Dentists treat gingivitis primarily by physically removing the plaque and tartar buildup that’s causing your gum inflammation. In mild cases, a standard professional cleaning is enough. When buildup has spread below the gumline, a deeper cleaning called scaling and root planing is the go-to treatment. Most people see their gums return to normal within one to two weeks after treatment.
How Your Dentist Diagnoses Gingivitis
Before any treatment begins, your dentist examines your gums for signs of inflammation: redness, swelling, and whether they bleed easily when touched. They’ll use a small probe to measure the space between your teeth and gums. Healthy gums sit snugly against teeth, but inflamed gums pull away slightly, forming pockets where bacteria collect. Your dentist also checks for tartar buildup, which is hardened plaque that can’t be brushed away at home.
Crooked teeth, poorly fitting crowns, or old dental work can also trap plaque in hard-to-reach spots. If your dentist identifies any of these as contributing factors, fixing them may be part of the treatment plan.
Standard Cleaning for Early Gingivitis
If your gingivitis is caught early and hasn’t progressed much, a routine dental cleaning (called a prophylaxis) may be all you need. This is the same type of cleaning many people get twice a year. Your hygienist scrapes plaque and tartar off the surfaces of your teeth using hand instruments, an ultrasonic scaler, or both. The ultrasonic scaler uses vibrations and a stream of water to break up deposits, and most patients find it more comfortable than manual scraping.
Both methods produce comparable results. Research comparing ultrasonic and manual instruments has found no meaningful difference in clinical outcomes. Ultrasonic scalers may cause slightly less discomfort, and newer micro-ultrasonic tips can reach tight spots like deep grooves between roots more effectively. But the end result is the same: a clean tooth surface that your gums can heal against.
Scaling and Root Planing for Deeper Buildup
When plaque and tartar have crept below the gumline into those pockets around your teeth, a standard cleaning won’t reach deep enough. Scaling and root planing is a more thorough procedure that cleans all the way down to the bottom of each pocket. It’s often done in two visits, treating one side of the mouth at a time.
The scaling portion removes tartar and bacteria from tooth surfaces both above and below the gumline. Root planing follows: your hygienist smooths out rough spots on the root surfaces. This matters because rough roots give bacteria a foothold to reattach. Smoothing them encourages your gums to heal and tighten back against the tooth.
Your dentist or hygienist will numb your gums with local anesthesia before the procedure, so you shouldn’t feel pain during treatment. Afterward, you can expect some tenderness and mild bleeding for the first 24 to 48 hours. Gums generally take five to seven days to feel normal again, with complete healing in one to two weeks depending on how severe the inflammation was. As the infection clears, swollen gums will shrink back to a healthier, tighter fit around your teeth.
Prescription Mouthwash
Your dentist may prescribe an antimicrobial mouth rinse to use alongside the cleaning. The most common prescription option contains chlorhexidine, a bacteria-killing agent that’s stronger than anything available over the counter. The typical routine is swishing for 30 seconds, twice a day. You use it full strength without diluting it with water, and spit it out rather than swallowing.
This rinse helps knock back bacteria while your gums are healing, especially in the days right after a deep cleaning. It can temporarily stain teeth and alter taste, so it’s used for a limited period rather than indefinitely.
Laser-Assisted Treatment
Some dental offices use diode lasers as an add-on to scaling and root planing. The laser targets bacteria inside gum pockets and can help reduce inflammation beyond what mechanical cleaning achieves alone. Studies have found that combining scaling with laser treatment or a light-based antibacterial therapy (photodynamic therapy) improves outcomes compared to scaling alone. That said, scaling and root planing remains the gold standard. Lasers are supplemental, not a replacement.
Fixing Problems That Trap Plaque
Sometimes the issue isn’t just hygiene but anatomy or dental work that makes cleaning difficult. Crowded or overlapping teeth create narrow spaces where a toothbrush and floss can’t reach well. A crown with a rough margin or a bridge that doesn’t fit flush against the gum can collect bacteria underneath. If your dentist identifies these structural contributors, they’ll recommend addressing them. That might mean replacing an old restoration, adjusting a rough edge, or in some cases discussing orthodontic options to reduce crowding.
What Your Dentist Expects You to Do at Home
Professional treatment removes the existing buildup, but gingivitis comes back if the daily plaque cycle isn’t interrupted at home. Your dentist or hygienist will tailor a home care plan based on your specific situation rather than just telling you to “brush and floss more.” This might include recommending a specific type of toothbrush (electric brushes tend to remove more plaque), demonstrating a brushing technique that reaches your gumline, or suggesting an interdental tool that fits your mouth better than traditional floss.
The American Dental Association emphasizes that effective home care looks different for each person. For some people, a water flosser or small interdental brush works better than string floss, and a dentist who understands your habits and motivation can guide you toward what you’ll actually stick with. The goal is daily disruption of the bacterial film on your teeth, especially along and just below the gumline where gingivitis starts.
How Long Recovery Takes
After a routine cleaning for mild gingivitis, most people notice less bleeding when they brush within a few days. After scaling and root planing, the timeline is slightly longer. Expect sensitivity to hot and cold foods for a few days, mild gum soreness, and some bleeding when brushing for the first day or two. By five to seven days, most discomfort is gone. Full tissue healing and gum reattachment can take up to two weeks.
Your dentist will likely schedule a follow-up visit a few weeks after treatment to check how your gums are responding. They’ll re-measure pocket depths and look for reduced bleeding and swelling. If the gums have responded well, you’ll move into a maintenance schedule of regular cleanings, typically every three to six months rather than the standard twice-a-year interval, at least until your gum health has been stable for a while. Gingivitis is fully reversible, but only if plaque doesn’t get the chance to build up again.
