Swollen gums and tooth pain: what you can manage and when to get help

One swollen area versus widespread puffiness

Generalized redness and puffiness along several teeth commonly follow plaque accumulation. A single raised or tender area has a broader range of causes, including food trapped under the gum, a periodontal pocket, an erupting wisdom tooth or infection originating inside a tooth.

A pimple-like bump on the gum can be a drainage point from an infection even when pain temporarily improves. Drainage does not mean the source has healed.

• Swelling behind the last molar may involve tissue around a partially erupted wisdom tooth.
• Pain on biting can point to a cracked, inflamed or infected tooth.
• A bad taste, pus or throbbing increases concern for infection.
• Firm, painless or unexplained growths that remain for two weeks need examination.

Short-term swollen-gum relief

Brush the area carefully with a soft brush and remove accessible food from between teeth without digging into the gum. A warm salt-water rinse can soothe tissue and loosen debris, but it cannot clear an infection inside a tooth or beneath a deep gum pocket.

For pain, an over-the-counter analgesic may help if it is safe for you; follow the package directions and account for the same ingredient in combination medicines. Ask a pharmacist or clinician if you have ulcers, kidney or liver disease, take blood thinners, are pregnant or are unsure which option is appropriate.

• Use a cool compress outside the cheek for discomfort; do not apply extreme heat.
• Eat softer foods and chew on the other side temporarily.
• Keep brushing rather than allowing plaque to accumulate around the swollen tissue.
• Do not squeeze, puncture or attempt to drain a gum lump.
• Do not place aspirin against the gum because it can injure the tissue.

Natural relief has limits

Salt water is a comfort measure, not a cure for periodontitis or an abscess. Herbal oils and harsh homemade rinses can cause chemical burns, and their antimicrobial reputation does not establish that they can reach or eliminate the source of dental infection.

How dental treatment differs by cause

Plaque-related gingivitis is managed through effective home cleaning and removal of hardened deposits. Food impaction may require cleaning plus correction of an open contact, damaged filling or other feature that repeatedly traps material.

An infected tooth may require root canal treatment or extraction, while a periodontal abscess may need drainage and gum treatment. Antibiotics are not automatically required for every dental pain and generally do not remove the source on their own.

• A dentist may test the tooth, measure gum pockets and take an X-ray.
• Repeated wisdom-tooth inflammation may require cleaning, monitoring or extraction planning.
• Medication-related gum overgrowth should be discussed with both the dentist and prescriber.
• Never stop or switch a prescribed medicine solely because the gums appear enlarged.

Signs that swelling is urgent

Call a dentist promptly for localized swelling with tooth pain, pus, a foul taste, fever or increasing tenderness. Same-day assessment is particularly important when symptoms are progressing or the person has a weakened immune system.

Go to an emergency department or call emergency services if swelling interferes with breathing or swallowing, spreads into the face, neck or area around the eye, or is accompanied by severe illness. These features can indicate a spreading infection that is not suitable for home treatment.

• Rapidly enlarging facial swelling
• Difficulty opening the mouth
• Drooling or inability to swallow fluids
• Breathing difficulty or voice changes
• Fever with worsening facial or neck swelling
