What scaling and root planing is

The name describes two procedures. Scaling removes plaque and calculus from the tooth and root, including deposits at the base of a pocket. Root planing smooths the root, so that the tissue can adapt against a clean surface rather than a rough one holding bacteria.

The work is done with ultrasonic instruments, which use vibration and water to break deposits loose, and hand instruments that let the operator feel when a root is clean. You will hear the ultrasonic instrument and feel water and pressure, but with the area numbed, nothing sharp.

The body then does its part. With the irritant gone, inflammation subsides, the swollen tissue shrinks and the gum tightens against the root. Depths usually reduce through that shrinkage and through some genuine reattachment. Scaling and root planing on its own does not generally rebuild lost bone, which is a separate question handled by regenerative or grafting procedures where they are appropriate.

Routine cleaning and deep cleaning compared

The two are often confused. They treat different conditions and are not interchangeable.

Consideration Routine cleaning Scaling and root planing
Who it is for Healthy gums or gingivitis, with attachment and bone intact. Periodontitis, with pockets and bone loss measured and recorded.
Anesthetic and visits Usually no anesthetic, and one appointment. Local anesthetic is normal, and a quadrant or half the mouth per visit.
What comes next The next routine visit, generally in six months. A re-evaluation four to six weeks later, then maintenance at a shorter interval.
How it is billed As a preventive cleaning. As a separate therapeutic procedure with its own code. Plans handle the two differently, so ask about coverage before treatment begins. See insurance and financing.

How a course of treatment proceeds

  1. Treatment by section

    One quadrant or half the mouth is numbed and treated, usually over about an hour. Dividing the work keeps the amount of anesthetic reasonable and allows enough time for each root surface.

  2. Local antimicrobials in selected sites

    A locally delivered antimicrobial is sometimes used in an isolated deep pocket after it has been cleaned. Where it is used, it works alongside thorough instrumentation rather than in place of it, and it is not needed in most straightforward cases.

  3. Home care in between

    Healing depends on plaque being disrupted daily at the gumline, so this affects the result as much as the appointments do. See brushing and flossing.

  4. Re-evaluation four to six weeks later

    The same sites are re-measured against the starting chart. Falling depths and fewer bleeding points mean the treatment worked. Sites that have not responded are identified so they can be addressed.

  5. Maintenance, or a referral

    Many people move to a three or four month maintenance interval. Where pockets stay deep despite thorough treatment and good home care, a periodontist is the next step.

What to expect in the first few days

Recovery is usually uneventful. Knowing what to expect makes the first week easier.

  • Numbness for a few hours. Take care not to bite your lip, cheek or tongue while it wears off.
  • Tenderness for a day or two. Over-the-counter pain relief taken as directed is sufficient for most people. Ask your pharmacist or physician if you are unsure what is suitable for you.
  • Cold sensitivity, often for a few weeks. With the swelling down and the deposits gone, more root surface is exposed. A sensitivity toothpaste usually helps.
  • Gums shrink, so teeth can look longer. The swollen tissue was maintaining a contour it should not have had. Spaces may open between teeth and food may collect in them. That is the true gum level becoming visible rather than new damage.
  • Some bleeding while brushing at first. It should decrease week by week. If it has not decreased by the re-evaluation, that is useful information and it helps direct the next step.
  • Keep brushing the treated area. Brush gently, but do not skip it. The tissue heals better when the area is cleaned every day.

What treatment can and cannot do

For many people who complete treatment and keep up with maintenance, it reduces pocket depths, stops the bleeding, and halts or greatly slows further attachment loss. The response varies from person to person and depends on your general health and on daily home care. Scaling and root planing on its own does not rebuild lost bone, it will not resolve every pocket, and the result is unlikely to last without follow-up care. Smoking and poorly controlled diabetes both make a good result harder to reach. Where deep sites remain, regenerative or surgical options can be discussed, usually with a periodontist.

Questions about deep cleaning

Why can this not all be done in one visit?

There is a practical limit to how much anesthetic is used at one sitting, and numbing a whole mouth would leave you unable to eat or speak comfortably for hours.

Do I need antibiotics as well?

Usually not. Periodontitis is driven by deposits attached to root surfaces, and medication does not remove deposits. A locally delivered antimicrobial in a deep pocket is sometimes useful. Systemic antibiotics are generally reserved for situations like an acute abscess, and any prescribing decision is made case by case.

What happens if I leave it untreated?

Periodontitis tends to progress in bursts rather than steadily, so nobody can give you a reliable timeline. The general direction is deeper pockets, more bone loss, teeth that loosen and drift, and in time extractions.

Will I have to have this done again?

Scaling and root planing is a course of treatment rather than a procedure repeated routinely. After it you move to maintenance. If specific sites break down later, those sites may need re-treating.
