What Is Root Planing and Why Do You Need It?
If your dentist recommended root planing (also called deep cleaning or scaling and root planing), you have gum disease that's progressed beyond simple gingivitis. Root planing is the treatment that cleans the root surfaces of your teeth below your gum line where your toothbrush can't reach. This isn't the same as a regular cleaning. Root planing is a therapeutic procedure that removes bacteria, infection, and contaminated material from your tooth roots to allow your gums to heal.
When you have gum disease, bacteria and tartar accumulate below your gum line in pockets between your teeth and gums. Your toothbrush can't reach these areas. The bacteria produce toxins that destroy your gum tissue, periodontal ligament, and bone. Root planing removes this infected material from your root surfaces and smooths them to help your gums reattach and heal.
What Happens During Root Planing
Your dentist or hygienist uses special instruments to clean below your gum line. They work methodically on different sections of your mouth, typically treating one quadrant (one quarter of your mouth) per appointment. This takes time—usually 45-90 minutes per quadrant—because thorough cleaning requires careful attention to every tooth surface.
Your provider uses either hand instruments (called curettes) or ultrasonic instruments (which vibrate at high frequency), or usually a combination of both. The hand instruments give tactile feedback so your provider knows when the surface is clean and smooth. The ultrasonic instruments are particularly good at breaking up heavy tartar and reaching deep areas. Once the major cleaning is done, your provider uses hand instruments to achieve a smooth surface that bacteria find harder to stick to.
Why Smoothing Your Roots Matters
The reason your dentist smooths your roots is more than just cosmetic. A rough root surface, covered with tartar and bacterial biofilm, provides bacteria a place to hide and multiply. When your roots are smooth, bacteria can't establish colonies as easily. This helps your gums heal and reduces the risk that bacteria will return and cause problems again.
The diseased outer layer of your root actually contains bacterial toxins embedded in it. When your dentist removes this layer, they're removing not just bacteria but also the poisons those bacteria produce. Exposing the clean layer underneath allows your body's healing cells to approach your tooth root and begin repair. Your gums literally grow back and reattach to your tooth through this healing process.
What to Expect During and After Treatment
During treatment, you'll feel pressure and hear the vibration of the instruments. If you're numb (which you should be), you shouldn't feel sharp pain—just pressure and vibration sensations. Some pressure or discomfort is normal, and you should tell your dentist if you're experiencing pain so they can numb you more.

After the anesthesia wears off, you'll likely feel some soreness and sensitivity. Your gums might be slightly swollen and tender for a few days. Over-the-counter pain medication and a soft toothbrush help. Avoid very hot foods and drinks for the first few days, and be gentle when brushing around the treated areas. Most soreness goes away within a week.
How Your Gums Heal After Root Planing
Your gums heal in stages. In the first few days, your body removes remaining debris and inflammation begins to resolve. Over the next week, new healing cells arrive and begin repairing tissue. Your gums should start reattaching to your teeth. By about 6 weeks, the initial healing is mostly complete, and your dentist will measure your gum pockets again to see how much improvement occurred.
The deepest, most complete healing takes longer—up to several months—as your body rebuilds lost bone and periodontal ligament. That's why your dentist wants to see you for follow-up visits and maintain good long-term care.
Using Both Hand and Ultrasonic Tools
Modern root planing usually combines hand and ultrasonic instruments because they work best together. Ultrasonic instruments quickly break apart heavy tartar, which is efficient. Hand instruments then allow your provider to confirm the surface is smooth and clean by feel, which is more accurate than relying on visualization alone. This combination approach gives you the speed advantage of ultrasonic cleaning with the precision verification of hand instruments.
What Happens if You Don't Keep Up with Maintenance
Here's the most important part: root planing works only if you maintain excellent oral hygiene afterward and keep up with professional maintenance visits. Studies show that if you have root planing but then don't floss, don't brush well, and skip your follow-up appointments, your gum pockets return to their diseased state within 2-3 months. The bacteria come back, and you're back where you started.
If you do maintain good home care (brushing twice daily, flossing daily, and visiting your dentist every 3-4 months), the improvements from root planing last. You keep your teeth, your gums stay healthier, and you avoid more serious problems like bone loss and tooth loss. For more on this topic, see our guide on Periodontal Maintenance Protocols.
Why Multiple Appointments Are Necessary
Root planing usually takes 2-4 appointments because doing it thoroughly takes time. Trying to treat your entire mouth in one long appointment often results in incomplete treatment because your provider gets fatigued and treatment quality suffers. Treating one quadrant (quarter of your mouth) at a time allows adequate time, good anesthesia, and thorough work. Your dentist schedules these appointments a week or two apart to allow some healing between treatments.
Following Up After Root Planing
Your dentist will schedule a follow-up visit 6-8 weeks after completing root planing to check how your gums are healing. They'll measure your pocket depths again—they should be noticeably shallower if treatment worked. If certain pockets are still deep or still bleeding, your dentist might discuss additional treatment options.
Keeping Your Results
After root planing, your gum disease is treated but not cured. Periodontitis is chronic—meaning it can return if you don't maintain good care. This is why your dentist will likely recommend maintenance visits more frequently than standard cleanings—typically every 3 months instead of every 6 months. These maintenance visits include gentle cleaning and frequent monitoring to catch any problem areas early.
Conclusion
Root planing is a crucial treatment for gum disease that removes the bacteria and toxins causing your gums to fail. By smoothing your root surfaces, your dentist allows your gums and bone to heal and reattach. The success of root planing depends equally on what your dentist does and what you do afterward through daily oral hygiene and regular maintenance visits. Understanding that this treatment requires ongoing commitment helps you appreciate its importance and be motivated to maintain the results.
> Key Takeaway: Root planing removes bacteria and toxins from below your gum line and smoothes root surfaces to allow healing, but success depends on your daily brushing/flossing and regular maintenance visits to prevent disease from returning.
