SRP stands for scaling and root planing, a deep-cleaning dental procedure used to treat gum disease. It goes well beyond a standard cleaning: your dentist or hygienist works below the gumline to remove built-up plaque and tartar from the roots of your teeth, then smooths those roots so your gums can reattach. Most people are recommended SRP when the pockets between their gums and teeth measure 4 millimeters or deeper, a sign that gum disease has progressed past what a routine cleaning can address.
How SRP Differs From a Regular Cleaning
A standard dental cleaning, technically called a prophylaxis, is preventive care. The hygienist removes plaque, tartar, and stains from the visible surfaces of your teeth, and your dentist checks for cavities and other problems. Most people get this once or twice a year. It’s designed for mouths without active gum disease.
SRP is a treatment, not a preventive measure. It targets bacteria and deposits that have migrated beneath your gumline into the pockets around your tooth roots. Those pockets form when gum disease causes your gum tissue to pull away from your teeth. A regular cleaning doesn’t reach deep enough to address this, which is why SRP exists as a separate, more involved procedure.
What Happens During the Procedure
SRP has two distinct steps, often performed in the same visit. During scaling, the hygienist uses specialized instruments (sometimes ultrasonic, sometimes manual) to scrape plaque and hardened tartar from your teeth both above and below the gumline, all the way to the bottom of each pocket. This is the removal phase.
Root planing follows. Your tooth roots have a slightly rough surface that bacteria cling to easily. The hygienist smooths these root surfaces down, which makes it harder for plaque and tartar to reattach and gives your gum tissue a clean surface to heal against. Think of it as sanding down a rough piece of wood so paint can stick to it properly. In this case, the “paint” is your gum tissue reattaching to the tooth.
Depending on how many teeth are affected, your dentist may treat your whole mouth in one appointment or split it across two to four visits, tackling one section at a time.
Pain Management and What It Feels Like
Because the instruments go below the gumline and work directly on tooth roots, SRP can be uncomfortable without some form of numbing. Most dentists use a local anesthetic injection, the same type used for fillings. For patients who want to avoid needles, some offices offer a topical anesthetic gel applied directly into the periodontal pockets. This gel numbs the area within 30 seconds to 2 minutes. If it doesn’t provide enough relief, your dentist can switch to a traditional injection.
During the procedure itself, you’ll feel pressure and vibration, particularly if ultrasonic instruments are used. There may be occasional sharp sensations in areas where the pockets are deepest. The process takes longer than a standard cleaning, typically 45 minutes to an hour per section of the mouth.
Recovery and Aftercare
Most people feel back to normal within a week. The first day or two tend to be the worst, with gum soreness and sensitivity to cold or touch being the most common complaints. Over-the-counter pain relievers like ibuprofen or acetaminophen are usually enough to manage any discomfort.
For the rest of the day after your appointment, take it easy. Avoid strenuous exercise, alcohol, and foods that are spicy, very hot, very cold, acidic, or crunchy (chips, nuts, popcorn, hard bread). These can irritate healing gum tissue or get stuck in sensitive areas.
You should continue brushing and flossing as normal, just be gentler around the treated gums. Use a soft-bristle toothbrush. Rinsing with warm salt water two to three times a day for the first couple of days helps with healing. The right ratio is about a quarter teaspoon of salt in a full glass of warm water. Stronger solutions can actually increase irritation. If your dentist provides a fluoride toothpaste or rinse, using it consistently will help reduce tooth sensitivity faster.
How Well SRP Works
SRP is effective at reducing pocket depth, which is the primary measure of gum disease severity. For moderate pockets (4 to 6 millimeters), studies show an average reduction of about 1.5 millimeters. For deep pockets of 7 millimeters or more, the average reduction is closer to 2.6 millimeters. That may not sound dramatic, but even a millimeter or two can shift a pocket from the “disease is progressing” range into the “manageable with good hygiene” range.
Results are typically evaluated about six months after treatment. Not every tooth responds equally. Teeth that are harder to reach, like molars in the back of the mouth, sometimes show less improvement. If pockets remain deep after SRP, your dentist may recommend surgical options to access and clean the roots more thoroughly.
What Comes After: Periodontal Maintenance
Once you’ve had SRP, you don’t simply go back to twice-yearly regular cleanings. Instead, you’ll move to periodontal maintenance visits, which are more frequent and more thorough. For most patients, this means a cleaning every three months, though the interval can vary based on how well your gums respond.
These maintenance appointments look similar to a regular cleaning on the surface: tartar removal, polishing, a check for cavities and other problems. But the hygienist also measures your pocket depths at every visit, cleans deeper under the gumline than a standard prophylaxis would, and flushes any inflamed or infected pockets with antiseptic medication. The goal is to prevent gum disease from returning, because once you’ve had it, you’re at higher risk for recurrence. Skipping or spacing out these maintenance visits significantly increases the chance that pockets will deepen again and bone loss will continue.
Insurance and Cost Considerations
Dental insurance typically covers SRP under its periodontal benefits, but coverage varies widely. The procedure is billed per quadrant of the mouth (upper left, upper right, lower left, lower right), so costs depend on how many areas need treatment. Some plans limit how often you can have SRP or require documentation of pocket depths of 4 millimeters or more before approving the claim.
Periodontal maintenance visits after SRP are billed differently from regular cleanings, and some insurance plans cover fewer of them per year than the three or four your dentist may recommend. It’s worth checking your specific plan before treatment so you know what portion you’ll be responsible for. Many offices will verify this for you before scheduling.
