Swollen gums can develop for several reasons, including plaque buildup, irritation, gum disease, hormonal changes, certain medications, or a problem around one tooth. The swelling may affect a small area or a larger part of the gumline and may occur with redness, tenderness, bleeding, or sensitivity.
If you are asking why are my gums swollen, the pattern of swelling and any related symptoms can offer useful clues. However, persistent, worsening, or painful swelling should be evaluated by a dentist so the underlying cause can be identified.
Why Are My Gums Swollen?
Gums become swollen when the tissue is irritated or inflamed. Common causes include:
- Plaque buildup: Plaque along the gumline can irritate the gums and contribute to gingivitis.
- Gingivitis: Early gingivitis can cause swollen, red, or bleeding gums and may improve with timely professional care and better daily oral hygiene.
- Food trapped between teeth: Food debris can irritate the gum around one or two teeth.
- Aggressive brushing: Brushing too hard or using a hard-bristled toothbrush may irritate sensitive gum tissue.
- Dental appliances: Poorly fitting dentures, retainers, or other appliances can rub against the gums.
- Hormonal changes: Pregnancy and other hormonal changes can make gums more sensitive to plaque and inflammation.
- Certain medications: Some medicines can affect gum tissue or contribute to dry mouth, which may influence oral health.
- Nutritional deficiencies: Severe deficiencies, including vitamin C deficiency, can affect gum health.
- Tobacco use: Smoking and other tobacco products increase the risk of gum disease.
- Dental infection: An infection involving a tooth or the surrounding tissues can cause localized swelling.
Because several conditions can produce similar symptoms, the cause is not always clear from appearance alone.
Plaque buildup along the gumline can contribute to gingivitis, which may cause swollen, red, or bleeding gums. The National Institute of Dental and Craniofacial Research explains that plaque-related gingivitis can progress if plaque and tartar are not adequately controlled.
How Are Swollen Gums Treated?
Swollen gums treatment depends on the cause and the condition of the surrounding teeth and gums.
Professional Dental Cleaning
If plaque and tartar are contributing to gum inflammation, a professional dental cleaning can remove deposits that cannot be removed with regular brushing and flossing alone.
Scaling and Root Planing
If gum disease extends below the gumline, scaling and root planing may be recommended. This deeper cleaning removes plaque and tartar from tooth and root surfaces.
Periodontal Care
Patients with periodontitis may need periodontal maintenance or additional gum treatment based on the extent of the disease.
Treatment of a Tooth-Related Problem
If swelling is linked to a damaged tooth, infection, poorly fitting restoration, or another dental issue, treatment focuses on addressing that underlying cause.
Regular brushing, cleaning between the teeth, and professional dental care can help reduce the risk of gum disease. The CDC also emphasizes good oral hygiene and regular dental care as important steps for maintaining gum health.
Why Are My Gums Swollen on One Side?
Swelling on one side of the mouth or around a single tooth often points to a local source. A piece of food trapped between teeth may irritate the gum, while decay, a cracked tooth, a periodontal pocket, or an infection can also cause swelling in one area.
Watch for symptoms such as pain when biting, sensitivity, drainage, a bad taste, or worsening tenderness. These may indicate that the problem involves more than surface irritation.
Gentle brushing and flossing can help if food debris is present, but avoid repeatedly pressing or picking at the swollen area. If the swelling does not improve, keeps returning, or becomes painful, a dental examination is appropriate.
How Can I Care for Swollen Gums at Home?
Home care may help when swelling is mild and related to plaque or temporary irritation, but it should not replace professional care when symptoms persist.
You can:
- Brush twice daily with a soft-bristled toothbrush and fluoride toothpaste.
- Clean between your teeth once a day with floss or another interdental cleaner.
- Use gentle pressure when brushing and flossing.
- Rinse with warm salt water if it feels soothing.
- Drink water regularly to help prevent dry mouth.
- Avoid smoking and other tobacco products.
- Keep dentures, retainers, and removable appliances clean.
Avoid placing aspirin, strong antiseptics, alcohol, or other harsh household products directly on swollen gums because they can irritate the tissue.
If your gums remain swollen despite consistent home care, the cause may need professional evaluation.
When Should I See a Dentist for Swollen Gums?
See a dentist if swelling persists, frequently returns, or is accompanied by other symptoms.
Arrange an evaluation if you notice:
- Frequent bleeding during brushing or flossing
- Persistent gum tenderness or redness
- Swelling around one particular tooth
- Pus or drainage near the gumline
- A persistent bad taste or bad breath
- Gums pulling away from the teeth
- Pain when chewing
- Loose or shifting teeth
Seek prompt dental or medical attention for rapidly increasing facial swelling, fever with dental swelling, difficulty swallowing or breathing, or uncontrolled bleeding.
A dental examination can help determine whether the problem is related to gingivitis, periodontitis, a tooth infection, irritation, or another cause.
The Bottom Line
Swollen gums can result from plaque buildup, gingivitis, localized irritation, hormonal changes, certain medications, or a dental infection. Mild irritation may improve with gentle brushing, daily cleaning between the teeth, and good oral hygiene, but persistent swelling deserves attention. The right treatment depends on the underlying cause rather than the swelling itself. If your gums continue to swell, bleed, become painful, or develop drainage, a dental examination can help identify the problem and determine whether professional cleaning, periodontal care, or another treatment is needed.

FAQs
Why Are My Gums Swollen Even Though I Brush and Floss?
Brushing and flossing are important, but gum swelling can still occur because of tartar buildup, gum disease, hormonal changes, certain medications, a dental infection, or irritation around one tooth. Technique also matters, especially when plaque remains along the gumline or between teeth. Recurring swelling should be checked by a dentist.
How Long Do Swollen Gums Last?
There is no fixed timeline because recovery depends on the cause. Mild irritation may improve after the source is removed, while swelling related to gingivitis, periodontitis, or infection may continue until the underlying problem is addressed. If swelling persists or worsens, have it evaluated.
Can Swollen Gums Go Away on Their Own?
Temporary irritation may settle once you remove the cause. However, swelling from plaque-related gingivitis, gum disease, or infection may require improved oral hygiene, a professional cleaning, or other dental treatment. Do not rely on home care alone if symptoms persist or worsen.
