Scaling and Root Planing: What a Deep Cleaning Involves

Scaling and root planing is the standard non-surgical treatment for gum disease, and it's what most dentists mean by a "deep cleaning." It removes plaque and hardened tartar from below the gumline, then smooths the tooth roots so your gums can heal and fit snugly against the teeth again.

If you've just been told you need one, you probably have questions. At Peterborough Family Dental & Implant Center in Peterborough, NH, gum treatment is part of the everyday dental services we provide, and we'd rather you understand the plan than simply agree to it. This guide covers when a deep cleaning is needed, what it feels like, and what comes after.

What is scaling and root planing?

It's a two-part deep cleaning for gum disease. Scaling removes plaque and tartar from the tooth surfaces and from the pockets below the gumline. Root planing smooths the root surfaces so bacteria have a harder time reattaching and the gums can tighten back around the teeth.

Here's why it's needed. When plaque sits along the gumline, the gums get inflamed and start pulling away from the teeth, forming spaces called pockets. According to the ADA's MouthHealthy guide to deep cleaning, plaque trapped in those pockets can't be reached by brushing. Left alone, the infection can damage the bone that holds your teeth in place.

A deep cleaning goes after the source. By clearing out the pockets and smoothing the roots, it gives the gum tissue a clean surface to heal against. For many people with early to moderate gum disease, that's enough to bring the problem under control without surgery.

It's a common need. A national study in The Journal of the American Dental Association found that about 42% of U.S. adults aged 30 and older have periodontitis, the stage of gum disease that usually calls for this treatment. About 8% have the severe form.

How do you know if you need a deep cleaning?

You need a deep cleaning when your exam shows periodontitis, not just gingivitis. The main clue is pocket depth. Healthy gum pockets are usually 1 to 3 millimeters deep, while deeper pockets, especially with bleeding, tartar below the gumline, or bone loss on X-rays, point to deeper treatment.

Gum disease often causes no discomfort until it's advanced, so the measurements matter more than how your mouth feels. Still, these signs are worth paying attention to:

• Gums that bleed when you brush or floss
• Red, swollen, or tender gums
• Bad breath that doesn't go away with brushing
• Gums that look like they're pulling away from the teeth
• Teeth that feel loose or have shifted

If several of those sound familiar, our guide to gum disease warning signs explains what each one can mean. And if your main concern is persistent bad breath, our article on chronic bad breath causes is worth a read, because gum pockets are a common source.

At your visit, the hygienist gently measures around each tooth with a thin probe. Those numbers, along with X-rays, tell your dentist whether a routine cleaning is enough or whether a deep cleaning is the right next step.

What's the difference between gingivitis and periodontitis?

Gingivitis is the early, reversible stage of gum disease, limited to the gum tissue. Periodontitis is the advanced stage, where the infection has reached the bone that supports your teeth. Gingivitis usually needs a thorough cleaning and better home care, while periodontitis typically calls for a deep cleaning.

Periodontitis is also staged by severity. Early to moderate stages are usually managed with a deep cleaning and maintenance. Advanced stages with significant bone loss often need input from a periodontist, the dental specialist for gums.

That's why catching gum disease early matters so much. At the gingivitis stage, a few weeks of better habits can make a real difference. Once bone is involved, the goal shifts from reversing the problem to protecting what's left.

What happens during the procedure, step by step?

A deep cleaning is usually done in two or more visits, treating one area of the mouth at a time. The area is numbed with local anesthetic, the pockets are cleaned with ultrasonic and hand instruments, and the roots are smoothed. A follow-up visit a few weeks later checks how your gums responded.

1. Numbing. Topical gel goes on first, then local anesthetic so you feel pressure rather than sharp sensations.
2. Scaling. An ultrasonic scaler breaks up tartar with vibration and water, and hand instruments clean the deeper spots.
3. Root planing. The root surfaces are smoothed so the gums can reattach more easily.
4. Rinsing and checking. The pockets are flushed, and your dentist may place medication in deeper areas or prescribe a rinse.
5. Re-evaluation. A few weeks later, your pockets are measured again to see how much they've tightened.

