Root planing is a dental procedure that smooths the surfaces of your tooth roots beneath the gumline, removing bacteria, toxins, and hardened deposits that cause gum disease. It’s typically paired with scaling (which cleans above and just below the gumline) and together they’re often called a “deep cleaning.” If your dentist has recommended root planing, it means gum disease has progressed beyond what a standard cleaning can address.
How Root Planing Differs From Regular Cleaning
A standard dental cleaning focuses on removing plaque and tartar from the visible surfaces of your teeth and slightly below the gumline. Root planing goes deeper. The procedure targets the root surfaces of your teeth, where bacteria and their toxins become embedded in the outer layer of the root (called cementum). By smoothing these root surfaces, the procedure creates a clean foundation that makes it harder for bacteria to reattach and allows your gum tissue to heal and tighten back against the tooth.
The distinction matters biologically. Rough, contaminated root surfaces act like Velcro for bacteria. Smoothing them doesn’t mean stripping the root bare. Preserving a thin layer of the root’s outer surface is actually necessary for the tissue that connects your gum to your tooth to regenerate. The goal is removing just enough contaminated material to eliminate infection while keeping the foundation for healing intact.
When Root Planing Is Recommended
Your dentist measures the depth of the space between your gums and teeth using a small probe. Healthy gums typically have pocket depths of 1 to 3 millimeters. When pockets deepen beyond about 3 mm, it signals that gum tissue is pulling away from the tooth, creating space where bacteria thrive and standard brushing can’t reach.
Root planing is generally the preferred treatment for pocket depths in the 4 to 6 mm range. In this zone, it outperforms surgical options at helping gums reattach to the tooth. For pockets deeper than 6 mm, periodontal surgery tends to produce better results overall. Many patients with moderate gum disease never need surgery at all. The American Academy of Periodontology notes that a significant number of patients require no additional treatment beyond scaling and root planing, though most will need ongoing maintenance visits to keep things stable.
What Happens During the Procedure
Root planing is done with local anesthesia, so your gums and teeth are numbed before any work begins. A topical numbing gel is often applied first to minimize the discomfort of the injection itself. Once you’re numb, you’ll feel pressure but not pain.
Your dentist or hygienist uses two main types of instruments. Hand instruments called curettes are thin, curved tools designed to reach beneath the gumline and scrape contaminated material from root surfaces. Ultrasonic instruments vibrate at high frequencies to break up hardened deposits and flush debris from pockets with a stream of water. Ultrasonic tools are particularly useful for reaching difficult areas like the spaces where roots of multi-rooted teeth divide, and for cleaning deeper pockets without requiring as much physical force.
The procedure is often split into two or more visits, with each appointment focusing on one section of your mouth. This keeps the numbing manageable and gives your provider time to be thorough. Each session typically takes 45 minutes to an hour.
Recovery and What to Expect Afterward
Most people feel back to normal within a week. In the first day or two, you can expect some gum soreness and sensitivity to cold or touch, which usually resolves quickly. Using a fluoride toothpaste or a prescribed fluoride rinse helps reduce sensitivity within a few days.
For the first one to two weeks after treatment:
- Brush gently but thoroughly two to three times daily, using either a manual or electric toothbrush along with floss
- Rinse with warm salt water (a quarter teaspoon of salt dissolved in one cup of warm water) as needed to soothe your gums
- Use a prescribed antimicrobial rinse if your dentist provides one, typically twice daily for 30 seconds, to reduce inflammation and bleeding
Your gums may bleed slightly when you brush during the first few days. This is normal and will improve as the tissue heals. Avoiding very hot, cold, or spicy foods during the first couple of days can make recovery more comfortable.
Why Maintenance Visits Matter
Root planing isn’t a one-and-done fix. Gum disease is a chronic condition, and the bacteria that caused it will attempt to re-establish themselves. After active treatment, most patients need maintenance cleanings every three to four months rather than the standard six-month schedule. These more frequent visits allow your dental team to monitor pocket depths, clean areas that are hard to reach at home, and catch any signs of recurrence early.
The interval between maintenance visits depends on how well your gums respond to the initial treatment and how effectively you manage daily home care. Some patients eventually return to a six-month schedule, while others benefit from staying on a three-to-four-month cycle long term. Consistent daily brushing and flossing remain the most important factor in whether the results of root planing last.
