Gum pain and itchy gums
Gum pain and itchy gums: causes, symptoms and what to do
Itchy gums most often come from plaque and gingivitis, injury, allergies, hormonal changes, dry mouth or ill-fitting dentures, and Healthline says to see a dentist if itching and other symptoms last about three days without improving. Pain in one spot, pus or swelling can mean an abscess, which needs a dentist. A minor gum cut typically heals in three to four days.
Why do my gums itch?
Healthline lists gum injuries from trauma, teeth grinding or vaping, plaque buildup and gingivitis, allergies to foods, medicines, pets or seasonal triggers, hormonal changes during pregnancy, puberty, menstruation or menopause, dry mouth from conditions or medications, and ill-fitting dentures or partials that trap food and bacteria. Our guide on swollen and bleeding gums covers gingivitis in more detail.
How to soothe itchy gums
Healthline suggests a salt water rinse of about a teaspoon of salt in 8 ounces of lukewarm water, sucking on ice cubes to cool the gums, brushing and flossing regularly, an alcohol-free antiseptic mouthwash if there is inflammation, quitting smoking or vaping, and cutting back on spicy, acidic, starchy or sugary foods. An antihistamine may help if allergies are the cause. It says to see a dentist if itching and other symptoms last about three days without improvement. The article dates from 2017, so check with your dentist.
What does a gum infection feel like?
Healthline says a gum abscess causes persistent, severe pain with swelling and redness, sensitivity to hot or cold, pain when chewing, a loose tooth, pus, a bad taste and sometimes fever, and that it will not completely heal on its own. Gingivitis is usually painless. See our guide on how to treat a gum infection.
Why does my gum hurt?
Pain in one spot may be an abscess, gum disease, trapped food or an injury, and Cleveland Clinic says a partly erupted wisdom tooth can cause pericoronitis with swollen, red gums and pus. Healthline's cut-on-gums article lists falls, sports injuries and sharp objects, improper flossing, hard-bristled toothbrushes and toothpicks as causes of cuts.
How long does a cut gum take to heal?
Healthline says a minor gum cut typically heals in about three to four days, and longer if it needs stitches or becomes infected. Apply a clean cloth for five to 10 minutes to stop bleeding, rinse with salt water, eat soft foods and avoid hot, spicy or citrus foods. Seek care if the cut is not improving in a couple of days or shows signs of infection.
When to see a dentist
Itching or pain that persists, a lump, pus or swelling, and a cut that does not improve all need a dentist, and fever or facial swelling needs urgent care. Our guide on bleeding and swollen gums explains what the dentist will check.
Preventing gum problems
Brush twice a day with a soft brush, clean between the teeth daily, avoid tobacco and keep up regular dental visits. Healthline says to brush and floss regularly and avoid irritants for itchy gums, and Cleveland Clinic says gingivitis is reversible when treated early.
Gum pain with dentures, braces or a new tooth
Healthline lists ill-fitting dentures or partials among the causes of itchy gums because gaps trap food and bacteria, and Cleveland Clinic lists plaque around braces and dentures that do not fit well as causes of swollen gums. If your appliance rubs, if pain appears soon after a new filling or crown, or if a wisdom tooth is coming through, tell your dentist rather than waiting. Adjustments to the fit, a cleaning or treatment of the flap over a tooth often settle the problem, and cleaning carefully around the appliance meanwhile limits plaque.
Home care that is safe, and what to skip
Rinsing with warm salt water, cleaning gently, eating soft foods and avoiding tobacco, alcohol and spicy or acidic foods are the home measures named by Healthline. None of them replaces treatment for an abscess, which Healthline says cannot be treated at home. Avoid putting aspirin or other tablets against the gum, cutting or lancing a lump yourself, or using strong rinses, and see a dentist instead.

- Do I have gum disease, and how advanced is it?
