facial swelling emergency symptoms NHS anaphylaxis dental infection
Facial swelling can have several causes. Common ones include:
- Allergy: sudden swelling of lips, eyelids, or face, often with itching, hives, or after a food, medicine, insect sting, or cosmetic product.
- Dental infection/abscess: toothache, gum pain, bad taste, fever, or swelling of the jaw/cheek. It needs urgent dental treatment and will not resolve on its own.
- Skin or sinus infection: redness, warmth, pain, fever, or swelling around the eye/nose.
- Salivary-gland blockage/infection: painful swelling near the cheek or below the jaw, sometimes worse during meals.
- Injury: swelling after a fall, hit, dental procedure, or surgery.
- Fluid retention or kidney/thyroid issues: usually puffiness around both eyes, often worse in the morning.
Get emergency help now if swelling is sudden and involves the lips, tongue, mouth, or throat, or there is trouble breathing, swallowing, speaking, dizziness/fainting, or wheezing. These can indicate anaphylaxis, as described by the NHS anaphylaxis guidance.
Seek same-day dental or medical care if you have fever, worsening one-sided facial swelling, severe tooth pain, difficulty opening your mouth, swelling around an eye, vision changes, or difficulty swallowing. A dental abscess can spread and needs prompt treatment.
Until assessed: use a cold compress, keep your head elevated, avoid squeezing the area or applying heat, and follow labeled doses of usual pain medicine if safe for you. Do not start leftover antibiotics.
