What is the difference between a regular and a deep cleaning?
A regular cleaning keeps healthy gums healthy. A deep cleaning treats gum disease. Cleveland Clinic calls a routine cleaning (prophylaxis) the most common type, meant for people with healthy teeth and gums. A deep cleaning, which dentists call scaling and root planing, is a special cleaning for people with gum disease. It reaches under the gums and around the tooth roots.
Cleveland Clinic describes a deep cleaning as sort of like a regular cleaning, except that it reaches deeper beneath your gums. The dentist numbs your gums first. Read more about a routine cleaning and scaling and root planing in our glossary.
How do the two cleanings compare?
| Regular cleaning | Deep cleaning | |
|---|---|---|
| Who it is for | People with healthy teeth and gums | People with gum disease |
| What it removes | Plaque and tartar from the tooth surfaces | Plaque and tartar above and below the gums, plus root smoothing |
| Comfort | Scaling should not hurt | Local anesthetic numbs the gums first |
| Time | 30 to 60 minutes | One to two hours, sometimes split into two visits |
| After | Sensitive teeth or sore gums for a few days | Soreness for a day or two, sensitivity up to a week |
| How often | About every six months for most people | Ideally once, then regular cleanings and checkups |
The times and recovery notes come from Cleveland Clinic and MouthHealthy. Your visit may differ.
Why do some people need a deep cleaning?
The reason is gum disease. Plaque is a sticky film of bacteria that is always forming on your teeth. MouthHealthy says that if teeth are not cleaned well, the bacteria in plaque can inflame your gums. Then the gums pull away from the teeth and form spaces called pockets. Plaque gets trapped in these pockets, and regular brushing cannot remove it.
NIDCR explains that pockets in a healthy mouth are usually between 1 and 3 millimeters deep, and deeper pockets can be a sign of periodontal disease. MouthHealthy adds that if gum disease is caught early and has not damaged the structures below the gumline, a professional cleaning should do. If the pockets are too deep, scaling and root planing may be needed.
Our gum disease guide explains the stages, and our post on gingivitis vs periodontitis covers the difference in plain words.
What happens during a deep cleaning?
Cleveland Clinic lists these steps:
- The dentist or hygienist numbs your gums with local anesthesia.
- They scale your teeth. This removes plaque and tartar above and below the gums.
- They plane your tooth roots. This smooths the roots so plaque and tartar have a harder time sticking.
- They may place antibiotics around the roots or prescribe antibiotics to take afterward.
Hand scalers or ultrasonic tools do the work. A deep cleaning takes one to two hours. Your dentist might do it all in one visit, or clean half your teeth at one appointment and half at the next, depending on your needs and your insurance plan.
MouthHealthy says the dentist will schedule another visit to see how your gums have healed and to measure pocket depth again. If the pockets have grown deeper, more treatment may be needed.
Does a deep cleaning work?
MouthHealthy cites a July 2015 study in the Journal of the American Dental Association, which finds that scaling and root planing benefits patients with chronic periodontitis, gum disease that has gone past gingivitis. Cleveland Clinic says it is usually the first line of treatment for mild to moderate gum disease and that it can help with sore, bleeding gums. Results differ from person to person, and your dentist will talk with you about what to expect.
What is recovery like?
Most people go back to normal routines the same day, per Cleveland Clinic. It is a nonsurgical treatment, so there are no incisions or stitches. You can eat and drink what you like as long as it does not hurt.
MouthHealthy says you may have pain for a day or two and tooth sensitivity for up to a week, and your gums may be swollen, tender, and bleed. Cleveland Clinic lists other possible effects: some bleeding, gums that shrink back as swelling goes down, teeth that feel a little loose for a short time, and sensitivity to heat and cold that should go away in a month or two.
Call your dentist if you have bleeding that does not stop, pain that does not get better with medication, or severe swelling.
Do you need a deep cleaning?
You cannot tell from the mirror. Gum disease usually does not hurt, and MouthHealthy says you may not know you have it. Warning signs include gums that bleed easily, red, swollen, or tender gums, and gums that pull away from the teeth. Only a dental exam with measurements and X-rays can show whether you need a deep cleaning or a regular one. If you are unsure, start with a checkup and ask. Our post on how often to get your teeth cleaned explains the usual schedule.
The office gives each patient their own estimate for treatment, and the cost depends on your plan and needs.
What should you ask before a deep cleaning?
- What did my measurements and X-rays show?
- Will you do it in one visit or two?
- Will I be numb, and for how long?
- What should I eat and avoid afterward?
- When will you check my gums again?
- How should I change my brushing and flossing?
Written answers help you follow the plan at home. Bring a friend or family member if that helps you remember them.

Frequently asked questions
How do I know if I need a deep cleaning?
Your dentist or hygienist measures the spaces between your gums and teeth and takes X-rays. NIDCR says pockets in a healthy mouth are usually 1 to 3 millimeters, and deeper pockets can signal gum disease. MouthHealthy says deep cleaning may be needed when pockets are too deep. Only an exam can tell.
Is a deep cleaning painful?
Cleveland Clinic says the dentist numbs your gums first. MouthHealthy says you may have pain for a day or two and tooth sensitivity for up to a week afterward, and your gums may be swollen, tender, and bleed. Tell the team if anything hurts during the visit so they can add numbing.
How long does a deep cleaning take?
Cleveland Clinic says a deep cleaning takes one to two hours. Your dentist might do it in one visit, or clean half your teeth at one appointment and half at another. Ask the office how your own plan is set up.
Will I need a deep cleaning more than once?
Cleveland Clinic says that ideally you will need scaling and root planing only once, and that regular cleanings and good home care help keep gum health on track. Many people with gum disease then see the dentist more often. Your dentist sets that schedule.
