What is the difference between a regular and a deep cleaning?

A regular prophylaxis cleaning removes plaque and tartar from above and just below the gum line — it takes 45–60 minutes and is primarily preventive. A deep cleaning (scaling and root planing) goes 3–6 mm or more below the gum line to remove calculus from root surfaces and smooth them to help gums reattach. It is a treatment for periodontal disease, not a preventive measure.

How much does a deep cleaning cost?

Scaling and root planing is typically billed per quadrant (one quarter of the mouth). At $150–$350 per quadrant, a full-mouth deep cleaning costs $600–$1,400 without insurance. Most dental insurance plans cover deep cleaning at 50–80% when periodontal disease is documented with X-rays and pocket depth measurements.

Is a deep cleaning painful?

Your dentist will use local anesthesia for the deep cleaning, so the procedure itself should not be painful. Post-treatment soreness, gum tenderness, and light bleeding for 3–5 days are normal. Over-the-counter ibuprofen manages most discomfort effectively. Some patients experience temporary sensitivity to hot and cold as the gums reattach to the root surfaces.

Dental Deep Cleaning vs. Regular Cleaning: What's the Difference?

April 25, 2026

What Is a Regular Cleaning?

A routine prophylaxis (preventive cleaning) is what most people get twice a year at a dental checkup. A dental hygienist uses hand scalers and an ultrasonic scaler to remove:

Plaque: Soft bacterial film that accumulates daily
Calculus (tartar): Hardened mineralized plaque that cannot be removed by brushing

The hygienist works above and just below the gumline (to about 1–3 mm into the sulcus). The appointment finishes with polishing and a fluoride treatment. This is appropriate for patients with healthy gums or mild gingivitis (pocket depths of 1–3 mm).

What Is a Deep Cleaning?

A deep cleaning — officially called scaling and root planing (SRP) — is a non-surgical treatment for periodontal disease (gum disease). When gum disease progresses, pockets between the teeth and gums deepen to 4–6 mm or more, and bacteria colonize these spaces below the gumline where regular cleaning cannot reach.

During SRP, the hygienist or periodontist:

Numbs the gum tissue with local anesthetic (typically one or two quadrants per appointment)
Scales the root surfaces below the gumline to remove calculus deposits
Planes (smooths) the root surfaces so gum tissue can reattach more easily

Antibiotic medications (Arestin, PerioChip) may be placed directly into the pockets at the time of treatment for additional bacterial control.

How Your Dentist Determines Which You Need

The decision is based on a periodontal examination that includes:

Probing depths: A thin probe measures the depth of the pocket between tooth and gum at 6 points per tooth. Depths of 4 mm or more generally indicate the need for SRP.
Bone level X-rays: Bitewing and periapical X-rays show whether bone loss has occurred around the roots.
Bleeding on probing: Bleeding when the probe touches the pocket indicates active inflammation.
Calculus location: Subgingival (below the gum) calculus is visible on X-rays as calcified deposits.

Recovery After a Deep Cleaning

After each quadrant appointment:

Expect gum soreness and light bleeding for 3–5 days
Teeth may feel sensitive to cold for 1–2 weeks as gums recede slightly away from treated root surfaces
Use a soft-bristle toothbrush and avoid flossing aggressively in treated areas for the first 48 hours
Take ibuprofen as directed for discomfort — antibiotics are prescribed only if systemic infection signs are present

What Happens After the Deep Cleaning

A follow-up appointment 4–8 weeks later re-measures pocket depths to assess healing. Many patients with moderate gum disease (4–5 mm pockets) achieve stable, improved pocket depths with SRP alone and return to regular 3–4 month maintenance cleanings. Patients with severe disease (pockets over 6 mm, significant bone loss) may be referred to a periodontist for surgical evaluation.

The single most important factor in long-term success is daily home care — correct brushing technique (2 minutes, twice daily) and daily flossing or interdental brush use.
