Periodontal disease can be managed and controlled, but whether it can be fully eliminated depends on how far it has progressed. In its earliest stage, called gingivitis, gum disease is completely reversible with proper care. Once it advances to periodontitis, where infection has spread to the bone and ligaments supporting your teeth, the damage is permanent. The goal shifts from curing the disease to stopping its progression, restoring as much tissue as possible, and keeping it from getting worse.
Gingivitis vs. Periodontitis: What Can Be Reversed
Gingivitis is inflammation that stays at the surface of your gums. There’s no bone involvement, and with consistent brushing, flossing, and a professional cleaning, it heals completely. Most adults experience gingivitis at some point, and many don’t realize it because the symptoms (red, puffy gums that bleed when you brush) can seem minor.
Periodontitis is a different situation. The infection has moved below the gumline, creating pockets between your teeth and gums where bacteria thrive. Over time, bone loss happens gradually, and the ligaments that anchor teeth in place break down. This stage is not reversible. The bone that’s lost doesn’t grow back on its own. But with treatment, you can halt the destruction, shrink those pockets, and keep your teeth for decades. In long-term studies tracking patients through nearly 20 years of maintenance therapy, the annual tooth extraction rate stayed below 1% per year for the first 14 years, meaning most people who commit to treatment keep the vast majority of their teeth.
Deep Cleaning: The First Line of Treatment
The standard starting treatment for periodontitis is scaling and root planing, commonly called a deep cleaning. Unlike a regular dental cleaning that focuses above and just below the gumline, this procedure goes deeper into the pockets around your teeth. Your dental team removes hardened plaque (tarite) and bacterial deposits from the root surfaces, then smooths the roots so your gums can reattach more snugly to the tooth.
The procedure is usually done under local anesthesia, sometimes one quadrant of your mouth at a time. Afterward, your gums will feel sore, swollen, and sensitive for the first few days. Within one to two weeks, that sensitivity gradually fades. You’ll notice your gums becoming less swollen, bleeding less, and feeling firmer around your teeth. By two to three weeks, most patients see significantly healthier gums. If you have more advanced disease, full healing can take several weeks to months before your gums are completely stable.
Your dentist will typically schedule a re-evaluation four to six weeks later to measure your gum pockets again and assess how well the tissue has responded. Many cases of moderate periodontitis improve enough with deep cleaning alone that no further procedures are needed.
Localized Antibiotics for Stubborn Pockets
When certain pockets don’t respond well enough to deep cleaning on its own, your dentist may place a localized antibiotic directly into the pocket. This delivers a concentrated dose of medication right where the infection lives, rather than relying on an oral antibiotic that circulates through your entire body.
One well-studied option uses tiny antibiotic-containing microspheres placed at the base of the pocket. The microspheres dissolve slowly over time, releasing medication directly into the infected area. In clinical trials, patients who received deep cleaning plus this localized antibiotic had significantly greater pocket depth reduction than those who had deep cleaning alone. After nine months, 61% of treated sites showed pocket depth reductions greater than 2 millimeters. The benefit was especially notable for smokers, who saw 32% greater pocket reduction when the antibiotic was added to their deep cleaning compared to deep cleaning alone.
The placement itself is quick and painless. Your hygienist inserts a small cartridge tip into the pocket and deposits the powder. No additional anesthesia is usually needed beyond what was used for the deep cleaning.
Surgical Options for Advanced Cases
If deep cleaning and antibiotics don’t bring pockets to a manageable depth, surgery becomes the next step. The two main options are traditional osseous (bone) surgery and laser-assisted treatment.
Traditional Osseous Surgery
In this procedure, your periodontist folds back the gum tissue to access the bone underneath, removes bacteria and damaged tissue, and reshapes the bone to eliminate the deep pockets where bacteria collect. Recovery takes at least a week, and you can expect bleeding, soreness, swelling, bruising, and sensitivity during that time.
Laser Surgery (LANAP)
A newer alternative uses a specialized laser to target the bacteria causing gum pockets without cutting or stitching the gum tissue. The laser can also stimulate regeneration of diseased gum tissue. Most people return to normal activities within a day, with only mild bleeding, swelling, or sensitivity. One study of 22 patients with chronic periodontitis found a 93.5% success rate with this approach. The trade-off is that not every case qualifies for laser treatment, and availability varies by practice.
What You Do at Home Matters Most
Professional treatment removes the bacteria and damage that have already accumulated, but what happens between appointments determines whether the disease stays controlled or comes back. Periodontal disease is driven by bacterial plaque, and plaque re-forms within hours of cleaning your teeth. Your daily routine is the single biggest factor in long-term outcomes.
Brush twice a day with a soft-bristled or electric toothbrush, angling the bristles toward the gumline where bacteria collect. Floss or use an interdental brush once daily to clean the spaces your toothbrush can’t reach. If your dentist has recommended an antimicrobial mouth rinse, use it as directed, but don’t treat it as a substitute for mechanical cleaning. Rinsing alone can’t break up the sticky film of plaque the way physical brushing and flossing can.
Smoking is one of the strongest risk factors for periodontitis and significantly slows healing after treatment. If you smoke, quitting will improve your gum health more than almost any other single change you can make.
The Maintenance Schedule That Prevents Relapse
Once your active treatment is complete, you move into a long-term maintenance phase. The American Academy of Periodontology recommends that anyone with a history of periodontitis have professional maintenance cleanings at least four times per year, spaced about three months apart. This is more frequent than the standard twice-yearly cleaning recommended for people without gum disease, and for good reason: periodontal pockets can harbor new bacterial growth quickly, and catching early signs of relapse at three-month intervals significantly reduces the likelihood of disease progression.
These maintenance visits aren’t just regular cleanings. Your hygienist will measure pocket depths, check for bleeding, assess whether any areas are losing attachment, and clean below the gumline in problem spots. Think of it as ongoing monitoring paired with targeted cleaning. Some patients eventually shift to longer intervals if their disease stays well controlled, but many need the three-month schedule indefinitely.
Healing Expectations by Timeline
Knowing what to expect after treatment helps you stay on track and recognize when something isn’t healing as it should.
- First 24 to 48 hours: The most critical healing window. Stick to soft foods, avoid hot liquids, and don’t brush directly on treated areas.
- Days 3 to 7: Swelling decreases, bleeding slows, gums start feeling firmer.
- Weeks 1 to 2: Sensitivity gradually fades. You can usually resume normal brushing and flossing.
- Weeks 2 to 3: Gums are typically significantly healthier, with noticeably less redness and puffiness.
- Weeks 4 to 6: Follow-up appointment to re-measure pockets and determine if further treatment is needed.
- Months 2 to 6: For advanced cases, full gum stability may take this long. Continued improvement is normal during this period.
Periodontitis is a chronic condition, similar to managing high blood pressure or diabetes. You won’t “get rid of it” in the sense of erasing all damage that’s occurred, but you can stop it from progressing, restore your gums to a healthy and stable state, and keep your teeth. The combination of professional treatment and consistent daily care is what makes that possible.
