Swollen Gums Behind Your Front Teeth: Why It Happens and How to Treat It
Table of Contents
Reviewed by Dr. Drew Endicott, Endicott Dental, Broken Arrow, OK. Updated September 23, 2026.
Swollen gums behind your front teeth are most often caused by plaque along the tongue side of the upper teeth, food or floss caught between two front teeth, or early gingivitis. Mild swelling that improves within a week of careful brushing and flossing is not a concern. Swelling that is painful, bleeds on its own, has a white or yellow bump, or lasts more than two weeks needs a dental exam, because it can mean an infection or gum disease that home care won’t clear.
At Endicott Dental in Broken Arrow, swollen-gum visits usually end in one of three ways: a professional cleaning, periodontal treatment if the pockets are deep, or treating an abscess. Below is how to tell which one you’re likely looking at.
Behind the upper front teeth: plaque and tartar build-up; fix = cleaning plus brushing the tongue side.
Between two front teeth: trapped food or a popcorn-hull-style irritant; fix = floss, warm salt water, 3–5 days.
One swollen bump with pain: possible abscess; see a dentist within 24–48 hours.
Swelling plus bleeding across several teeth: gingivitis or gum disease; needs a cleaning and a gum evaluation.
Schedule an exam if gum swelling lasts more than a few days or is paired with pain, bleeding, or infection symptoms. Early care can help prevent the problem from getting worse.

Common Causes of Swollen Gums
Swollen gums can happen for many reasons. Some causes are minor and temporary, while others need professional dental treatment.
Plaque and Tartar Buildup
One of the most common causes of swollen gums is plaque buildup along the gumline. When plaque is not removed with brushing and flossing, it can harden into tartar. Tartar traps bacteria against the gums and may lead to gingivitis or more advanced gum disease.
Professional teeth cleaning can remove hardened tartar and help reduce gum inflammation.
Gingivitis and Gum Disease
Gingivitis is the earliest stage of gum disease. It often causes redness, swelling, bleeding, and tenderness. If left untreated, gingivitis can progress into periodontitis, a more serious condition that can damage the gums, bone, and supporting structures around the teeth.
Patients with ongoing swelling may need periodontal treatment to control infection and protect their oral health.
Food Trapped Under the Gums
Food particles can become lodged beneath the gumline and cause irritation. This can happen around any tooth, including swollen gums behind front teeth. If flossing does not remove the debris or the swelling continues, a dentist may need to clean the area.
Brushing or Flossing Too Hard
Aggressive brushing or flossing can injure the gum tissue and cause swelling or bleeding. Using a soft-bristled toothbrush and gentle technique can help prevent irritation.
Dental Appliances
Dentures, bridges, braces, clear aligners, retainers, and other dental appliances can irritate the gums if they do not fit correctly. If gum swelling starts after wearing a new appliance, schedule a dental exam so your dentist can check the fit.
Infection or Abscess
Swollen gums can sometimes be caused by an infected tooth or gum abscess. This may cause pain, pus, a bad taste, fever, or swelling in the face or jaw. These symptoms should be treated quickly through emergency dentistry care.
Hormonal Changes, Medications, and Health Conditions
Pregnancy, certain medications, vitamin deficiencies, diabetes, immune conditions, and other health concerns can contribute to gum inflammation. Your dentist can help identify whether the swelling appears related to oral health or if you may need to speak with your physician. We cover the illness-related causes in Swollen Gums and Your Immune System.
How Dentists Treat Swollen Gums
The right swollen gums treatment depends on the cause and severity of the swelling. During your visit, your dentist will examine your gums, teeth, and surrounding tissues. X-rays may be recommended if infection, bone loss, or a tooth-related problem is suspected.
Professional Teeth Cleaning
If plaque and tartar buildup are causing irritation, a professional cleaning may help reduce swelling and bleeding. Cleanings remove bacteria from areas that are difficult to reach at home.
Periodontal Treatment
If gum disease is present, your dentist may recommend periodontal care. This may include deep cleaning, also called scaling and root planing, to remove bacteria and tartar beneath the gumline.
Antibiotics or Infection Care
If infection is present, antibiotics or additional dental treatment may be needed. Gum infections should not be ignored because they can spread and lead to more serious oral health problems.
Adjusting Dental Appliances
If a denture, bridge, aligner, or orthodontic appliance is irritating your gums, your dentist can check the fit and recommend adjustments.
Dental Exam and Diagnosis
A dental exam is the best way to find out why your gums are swollen. Your dentist can determine whether the issue is caused by gum disease, irritation, infection, injury, or another concern.

How to Reduce Gum Swelling at Home
Some mild gum swelling may improve with better oral hygiene and simple home care. You can try:
Brushing gently with a soft-bristled toothbrush
Flossing daily to remove plaque and food particles
Rinsing with warm salt water
Avoiding tobacco products
Avoiding very hot, spicy, or acidic foods if they irritate your gums
Using a cold compress if there is mild swelling outside the mouth
Home care can help with mild irritation, but it should not replace a dental visit if symptoms continue.
When to Schedule a Dental Exam
Schedule a dental exam if gum swelling lasts more than a few days, keeps coming back, or is paired with pain, bleeding, bad breath, pus, or loose teeth.
You should also call Endicott Dental if you have swollen gums behind front teeth that do not improve after flossing or rinsing. This could be caused by trapped food, tartar buildup, gum disease, or infection.
A dentist can identify the cause and recommend the right swollen gums treatment before the condition becomes more serious.
Preventing Swollen Gums and Gum Disease
Healthy gums start with consistent dental care. Brush twice a day, floss daily, and visit your dentist regularly for cleanings and exams.
To lower your risk of swollen gums:
Brush gently along the gumline
Floss between every tooth
Schedule routine teeth cleanings
Avoid smoking and tobacco use
Drink plenty of water
Treat gum disease early
Keep dental appliances clean and properly fitted
Routine visits allow your dentist to spot early gum problems before they lead to advanced periodontal disease or tooth loss.
Swollen Gums FAQ
Why are my gums swollen behind my front teeth?
The tongue side of the upper front teeth is where saliva flow is lowest and brushing is least thorough, so plaque hardens into tartar there and inflames the gum. Trapped food between the two front teeth and early gingivitis are the next most common causes.
How do I treat swollen gums behind my front teeth at home?
Brush the back of the front teeth at a 45-degree angle, floss gently, and rinse with warm salt water twice a day. If it isn’t clearly better in a week, book a cleaning.
When should I worry about swollen gums?
When the swelling is painful, has a pus-filled bump, bleeds without brushing, comes with a bad taste or fever, or lasts more than two weeks. Those are signs of infection or gum disease.
Can swollen gums go away on their own?
Mild swelling from plaque or trapped food usually does once the cause is removed. Swelling from tartar, gum disease or an abscess does not, because the cause stays until a dentist removes it.
What will the dentist do for swollen gums?
A cleaning to remove tartar, a gum measurement to check for periodontal disease, and, if there’s an infection, drainage or antibiotics. Most cases are handled in a single visit.
