Periodontal treatment is any dental procedure designed to treat gum disease, from deep cleanings that remove bacteria below the gumline to surgical procedures that rebuild lost bone. The specific treatment you need depends on how far the disease has progressed, measured by the depth of the pockets between your gums and teeth. Healthy gums have pockets of 3 millimeters or less, while pockets of 5 millimeters or deeper signal active disease that’s damaging the bone supporting your teeth.
How Pocket Depth Guides Your Treatment
Your dentist or periodontist measures the space between each tooth and the surrounding gum tissue using a thin probe. Readings of 3 mm or less are consistent with healthy gums. A measurement of 4 mm sits in a gray zone between health and disease. Once pockets reach 5 mm or deeper, there’s a real risk of progressive bone and tissue loss, and treatment becomes necessary to stop the damage from advancing.
These measurements determine which category of treatment makes sense for you. Shallow to moderate pockets can typically be managed without surgery. Deeper pockets, or cases where bone has already been lost, often require a surgical approach. Your treatment plan may combine several of the procedures described below.
Scaling and Root Planing: The First Line of Treatment
The most common periodontal treatment is scaling and root planing, sometimes called a “deep cleaning.” It goes well beyond a standard dental cleaning, which only removes tartar from above the gumline. During scaling and root planing, your provider numbs the gums with local anesthesia, then uses hand instruments or ultrasonic tools to remove plaque and hardened tartar from both above and below the gumline, all the way down to where the root, gum, and bone meet.
The second step, root planing, smooths the root surfaces of your teeth. Rough or irregular root surfaces give bacteria a foothold to reattach and start forming new deposits. Smoothing those surfaces makes it harder for plaque and tartar to build back up, and it encourages your gum tissue to reattach more snugly to the tooth. In some cases, your provider will also place an antibiotic directly into the pockets or prescribe an oral antibiotic to help control infection after the procedure.
For early to moderate gum disease, this non-surgical approach is often enough to bring the condition under control. But when pockets remain deep or bone loss continues despite thorough cleaning, surgical options come into play.
Surgical Procedures for Advanced Disease
When gum disease is too advanced for deep cleaning alone, a periodontist may recommend pocket reduction surgery (also called osseous surgery). The goal is straightforward: reduce the depth of the pockets around your teeth so bacteria can no longer hide in them. During this procedure, the periodontist makes small incisions in the gum tissue to access the tooth roots and underlying bone directly. They then reshape the bone to eliminate the deep pockets and areas of damage before stitching the tissue back into place.
Periodontists reserve osseous surgery for moderate to severe gum disease. It’s not a first option, but when non-surgical treatment has reached its limits, this procedure can stabilize teeth that might otherwise be lost.
Regenerative Treatments
In cases where gum disease has eaten away at the bone, regenerative procedures aim to rebuild what’s been lost. Bone grafting places material into the damaged area to encourage new bone growth. Guided tissue regeneration takes this a step further by using a thin membrane, either one that dissolves on its own or one that’s removed later, to control which type of cells grow into the healing site. Soft tissue cells grow much faster than bone cells, and without a barrier, they would fill the space before bone has a chance to regenerate. The membrane holds them back, giving the slower-growing bone cells the time and space to rebuild.
Laser-Assisted Surgery
A newer alternative to traditional scalpel-based surgery uses a specialized dental laser to remove diseased tissue and promote reattachment of healthy gum tissue to the tooth root. Because the laser is less traumatic to the surrounding tissue than a scalpel, patients generally experience less swelling and bleeding during recovery. Most people who undergo laser periodontal surgery can return to normal activities within a day or two. Providers who perform this procedure must complete specialized certification training, so it’s not available in every dental office.
Do Localized Antibiotics Help?
You may hear about antibiotic gels or microspheres placed directly into periodontal pockets alongside scaling and root planing. These products release medication slowly over days or weeks to fight bacteria at the site of infection. Studies have found that repeated applications of these localized antibiotics can reduce pocket depth by roughly 0.3 to 3.8 mm and produce some gains in tissue attachment. However, the overall evidence for adding these products on top of thorough scaling and root planing remains weak. A systematic review of the available studies found that the repeated use of locally delivered antibiotics lacked clear statistical and clinical significance, with most studies carrying a high risk of bias. They may offer a modest benefit in specific situations, but they’re not a substitute for the mechanical cleaning itself.
What Recovery Feels Like
After non-surgical treatment like scaling and root planing, early to moderate cases typically heal within two to three weeks. Severe cases that require surgical intervention may take five to eight weeks. Tenderness and slight bleeding in the first few days are normal. Sensitivity to hot and cold foods is also common but usually fades within one to two weeks as the tissue heals.
During recovery, eating a diet rich in vitamins C and D supports the healing process. Vitamin C fuels collagen production, which is critical for rebuilding healthy connective tissue in the gums. Citrus fruits, bell peppers, and leafy greens are good sources. Vitamin D helps your body absorb calcium for bone health, so fortified dairy products or a supplement can be helpful if your intake is low.
Periodontal Maintenance vs. Regular Cleanings
Once you’ve been treated for gum disease, you don’t go back to standard twice-a-year cleanings. Instead, you move to periodontal maintenance, which is a fundamentally different appointment. A regular cleaning (prophylaxis) removes tartar from above the gumline and is meant for people with healthy gums. Periodontal maintenance involves scaling and root planing along the entire length of each tooth, down to where the root and bone meet. Your hygienist will also measure the depth of every pocket at each visit and may irrigate the pockets with antiseptic medication if inflammation or infection is present.
These maintenance appointments are typically scheduled every three to four months rather than every six months. The shorter interval is important because the bacteria responsible for gum disease can repopulate pockets relatively quickly, and more frequent monitoring catches any progression before it causes further damage.
Long-Term Outlook With Treatment
Periodontal treatment is effective at preserving teeth. In one study tracking 25 patients over an average of nearly 11 years, only 22 teeth out of 656 were lost during the entire follow-up period. Interestingly, the study found no significant difference in tooth loss between patients who attended maintenance visits two to four times a year and those who came just once a year, suggesting that even modest ongoing care provides meaningful protection once active disease has been treated.
The key takeaway is that periodontal treatment isn’t a one-time fix. It’s the beginning of a long-term management strategy. The initial procedures stop the active infection and repair damage where possible. Maintenance appointments keep the disease from returning. Together, they give you the best chance of keeping your natural teeth for decades.
