depends mostly on their own oral hygiene, genetics, smoking and overall health.
What happens if I don’t get a deep cleaning?
Untreated periodontitis usually keeps progressing. Over time it can destroy the bone that supports your teeth, causing gum recession, loose teeth and eventually tooth loss.
Conclusion
A deep cleaning removes infection from below the gumline so your gums can heal and tighten.
It’s done with freezing, the soreness is short, and the results protect your teeth for years.
