Deep Cleaning vs Scaling & Polishing Singapore (2026)

Deep cleaning — clinically known as Scaling and Root Planing (SRP) or periodontal debridement — is a therapeutic procedure prescribed when you have gum disease (periodontitis). Unlike regular S&P, it targets the bacteria, tartar, and toxins that have accumulated in the periodontal pockets below your gumline and on the roots of your teeth.

During SRP, your dentist or periodontist uses specialised hand scalers and/or ultrasonic instruments to clean root surfaces and smooth them out (root planing), removing bacterial deposits and creating a clean surface for your gums to reattach. Local anaesthesia is almost always administered, as the procedure can be uncomfortable without it. Treatment is usually split across multiple appointments — typically by quadrant (one quarter of the mouth per visit).

SRP is indicated when periodontal pocket depths measure 4mm or more, when there is bleeding on probing, bone loss visible on X-rays, or when regular S&P has failed to resolve gum inflammation. In Singapore, this procedure is performed by general dentists or specialist periodontists, and it IS claimable under Medisave for eligible cases.

The most critical distinction between the two procedures is the depth of treatment and the clinical reason for it. Regular S&P is preventive — it maintains healthy gums and clean teeth in patients without significant gum disease. Deep cleaning is therapeutic — it treats an active infection in the gum tissue and bone supporting your teeth.

In terms of the experience: regular S&P is quick, relatively painless, and requires no anaesthesia for most patients. Deep cleaning involves local anaesthesia injections, takes longer (often 1–2 hours per quadrant), and is followed by a recovery period of 1–2 days where gums may feel sore and swollen. Your dentist will also schedule a review appointment 4–6 weeks later to assess whether gum pockets have reduced.

• A key fear many patients have is: 'Will deep cleaning damage my teeth or make my gums recede more?' The answer is no — deep cleaning does not cause recession; it reveals recession that was already masked by inflamed, swollen gum tissue. Untreated periodontitis, on the other hand, will cause progressive and irreversible bone and gum loss, ultimately leading to tooth loss.

Your dentist will assess your gum health during a periodontal examination, which includes probing each tooth at six points to measure pocket depth in millimetres and checking for bleeding on probing. A full-mouth X-ray (periapical or OPG) may also be taken to assess the level of bone support around your teeth.

If pocket depths are generally ≤3mm with minimal bleeding, regular S&P is appropriate. If pockets are 4mm or deeper — particularly with bleeding, bone loss, or visible tartar below the gumline — you will be diagnosed with periodontitis and deep cleaning will be recommended. Some patients are surprised or even sceptical when told they need SRP, especially if they have no pain. However, periodontitis is largely painless in its early and moderate stages, which is exactly why it is often under-diagnosed until significant damage has occurred.

In Singapore's private dental sector, some less scrupulous clinics may over-prescribe deep cleaning for commercial reasons. A good rule of thumb: always ask your dentist to show you the periodontal chart and explain which specific pockets are ≥4mm before consenting to SRP. A second opinion from a polyclinic dentist or a MOH-registered periodontist is always a reasonable step if you are uncertain.

Regular scaling and polishing at private dental clinics in Singapore typically costs $60–$170 per session, depending on the clinic tier and the amount of tartar build-up. At polyclinics, fees are significantly lower at around $16.50–$19.20 for Singapore Citizens before subsidies. CHAS blue card holders may pay as little as $0–$5 for S&P at participating clinics.

Deep cleaning (SRP) is substantially more expensive, ranging from $200–$1,500 for a full-mouth treatment. The wide range reflects whether you are being treated at a general dental clinic versus a specialist periodontist, the number of quadrants involved, and the severity of your gum disease. Per quadrant, expect to pay $150–$400 at a private dentist and $300–$600 or more at a specialist periodontist.

Critically, Medisave can be used to offset the cost of deep cleaning in Singapore under the Medisave for Dental Surgical Procedures scheme — specifically when SRP is performed as a surgical periodontal procedure. Patients can typically claim $250–$650 per quadrant depending on complexity. Always confirm claimability with your clinic and verify your CPF Medisave balance before your appointment.

After regular S&P, most patients can return to normal diet and activities immediately. Some may experience 24–48 hours of mild sensitivity to cold, which resolves on its own. Your dentist will advise you to return in 6 or 12 months for your next maintenance session.

After deep cleaning, expect 2–5 days of gum soreness, swelling, and sensitivity. Your dentist will likely prescribe chlorhexidine mouthwash and possibly antibiotics if the infection was severe. A soft diet for the first 24–48 hours is recommended. A critical follow-up review is scheduled at 4–6 weeks post-SRP to re-probe your pockets and evaluate healing. If pockets remain deep (≥5–6mm) despite successful SRP, referral to a periodontist for surgical intervention may be warranted.

Long-term, patients who have been treated for periodontitis require more frequent maintenance visits — typically every 3–4 months rather than the standard 6–12 months — to prevent recurrence. This is called Supportive Periodontal Therapy (SPT) and is an ongoing commitment. Skipping these maintenance visits after SRP significantly increases your risk of disease relapse and eventual tooth loss.
