Dentists treat gingivitis primarily through professional cleaning to remove the plaque and tartar buildup causing inflammation. Most mild cases improve within 10 to 14 days after treatment, combined with better brushing and flossing at home. The specific procedure your dentist uses depends on how widespread and severe the inflammation is.
How Dentists Diagnose Gingivitis
Before choosing a treatment, your dentist needs to confirm gingivitis and rule out periodontitis, a more advanced form of gum disease that involves bone loss. They do this by measuring the small gap between your teeth and gums with a thin probe. Healthy gums sit snugly against the tooth, but inflamed gums pull away slightly, creating pockets. Probing depths of 3 millimeters or less are normal. Anything deeper suggests the disease may have progressed beyond gingivitis.
Your dentist will also check for bleeding on probing, the single most reliable sign of active gum inflammation. They’ll note the color and texture of your gums (healthy tissue is firm and pink, while inflamed tissue is red, puffy, and shiny) and look at X-rays to confirm no bone loss has occurred. This distinction matters because gingivitis is fully reversible, while periodontitis is not.
Standard Cleaning for Mild Gingivitis
If your gingivitis is mild and limited to a few areas, a standard prophylaxis (the regular cleaning you’d get at a checkup) is usually enough. Your hygienist uses hand scalers or ultrasonic instruments to scrape plaque and hardened tartar off your teeth, both above and just below the gumline. Ultrasonic tools vibrate rapidly and use water to flush debris away, making them effective at breaking up stubborn calculus.
This is the same cleaning most people get every six months, but for someone with early gingivitis, it serves a therapeutic purpose. Once the tartar is removed, the gums can reattach snugly to the tooth surface and inflammation starts to subside. The procedure takes 30 to 60 minutes and is generally painless, though you might feel some sensitivity if your gums are already irritated.
Full-Mouth Scaling for Moderate to Severe Cases
When inflammation is more widespread, affecting 30 percent or more of your teeth, and your gums bleed readily during the exam, your dentist may recommend a more intensive cleaning classified as scaling in the presence of generalized moderate or severe gingival inflammation. The American Dental Association distinguishes this from a routine cleaning because the level of disease demands more thorough treatment. Unlike a standard prophylaxis, this procedure targets both above and below the gumline across the entire mouth, removing calculus deposits that a regular cleaning wouldn’t fully address.
The key distinction here is that this procedure is still for gingivitis, not periodontitis. Your dentist has confirmed there’s no attachment loss or bone damage. The gums are inflamed and bleeding, but the underlying structures are intact, which means the condition can still be completely reversed with proper treatment.
Deep Cleaning: Scaling and Root Planing
If gingivitis has been left untreated long enough that pockets have deepened and tartar has built up well below the gumline, your dentist may recommend scaling and root planing. This is a deeper procedure than a standard cleaning. Your dentist or hygienist uses hand scalers or ultrasonic instruments to clean all the way down to the tooth roots, reaching areas your toothbrush could never access.
Root planing is the second half of this process. After removing the tartar, your provider smooths the rough surfaces of your tooth roots. Bacteria tend to cling to rough spots, so smoothing them out helps your gums heal and reattach to the teeth. The mouth is typically treated in two visits, with one side done at each appointment under local anesthesia. You can expect some soreness and sensitivity for a few days afterward, but over-the-counter pain relief handles it for most people.
Prescription Mouth Rinse
Your dentist may prescribe an antimicrobial mouth rinse to use alongside professional cleaning. The standard prescription is a 0.12% chlorhexidine rinse, used twice daily, morning and evening after brushing. You swish one tablespoon of the undiluted rinse for 30 seconds, then spit it out.
Chlorhexidine is more potent than anything available over the counter. It kills the bacteria responsible for plaque formation and keeps bacterial levels low while your gums heal. Your dentist will typically prescribe it for a limited period, often two to four weeks, because long-term use can cause temporary tooth staining and alter your sense of taste. It’s a tool to get inflammation under control quickly, not a permanent addition to your routine.
Antibiotics for Severe Gingivitis
Oral antibiotics are rarely needed for typical gingivitis, but they become important in severe cases like acute necrotizing ulcerative gingivitis, a painful condition marked by ulcerated, bleeding gums and sometimes fever. This form of gingivitis involves a specific mix of bacteria that requires more aggressive treatment. Dentists typically prescribe antibiotics effective against common oral bacteria, and the course continues until 72 hours after symptoms resolve.
For standard gingivitis, antibiotics aren’t part of the treatment plan. Professional cleaning combined with improved home care is enough to eliminate the problem.
What You’ll Need to Do at Home
Professional cleaning removes the existing buildup, but gingivitis will come back if daily habits don’t change. Your dentist will walk you through proper brushing technique, which means angling the bristles toward the gumline at about 45 degrees and using gentle, short strokes rather than scrubbing back and forth. An electric toothbrush can help if your technique is inconsistent.
Flossing matters more than most people think. Plaque forms between teeth where bristles can’t reach, and this is often where gingivitis starts. Daily flossing, or using interdental brushes if the spaces between your teeth are wide enough, removes that plaque before it hardens into tartar. Once tartar forms, only a dental professional can remove it.
Recovery and Follow-Up
Mild gingivitis typically improves within 10 to 14 days of professional cleaning when paired with consistent home care. You’ll notice the bleeding stops first, followed by a gradual return to normal gum color and firmness. More severe cases take longer, sometimes several weeks, particularly if deep cleaning was required.
Your dentist will bring you back for a follow-up to check whether the inflammation has resolved. For someone whose gingivitis was caught early, returning to a standard six-month cleaning schedule is usually fine. If your case was more advanced, or if you have risk factors like diabetes or smoking that make recurrence more likely, your dentist may recommend cleanings every three to four months. The American Academy of Periodontology suggests that more frequent maintenance, at least four times per year, reduces the likelihood of gum disease progressing.
Bleeding on probing is the metric your dentist watches most closely at these follow-ups. Levels below 10 percent of sites indicate low risk, while bleeding at more than 30 percent of sites signals that more frequent care is needed. The goal is to keep your gums in a stable, inflammation-free state so gingivitis doesn’t progress to periodontitis, where the damage becomes permanent.
