Bottom line: A dental deep cleaning (scaling and root planing) costs $200–$400 per quadrant, or $800–$1,600 for a full mouth treatment. This is different from a routine cleaning and is a medical procedure for gum disease. Insurance typically covers 50–80% after your deductible when gum disease is documented.
Deep cleaning cost breakdown
| Scope of treatment | What's included | Cost range |
|---|
| Single quadrant | Upper right, upper left, lower right, or lower left | $200–$400 |
| Two quadrants (half mouth) | One appointment, half at a time | $400–$800 |
| Full mouth (4 quadrants) | Usually 2 appointments | $800–$1,600 |
| Local anesthesia | Often included, sometimes billed separately | $50–$150 extra |
| Periodontal re-evaluation | Follow-up 4–6 weeks later | $50–$150 |
| Arestin antibiotic | Antibiotic microspheres placed in pockets | $50–$100 per tooth |
Routine cleaning vs. deep cleaning: the key difference
A routine prophylaxis cleaning removes plaque and tartar from tooth surfaces above the gumline. A deep cleaning (scaling and root planing) goes below the gumline to remove tartar deposits from root surfaces and smooth root surfaces to discourage bacteria reattachment. It is a non-surgical treatment for gum disease, not an upgraded version of a regular cleaning.
Your hygienist measures gum pocket depth with a probe at every visit. Healthy pockets are 1–3mm. Pockets of 4mm+ indicate early gum disease requiring more frequent monitoring. Pockets of 5mm or deeper typically require a deep cleaning to control the infection.
Does deep cleaning actually work?
Yes — for early to moderate gum disease, scaling and root planing is highly effective. Studies show it reduces pocket depths by 0.5–2mm and significantly reduces the bacterial load that drives gum disease. It doesn't reverse bone loss that's already occurred, but it stops progression in most patients when followed up with periodontal maintenance cleanings every 3–4 months.
Frequently asked questions
How often do I need a deep cleaning? +
A deep cleaning is typically a one-time treatment (sometimes repeated in areas that don't respond). After a successful deep cleaning, you transition to periodontal maintenance (more thorough than regular cleanings) every 3–4 months. This is different from routine prophylaxis and is coded differently for insurance purposes.
Is a dental deep cleaning necessary, or is it upselling? +
Deep cleaning is genuinely necessary for documented gum disease — it's a medical procedure supported by decades of periodontal research. However, some dental offices do aggressively recommend it for borderline cases. If you're unsure, ask your hygienist to show you your pocket depth measurements. Pockets consistently at 4mm or less in a patient with healthy gum tissue typically don't require deep cleaning.
How long does deep cleaning recovery take? +
Gum soreness and sensitivity for 3–7 days is normal. Gum tissue may look slightly receded initially as swelling subsides — this is normal and not permanent damage. Avoid hard and crunchy foods for a few days. Rinsing with warm salt water accelerates healing.
