Gingivitis is treated by removing the bacterial buildup that causes gum inflammation, both through professional cleaning and consistent daily care at home. Most cases of mild to moderate gingivitis start improving within about two weeks of effective treatment. The good news is that gingivitis is fully reversible, unlike its more advanced form, periodontitis, which causes permanent damage to the bone supporting your teeth.
Why Treatment Works
Gingivitis is your body’s inflammatory response to a sticky film of bacteria (plaque) that builds up along and under the gumline. When that bacterial layer is disrupted and removed, the inflammation stops. Your gums heal. It’s that straightforward in principle, though the execution requires consistency.
When plaque isn’t removed, it hardens into tarite (also called calculus), which you can’t brush away yourself. That’s where professional treatment comes in. Once the hardened deposits are gone and you keep new plaque from accumulating, your gums return to a healthy pink, firm state.
Professional Cleaning Options
For mild or localized gingivitis, a standard dental cleaning (prophylaxis) is usually enough. Your hygienist removes plaque and tartar from above and just below the gumline, then polishes the tooth surfaces to make it harder for bacteria to reattach.
If you have widespread, moderate to severe gum inflammation, with redness, swelling, and bleeding across 30% or more of your teeth, your dentist may recommend a more intensive therapeutic cleaning. This goes beyond a routine visit. The American Dental Association classifies this as a specific procedure designed to remove all deposits and promote tissue healing in patients who have swollen gums and generalized bleeding on probing but haven’t yet progressed to periodontitis.
In cases where tartar has built up well below the gumline, the next step is scaling and root planing, sometimes called a deep cleaning. Your gums are numbed with local anesthesia, then your provider uses hand instruments or ultrasonic tools to scrape away deposits from below the gumline and smooth the root surfaces. Smoothing the roots helps your gums reattach to the teeth and discourages bacteria from colonizing again. Depending on severity, this may be done in one visit or split across two to four appointments by mouth quadrant. Your provider may also apply a localized antibiotic around the tooth roots afterward.
What You Do at Home Matters Most
Professional cleaning removes the existing buildup, but what you do every day determines whether gingivitis comes back. Plaque re-forms within hours of brushing, so daily disruption of that bacterial film is the core of treatment.
Brushing
Brush twice a day for two minutes, angling your bristles toward the gumline at about 45 degrees. A soft-bristled or electric toothbrush works well. Your choice of toothpaste also matters. Toothpastes containing stannous fluoride have shown meaningful results in clinical trials: one randomized study found roughly 30% fewer bleeding sites after just two to three weeks of twice-daily use compared to a standard fluoride toothpaste. Look for this ingredient on the label if bleeding gums are your main concern.
Cleaning Between Teeth
Brushing alone misses the surfaces between your teeth, which is exactly where gingivitis often starts. You need to clean these gaps daily, but traditional floss isn’t your only option.
Interdental brushes, those tiny bottle-brush-shaped picks you slide between teeth, are actually more effective than floss at reducing both bleeding and plaque between teeth. A systematic review of clinical trials found statistically significant advantages for interdental brushes over floss across four to twelve weeks of use. If your teeth have enough space between them for the brush to fit without forcing, they’re a better choice. For tight contacts where an interdental brush won’t pass through, floss or a water flosser works.
Therapeutic Mouthwash
Mouthwash is a useful supplement to brushing and cleaning between teeth, not a replacement. Two active ingredients have the strongest clinical backing for gingivitis.
- Chlorhexidine is the most studied and most effective. A Cochrane review of 12 trials with 950 participants found it produced a large reduction in plaque when used daily for four to six weeks alongside regular brushing, and measurable reductions in gum inflammation that held steady at six months. It’s typically available by prescription and can cause temporary tooth staining with prolonged use, so dentists generally recommend it for short courses during active treatment.
- Cetylpyridinium chloride (CPC) is available over the counter in many antiseptic mouthwashes. It also reduces plaque and gum inflammation significantly compared to placebo, including at the hard-to-reach surfaces between teeth. It’s a solid option for ongoing daily use without a prescription.
How Quickly Gums Heal
With consistent treatment, you can expect to see noticeable improvement in about two weeks. Bleeding when you brush or floss is typically one of the first symptoms to fade. Redness and puffiness take a bit longer to resolve fully, but most people with mild to moderate gingivitis see their gums return to a healthy state within two to four weeks of daily care combined with professional cleaning.
If you’ve just had a deep cleaning, your gums may feel tender or sensitive for a few days afterward. Some people notice mild bleeding or soreness that subsides within a week. Your dentist will usually schedule a follow-up visit to check how your gums are responding and determine whether additional treatment is needed.
What Happens If Gingivitis Isn’t Treated
Left unchecked, gingivitis can progress to periodontitis, where inflammation pushes deeper and begins attacking the soft tissue and bone that hold your teeth in place. The pockets between your teeth and gums, which are normally one to three millimeters deep, can grow to several millimeters or even more than a centimeter. At that point, the damage to the jawbone is irreversible. Periodontitis is the leading cause of tooth loss in adults.
The critical distinction is that gingivitis affects only the gum tissue and is completely reversible. Periodontitis involves bone loss and is not. Treating gingivitis early is one of the most straightforward things you can do to protect your teeth long-term.
How Often You Need Professional Cleanings
There’s no universal schedule. The standard recommendation of every six months works for many people, but if you’re prone to heavy plaque buildup or have a history of gum problems, your dentist may suggest every three to four months until your gums stabilize. After a therapeutic cleaning for moderate or severe gingivitis, there’s no set waiting period before returning to a regular preventive schedule. Your dentist evaluates your tissue healing and decides when you’re ready to step down to routine maintenance.
