Is Deep Cleaning Good or Bad for Gum Disease?
Deep cleaning — known clinically as scaling and root planing — is widely considered the gold-standard, non-surgical treatment for gum disease (periodontal disease). When performed by a licensed dental professional, it is far more beneficial than leaving gum disease untreated. Like most dental treatments, it does come with temporary side effects that patients in Calgary NW should understand before proceeding.
What Is Deep Cleaning (Scaling and Root Planing)?
A standard dental clean removes plaque and tartar from the surfaces of your teeth above the gum line. Deep cleaning goes further — it addresses both above and below the gum line, targeting the bacteria and deposits that drive periodontal disease.
Deep cleaning consists of two closely related steps:
- Scaling: The removal of plaque (a sticky film of bacteria and food debris) and calculus (hardened, mineralised tartar deposits) from both the supragingival (above the gum) and subgingival (below the gum) surfaces of the teeth.
- Root planing: The smoothing of rough root surfaces beneath the gum line using fine scalers and ultrasonic instruments. This creates a clean, smooth surface that allows inflamed gum tissue to reattach firmly to the tooth root.
Together, these two steps form the foundation of non-surgical periodontal care — the first and most important line of defence against advancing gum disease.
What Are the Goals of Scaling and Root Planing?
After a course of deep cleaning, your dental team will be working toward the following outcomes:
- Gum tissue that is firm, pink, and healthy — with no bleeding or redness
- A reduction in the depth of periodontal pockets (the spaces that form between the teeth and gums as disease progresses)
- Slowing or halting the loss of bone and connective tissue around the teeth
- Reducing the likelihood that surgical periodontal treatment will be necessary
Routine professional teeth cleaning is important for maintaining oral health, but it cannot reach the bacteria deep within periodontal pockets. Deep cleaning is specifically designed to address this.
What Side Effects Should You Expect After Deep Cleaning?
Deep cleaning is a safe and evidence-based procedure. However, there are a few temporary side effects that patients should be prepared for:
Tooth Sensitivity
It is common to experience temporary sensitivity to cold air or cold liquids after scaling and root planing. This typically settles within a few days to a couple of weeks as the gum tissue heals. Your dental hygienist may recommend a sensitivity toothpaste or a fluoride treatment to help manage discomfort during recovery.
Gum Recession and Spacing Between Teeth
As your gums heal and inflammation subsides, you may notice that your gum line appears to have receded slightly, or that small spaces have opened up between your teeth. This can be alarming if you are not expecting it — but it is actually a positive sign. What you are seeing is swollen, diseased tissue returning to its natural, healthy size. Inflamed gums are enlarged gums; as the infection resolves, the tissue tightens and shrinks back.
While this change in appearance may take some adjustment, it is always preferable to leaving gum disease inadequately treated, which can lead to progressive bone loss, loose teeth, and ultimately tooth loss.
Is Deep Cleaning Painful?
Most patients find scaling and root planing manageable, especially when local anaesthetic is used to numb the area being treated. For patients who experience significant dental anxiety, our team at Expressions Dental offers a range of comfort options, including nitrous oxide sedation, to help you feel relaxed throughout the procedure. Please let us know your concerns — we will tailor your care accordingly.
How Does Deep Cleaning Fit Into Your Overall Periodontal Treatment Plan?
Scaling and root planing is typically the first active treatment for moderate to advanced gum disease. After your deep cleaning appointments, your dentist or dental hygienist will reassess your periodontal health — usually four to eight weeks later — to measure pocket depths and evaluate how well your gums have responded.
Depending on results, your ongoing care may include:
- More frequent periodontal maintenance visits (typically every three to four months rather than the standard six-month recall)
- Adjunctive antimicrobial therapy
- Referral to a periodontist if surgical intervention is warranted
Ongoing support from a licensed dental hygienist in Calgary is an essential part of keeping gum disease under control after deep cleaning.
Who Needs Deep Cleaning?
Deep cleaning is recommended when a patient has been diagnosed with periodontitis — a more advanced form of gum disease that has progressed beyond simple gingivitis. Signs that you may need scaling and root planing include:
- Gums that bleed regularly when brushing or flossing
- Persistent bad breath that does not resolve with brushing
- Gum tissue that looks red, swollen, or pulls away from the teeth
- Periodontal pocket depths of 4mm or greater (measured by your dentist or hygienist)
- Visible tartar build-up below the gum line on X-rays
If any of these signs sound familiar, it is important not to delay seeking care. Gum disease is progressive — the earlier it is treated, the better the outcome.

Frequently Asked Questions
Is deep cleaning (scaling and root planing) actually good for gum disease?
Yes — scaling and root planing is the most effective non-surgical treatment for periodontal (gum) disease. It removes the bacterial deposits that cause inflammation and bone loss, and allows the gum tissue to heal and reattach to the tooth roots. Without treatment, gum disease will continue to progress and may eventually result in tooth loss.
Does deep cleaning hurt?
Most patients experience little to no pain during deep cleaning because local anaesthetic is used to numb the area being treated. Some tenderness and sensitivity may be felt for a few days afterward, but this is temporary. Patients with dental anxiety can also ask about sedation options, such as nitrous oxide, to make the experience more comfortable.
Why do my gums look like they have receded after deep cleaning?
What appears to be gum recession after deep cleaning is usually your gums returning to their natural, healthy size. Diseased gums are swollen and enlarged due to inflammation. As the infection resolves and healing takes place, the tissue tightens and shrinks — which can make your gum line look lower. This is a normal and positive sign of healing.
How many deep cleaning appointments will I need?
Most patients require two to four appointments for scaling and root planing, typically divided by quadrant (one quarter of the mouth at a time) or by half. This allows your dental team to work thoroughly in each area while keeping each appointment manageable. The exact number of visits depends on the severity of your gum disease.
Will my teeth be sensitive after deep cleaning?
Yes, temporary sensitivity to cold air or cold liquids is common after scaling and root planing. This usually resolves within one to two weeks as your gums heal. Your dental hygienist may recommend a sensitivity toothpaste or apply a fluoride treatment at your appointment to help minimise discomfort.
Can gum disease come back after deep cleaning?
Gum disease can return if oral hygiene habits are not maintained. After deep cleaning, your dental team will likely recommend more frequent professional cleanings — every three to four months — to keep periodontal disease under control. Consistent brushing, flossing, and regular dental visits are essential for long-term success.
How do I know if I need a deep cleaning rather than a regular cleaning?
Your dentist or dental hygienist will measure the depth of the pockets around each tooth during a periodontal examination. Pocket depths of 4mm or greater, combined with signs of bone loss or inflammation, typically indicate that a deep cleaning is needed rather than a standard hygiene appointment. If you are unsure about your gum health, book an assessment at Expressions Dental in Calgary NW.
