A periodontal cleaning, formally called scaling and root planing, is a deeper version of a standard dental cleaning designed to treat gum disease. While a regular cleaning focuses on the visible surfaces of your teeth and just below the gumline, a periodontal cleaning goes further, removing buildup from deep pockets that have formed between your gums and tooth roots. It’s one of the most common non-surgical treatments for periodontitis.
How It Differs From a Regular Cleaning
A standard prophylaxis (the cleaning most people get twice a year) removes plaque and tartar from the surfaces of your teeth and slightly below the gumline. It’s preventive maintenance for healthy gums. A periodontal cleaning targets a different problem entirely: bacteria and hardened deposits that have migrated deep beneath the gums into pockets around the tooth roots.
Your dentist or hygienist determines which type you need by measuring the space between your gums and teeth with a small probe. Healthy gums sit snugly against the tooth, creating a shallow gap of 1 to 3 millimeters. When gum disease is present, that gap deepens into what’s called a periodontal pocket. Measurements greater than 3 millimeters signal a problem, and once pockets reach 4 or 5 millimeters or more, a standard cleaning can’t reach the buildup. That’s when a periodontal cleaning becomes necessary.
What Happens During the Procedure
The procedure has two parts, which is where the name “scaling and root planing” comes from. First, your provider scales the teeth, meaning they remove plaque and tartar from both above and below the gumline, reaching into those deeper pockets. Then they plane the tooth roots, smoothing rough spots on the root surfaces. This smoothing step matters because bacteria cling to rough surfaces, and a smoother root gives your gums a better chance of reattaching tightly to the tooth.
Your provider will use either hand instruments (thin metal scalers) or ultrasonic tools that vibrate rapidly to break up hardened deposits. Many offices use a combination of both. The procedure is typically done under local anesthesia, so your gums are numbed before any work begins. Depending on how extensive the gum disease is, your dentist may treat your entire mouth in one visit or split it into two or more appointments, working on one section at a time. In some cases, your provider may also place antibiotics around the tooth roots or prescribe oral antibiotics to help control bacteria afterward.
What Recovery Feels Like
Some soreness, swelling, and bleeding are normal in the first few days. Your teeth will likely feel more sensitive to hot, cold, and sweet foods and drinks. This sensitivity is common and typically improves within one to two weeks. Over the following two to four weeks, your gums continue healing and gradually reattach to the teeth, and sensitivity should diminish significantly.
During recovery, a few adjustments help things heal faster:
- Eat soft foods for the first couple of days. Yogurt, mashed potatoes, scrambled eggs, and smoothies are good options. Avoid hard, crunchy, or sticky foods until your gums feel more comfortable.
- Brush gently with a soft-bristled toothbrush, especially near the gumline.
- Floss carefully to avoid irritating healing tissue.
- Avoid smoking, which slows healing and raises the risk of gum disease coming back.
Your provider may also prescribe an antimicrobial mouth rinse to keep bacteria in check while your gums recover. Persistent or severe pain, heavy bleeding, or swelling that doesn’t improve after a few days is worth a call to your dentist.
Potential Side Effects
The most common side effect is temporary gum tenderness and tooth sensitivity, which resolve on their own. In some cases, particularly when there’s significant tartar buildup, the cleaning can cause minor gum recession. This happens because swollen, inflamed gums shrink back to a healthier size once the infection and buildup are cleared. It can look like your teeth have gotten longer. While this is a normal part of the healing process, it can expose portions of the tooth root, which contributes to that post-procedure sensitivity.
Aggressive or overly forceful scaling can occasionally cause abrasions to the gum tissue. Ultrasonic instruments generate heat, which needs to be controlled with a water spray to avoid thermal irritation. These risks are low with an experienced provider but worth understanding before you go in.
What Happens After: Maintenance Schedule
A periodontal cleaning isn’t a one-time fix. Gum disease is a chronic condition, and once you’ve had it, you’re at higher risk for it returning. People with healthy gums typically need a standard cleaning every six months. After scaling and root planing, the recommended schedule shifts to periodontal maintenance visits every three to four months. These maintenance cleanings are more thorough than a standard prophylaxis and focus on monitoring pocket depths, checking for signs of disease progression, and cleaning areas that are harder to maintain at home.
Over time, if your gum health stabilizes, your dentist may adjust the frequency. But skipping or stretching out these appointments gives bacteria a chance to recolonize those deeper pockets, potentially undoing the progress made by the initial deep cleaning.
Cost and Insurance
Scaling and root planing is billed by quadrant (your mouth is divided into four sections). The cost typically ranges from $185 to $444 per quadrant, with a national average around $242. If all four quadrants need treatment, you’re looking at roughly $740 to $1,776 for the full mouth. Most dental insurance plans cover at least a portion of the cost when gum disease is documented, since it’s considered a medically necessary treatment rather than an elective one. Your out-of-pocket expense depends on your plan’s coverage and whether you’ve met your annual maximum.