Splitting the work across visits keeps each appointment manageable and lets the numbing cover just the area being treated. If you're anxious, Peterborough Family Dental also offers nitrous oxide and oral sedation, and our team will talk through those options before you book.

How is this different from your usual cleaning? A routine cleaning works above and just below the gumline on healthy gums. Our guide on what happens during a dental cleaning covers the routine version step by step.

What does recovery feel like?

Most people feel some tenderness for a day or two after a deep cleaning, and the ADA notes that teeth can stay sensitive to temperature for up to a week. Your gums may also look a bit swollen and bleed slightly when you brush at first. These effects usually fade as the gums heal.

A few things help in the first days:

• Take an over-the-counter reliever if your dentist says it's fine for you.
• Stick to softer foods on the treated side until the numbness wears off.
• Use a toothpaste for sensitive teeth if cold drinks bother you.
• Rinse gently with warm salt water if your dentist recommends it.

Some sensitivity can actually be a sign of progress. As inflammation goes down, the gums tighten, and a little more of the root surface may be exposed for a while. If sensitivity gets worse instead of better, or you notice swelling or a bad taste, call the office.

Most people go back to work or school the same day. The numbness usually wears off within a few hours, so plan meals around that and avoid hot drinks until you can feel your lips again. If you're treating both sides on separate days, you'll usually have a week or two between visits, which gives the first side time to settle before the second.

How should you care for your gums afterward?

Daily home care is what keeps a deep cleaning working. Brush twice a day with a soft brush, clean between your teeth every day, avoid tobacco, and keep every follow-up visit. Without that, plaque refills the pockets and gum disease can return.

Your hygienist will show you the technique that fits your mouth. For many people, that means an electric brush for better gumline cleaning and floss, interdental brushes, or a water flosser for the spaces between teeth. Our comparison of water flossers vs floss can help you choose.

Smoking deserves its own mention. It raises the risk of gum disease and slows healing, and it can hide early warning signs like bleeding. If you smoke or vape, cutting back is one of the most helpful things you can do for your gums.

Health conditions matter too. Poorly controlled diabetes makes gum disease harder to manage, and research has linked untreated gum disease with other conditions like heart disease. Treating your gums is good for more than your mouth.

Can gum disease come back after a deep cleaning?

Yes, it can, which is why follow-up care matters so much. Gingivitis can be fully reversed, but periodontitis is managed rather than erased. The bone lost to gum disease doesn't grow back, so the goal is to stop further damage and keep the pockets healthy over time.

After active treatment, most patients move to periodontal maintenance visits every three to four months instead of standard six-month cleanings. These visits include updated pocket measurements and targeted cleaning of the areas that were affected.

Sometimes pockets don't tighten enough after the first round. The American Academy of Periodontology notes that non-surgical treatment has limits, and some people need further care from a periodontist. At our office, more advanced cases are coordinated with a specialist when that's the right move.

Gum recession is a related concern. If your gums have pulled back, our article on receding gums treatment explains your options.

Is scaling and root planing covered by insurance?

Most dental insurance plans cover scaling and root planing as a periodontal benefit, often at a different level than routine cleanings. Our team verifies your benefits for free before treatment and gives you a written estimate, so you'll know your share before anything starts.

Without insurance, our VIP Membership Plan includes a Periodontal plan for patients with gum disease. It covers three to four maintenance visits, two exams, routine X-rays, and an oral cancer screening each year, plus member savings on most treatment.

Some patients also spread costs with CareCredit or use HSA or FSA funds. Our guide to dental financing options explains how to combine them, step by step, so the amount you finance stays small.

Whatever the cost question, waiting rarely helps. Bone lost to gum disease is permanent, and treating it early is almost always simpler than treating it late. Learn more on our gum disease treatment page.
