About this procedure
A deep cleaning — clinically called scaling and root planing (SRP) — is a periodontal treatment for patients with early to moderate gum disease. The hygienist or periodontist removes hardened plaque and tartar from below the gumline and smooths the root surfaces so the gums can reattach to the teeth. Deep cleaning is different from a routine prophylaxis (the regular cleaning you get every 6 months). It's billed per quadrant — the mouth is divided into four sections, and most patients with gum disease need treatment in two or four quadrants.
Depending on severity, deep cleaning is typically performed over 1–2 visits, often with local anesthesia. After the deep cleaning, patients usually move to ongoing periodontal maintenance (a separate procedure billed at a higher rate than a prophylaxis) every 3–4 months.

Quote checker
What should your quote include?
Different offices bundle costs differently. Here's what a complete quote typically covers — and what's often left out.
Usually included in the quoted price
- Scaling and root planing per quadrant
- Local anesthesia
- Post-procedure evaluation appointment
- Antibiotic placement or irrigation if used
Often billed separately — ask before you agree
- Confirm whether all four quadrants are included or each is billed separately
Health stakes
What happens if you delay treatment?
Restorative procedures are usually recommended once a tooth has lost too much structure to remain stable on its own. Waiting rarely makes the situation simpler.
- Gum disease advances from gingivitis to irreversible periodontitis
- Permanent bone and gum loss around teeth occurs
- Teeth become loose and may require extraction
- Systemic inflammation linked to heart disease, diabetes, and pregnancy complications
- Full-mouth reconstruction may become necessary

Common questions
Frequently asked questions
What's the difference between a regular cleaning and a deep cleaning?
A regular cleaning (prophylaxis) is preventive care for healthy or near-healthy gums and removes plaque/tartar from above the gumline. A deep cleaning is a periodontal treatment for active gum disease, removing buildup from below the gumline and smoothing the roots. They are billed at very different rates and require different amounts of time.
Does insurance cover deep cleanings?
Most PPO plans cover scaling and root planing at 50–80% after the deductible, when periodontal disease is documented (pocket depths, bone loss on x-rays). Some plans require pre-authorization.
Why does my dentist suddenly say I need a deep cleaning?
Gum disease can develop without obvious symptoms — bleeding gums, mild redness, and bad breath are common but easy to dismiss. If your dentist sees deeper pockets or bone loss on x-rays, a deep cleaning is the standard treatment. If you're surprised by the recommendation, a second opinion is reasonable, especially before committing.
