If you have gum disease, the single most important thing to do is get a professional cleaning and then commit to a daily routine that keeps bacteria from rebuilding. Gum disease caught early (gingivitis) can be fully reversed within days to weeks. More advanced disease (periodontitis) can’t be reversed, but it can be stopped and managed so you keep your teeth. Here’s what to do at each stage.
Figure Out Which Stage You’re Dealing With
Gum disease exists on a spectrum, and what you need to do depends on where you fall. Gingivitis is the early stage. The main signs are red, swollen gums that bleed when you brush or floss, sometimes for no obvious reason at all. It generally doesn’t hurt, which is why many people don’t realize they have it. At this point, no permanent damage has occurred.
Periodontitis is what happens when gingivitis goes untreated. The inflammation starts attacking the soft tissue and bone that hold your teeth in place. You’ll notice your gums pulling away from your teeth, creating gaps called periodontal pockets that can grow several millimeters deep, sometimes more than a centimeter. Other signs include persistent bad breath, sensitive teeth, gums that look like they’re receding (making your teeth appear longer), and teeth that shift position or feel loose. At an advanced stage, the jawbone itself breaks down and tooth roots become exposed.
Your dentist measures those pocket depths with a small probe during a routine exam. That measurement, along with X-rays showing any bone loss, determines your stage and shapes the treatment plan.
Get a Professional Cleaning
No amount of brushing at home can remove tartar, the hardite buildup of mineralized plaque that sits above and below your gumline. A professional cleaning is the non-negotiable first step.
For gingivitis, a standard cleaning is usually enough. The Mayo Clinic notes that with professional cleaning followed by consistent brushing and flossing, healthy gum tissue can return within days or weeks.
For periodontitis, you’ll need a deeper procedure called scaling and root planing. Your gums are numbed with local anesthesia, then the dentist or hygienist uses hand instruments or ultrasonic tools to scrape plaque and tartar from below the gumline (scaling) and smooth the rough surfaces of your tooth roots (planing). That smooth surface makes it harder for bacteria to reattach and helps your gums heal tightly against the tooth again. Your dentist may also place antibiotics directly around the tooth roots or prescribe oral antibiotics to knock out remaining infection.
After a deep cleaning, expect some tenderness and sensitivity. Your gums may feel swollen for a few days, and your teeth might feel slightly loose at first. That looseness resolves as the gums tighten back up around the teeth. The swelling shrinks once the infection clears.
Understand the Surgical Options
If scaling and root planing doesn’t bring your pocket depths under control, the next step is a surgical procedure. Two main approaches exist: traditional flap surgery and laser treatment.
In flap surgery, a periodontist lifts the gum tissue back to access and clean deep pockets, then repositions the gums snugly around the teeth. In some cases, bone grafts or tissue grafts are placed to rebuild what’s been lost.
A newer option called LANAP (laser-assisted new attachment procedure) uses a laser beam to destroy bacteria and remove damaged tissue while leaving healthy tissue intact. Research comparing LANAP to scaling and root planing alone found that LANAP reduced periodontal pocket depth by about 44% on average, compared to roughly 40% with scaling and root planing. LANAP also showed a slightly greater reduction in bleeding and plaque. The key advantage is that the laser stimulates new connective tissue attachment to the root surface, essentially encouraging your body to regenerate what was lost, without the cutting and stitching of traditional surgery.
Fix Your Daily Brushing Technique
Most people brush their teeth but miss the area that matters most for gum disease: the tiny crevice where your gum meets your tooth. Bacteria collect there and form the plaque that triggers inflammation.
The most effective technique for targeting this area is to angle your toothbrush bristles at 45 degrees toward the gumline, then use short back-and-forth strokes. This pushes the bristles gently into the space between the gum and tooth, dislodging plaque that upright brushing misses. Use a soft-bristled brush so you don’t damage already-irritated tissue, and brush for a full two minutes twice a day.
Flossing matters just as much. The spaces between your teeth are where plaque builds up undisturbed. If traditional floss is difficult, interdental brushes (tiny bottle-brush-shaped picks) or a water flosser work well, especially if you have wider gaps from gum recession. The tool matters less than the consistency.
Stick to a Maintenance Schedule
Once you’ve had periodontitis, you can’t go back to annual or twice-yearly cleanings and expect things to hold. The American Academy of Periodontology recommends that most patients with a history of periodontitis start with cleanings every three months. Your dentist may adjust that interval over time based on how your gums respond, but three to four months is the standard starting point.
These maintenance visits aren’t just cleanings. Your dentist re-measures pocket depths, checks for new bone loss, and catches any regression before it becomes serious. Skipping these appointments is one of the most common reasons people lose ground after successful treatment.
Address Risk Factors That Feed the Disease
Gum disease is driven by bacteria, but certain factors make your body worse at fighting the infection or faster at losing tissue.
Smoking is the most significant modifiable risk factor. It reduces blood flow to the gums, slows healing, and makes treatment less effective. The current classification system used by periodontists explicitly factors smoking status into how aggressively your disease is expected to progress. Quitting changes the trajectory.
Diabetes and gum disease have a two-way relationship. Poorly controlled blood sugar fuels gum inflammation, and gum inflammation makes blood sugar harder to control. A meta-analysis published in Diabetes Care found that treating periodontitis in people with type 2 diabetes lowered their HbA1c (a key blood sugar marker) by an average of 0.40 percentage points compared to no treatment. That improvement lasted at least three months. A 0.40% drop may sound small, but in diabetes management, reductions of that size are clinically meaningful and comparable to what some medications achieve.
Stress, hormonal changes (pregnancy, menopause), and certain medications that cause dry mouth also increase susceptibility. You can’t always eliminate these factors, but being aware of them helps you and your dentist calibrate how aggressive your prevention needs to be.
Know What Realistic Recovery Looks Like
Gingivitis is fully reversible. With professional cleaning and improved home care, you can expect your gums to stop bleeding and return to a healthy pink within a few weeks.
Periodontitis is a different story. Once bone is lost, it doesn’t grow back on its own (though procedures like LANAP or bone grafting can partially rebuild it). The realistic goal with periodontitis is to halt the progression, shrink pockets, and maintain what you have. Many people live with well-managed periodontitis for decades without losing teeth, as long as they stay on their maintenance schedule and keep up daily care.
The gum tissue itself will change shape as it heals. Swollen gums that once covered your teeth will tighten and recede as inflammation resolves, which can make your teeth look longer and feel more sensitive to temperature. This is a sign of healing, not worsening. Your dentist can recommend desensitizing products if the sensitivity is bothersome.
