What is a deep cleaning?
A deep cleaning, also called scaling and root planing, is a procedure to remove tartar and bacteria from below your gumline. Unlike a regular cleaning that focuses on the visible tooth surface, a deep cleaning targets the area between your tooth and gum — a space that can deepen when gum disease is present.
Your dentist may recommend a deep cleaning if:
- Gum pocket measurements show depths greater than typical
- Tartar has built up below the gumline (visible on X-rays)
- You have signs of gum disease, such as bleeding, swelling, or persistent bad breath
Why does my dentist think I need one?
Gum disease starts when plaque (a sticky film of bacteria) hardens into tartar. If tartar forms below your gumline, a regular cleaning cannot reach it. Over time, bacteria in these pockets can damage the tissues that hold your tooth in place.
Asking your dentist to show you pocket-depth measurements and X-rays is a smart move. Understanding why they recommend a deep cleaning helps you make an informed decision. If you’re unsure, a second opinion from another dentist is always reasonable.
What happens during the appointment?
A deep cleaning usually takes place over one or more visits. Here’s what to expect:
Numbing: Your dentist or hygienist will apply a numbing medication to keep you comfortable during the procedure. This means you should feel pressure but not pain.
Scaling: Using specialized instruments, your dental professional will carefully remove tartar and buildup from below your gumline. You may hear scraping sounds and feel vibration — this is normal.
Root planing: After scaling, the root surface of your tooth is smoothed. This helps your gum reattach to the tooth and makes it harder for bacteria to colonize the area in the future.
Duration: A deep cleaning typically takes 30 minutes to an hour per section of your mouth, depending on how much buildup is present.
Recovery and aftercare
Most people can return to normal activities immediately after a deep cleaning. However, you may experience:
- Gum tenderness: Your gums may feel sore or tender for a few days. This is expected as they begin to heal.
- Tooth sensitivity: You might notice increased sensitivity to hot, cold, or pressure — usually temporary and improving over 1–2 weeks.
- Minor bleeding: Light bleeding when brushing is normal for a few days. Avoid aggressive brushing during healing.
Your dentist may recommend:
- Using a soft-bristled toothbrush
- Rinsing gently with warm salt water (ask your dentist for guidance)
- Avoiding very hot foods and drinks for a day or two
- Continuing good oral hygiene at home
If pain or sensitivity lasts longer than a week, or if you develop signs of infection (increased swelling, pus, fever), contact your dentist right away.
Ask good questions
Before your appointment, feel free to ask:
- “Can you show me my pocket measurements and explain why you recommend a deep cleaning?”
- “How many visits will this take?”
- “What should I expect during recovery?”
- “How will I know if the treatment is working?”
Your dentist should be happy to explain their reasoning and answer your concerns.

Frequently asked questions
How is a deep cleaning different from my regular cleaning?
A regular cleaning (prophylaxis) removes plaque and tartar from above your gumline and tooth surfaces you can see. A deep cleaning reaches below your gumline, where a regular cleaning cannot access. It removes tartar and bacteria that have built up in pockets between your tooth and gum, which is often the cause of gum disease.
Why would my dentist recommend a deep cleaning?
Your dentist may recommend a deep cleaning if measurements of your gum pockets show they are deeper than normal, or if X-rays reveal tartar below the gumline. These are signs of gum disease. A deep cleaning is meant to remove the buildup and help your gums heal. Ask your dentist to show you the pocket-depth measurements and explain why they believe a deep cleaning is right for you.
Is it normal to have sensitivity after a deep cleaning?
Some sensitivity or mild discomfort after a deep cleaning is common and usually temporary. Your gums may be tender for a few days. Over-the-counter pain relief may help — ask your pharmacist or dentist what's appropriate for you. Sensitivity to temperature may also occur for a short time as your gums heal. If sensitivity or pain persists beyond a week or worsens, contact your dentist.
