Dentists treat gingivitis primarily by removing the plaque and hardite tartar buildup that’s causing your gum inflammation, then helping you keep it from coming back. For mild cases, a standard professional cleaning is often enough to reverse the condition entirely. More advanced gingivitis may require a deeper cleaning under local anesthesia, prescription mouth rinses, or localized antibiotics placed directly into the gum pockets.
How Dentists Diagnose Gingivitis
Before any treatment begins, your dentist needs to figure out how far the inflammation has progressed. The key tool is a thin metal probe that gets gently inserted between your gum and each tooth to measure the depth of the pocket. In a healthy mouth, that gap is 1 to 3 millimeters. Once pockets reach 4 millimeters or deeper, the concern shifts from gingivitis to periodontitis, a more serious form of gum disease where bone loss can occur.
Your dentist or hygienist will also check for bleeding by running the probe along the gum line around each tooth. They look at four spots per tooth and note which ones bleed, which gives them a percentage score that reflects how widespread the inflammation is. X-rays may be taken to check whether the bone supporting your teeth has started to break down, which would change the treatment plan significantly.
Standard Professional Cleaning
For early gingivitis, the first line of treatment is a routine prophylaxis cleaning. Your hygienist uses special instruments to scrape away plaque (the soft bacterial film) and tartar (the hardite calcified deposits that brushing can’t remove) from your teeth above the gum line. Some offices use ultrasonic tools that vibrate at high frequency to break up tartar more efficiently, while others rely on hand-held scalers, or a combination of both.
After the scraping is done, they polish your teeth with a gritty paste applied with a small rotating brush. This smooths the tooth surfaces and removes surface stains, which also makes it harder for bacteria to cling to your teeth in the weeks that follow. The whole visit typically takes 30 to 60 minutes, and there’s no anesthesia involved for a standard cleaning.
Deep Cleaning for More Advanced Cases
If tartar has built up below the gum line or your pockets are deeper than normal, your dentist will recommend scaling and root planing. This is essentially a more aggressive version of a standard cleaning that reaches underneath your gums.
The procedure has two parts. Scaling removes plaque and tartar from both above and below the gum line. Root planing goes a step further by smoothing the rough spots on your tooth roots, which eliminates places where bacteria tend to collect and helps your gums reattach more tightly to the teeth. Because the instruments go deeper, you’ll get local anesthesia to numb the area first. For people with widespread buildup, the procedure is sometimes split across two visits, treating one side of the mouth at a time.
You can expect some soreness and gum sensitivity for a few days afterward. Your gums may bleed a bit when you brush during the first week, but inflammation typically starts improving within the first couple of weeks. Your dentist will schedule a follow-up visit to re-measure your pocket depths and check whether the tissue is healing properly.
Prescription Mouth Rinses
Dentists sometimes prescribe an antimicrobial mouth rinse to use alongside cleaning, particularly when inflammation is widespread or slow to improve. The most common prescription rinse contains chlorhexidine, which kills bacteria more effectively than over-the-counter mouthwash. You rinse with about half an ounce (15 mL) twice a day, swishing for 30 seconds, then spitting it out. The timing matters: you use it after brushing in the morning and evening, but you shouldn’t rinse with water, eat, or brush again right after using it, because that washes away the active ingredient before it has time to work.
Chlorhexidine can cause temporary brown staining on teeth and alter your sense of taste while you’re using it. These side effects go away once you stop, and your dentist will typically limit the prescription to a few weeks rather than long-term use.
Localized Antibiotics
For stubborn pockets that don’t respond well to cleaning alone, dentists can place antibiotic medication directly into the gum pocket. These come in several forms: tiny gel-filled syringes, dissolvable chips, or microspheres that release medication slowly over days to weeks. The antibiotic sits right at the infection site, which delivers a much higher concentration of medication to the area than an oral pill would.
This is typically done right after a scaling and root planing session. Your dentist applies the material into the pocket, and it dissolves on its own over the following week or two. You won’t need to have it removed. This approach is reserved for specific problem areas rather than being applied to every tooth.
Laser Treatment
Some dental offices use lasers as an alternative or supplement to traditional scaling. During laser therapy, the dentist directs a focused beam of light into the gum pocket to remove inflamed tissue and kill bacteria. The tartar and plaque are then cleared away, and rough spots on the tooth root are smoothed, just as in conventional deep cleaning. Laser treatment tends to cause less bleeding and swelling, though it’s not available at every practice and may cost more than standard scaling and root planing.
What Happens After Treatment
Gingivitis is one of the few dental conditions that’s fully reversible with proper care. After treatment, your dentist will likely want to see you more frequently than the typical twice-a-year schedule, at least until your gum health stabilizes. Some people are put on a three- or four-month cleaning cycle. The exact interval depends on how severe the inflammation was and how well your gums respond to treatment.
The cleaning your dentist does only addresses the buildup that’s already there. What keeps gingivitis from coming back is daily home care: brushing twice a day with a soft-bristled brush, flossing or using interdental brushes to clean between teeth, and using any prescribed rinses as directed. Your dentist will review your brushing technique if needed, because even small changes in angle or pressure can make a noticeable difference in plaque removal.
If your gums don’t improve after the initial round of treatment, or if pocket depths continue to increase at follow-up visits, your dentist may refer you to a periodontist, a specialist focused specifically on gum disease. This is more common when gingivitis has started progressing toward periodontitis, where the supporting bone around the teeth is at risk.
