Swelling under eye tooth infection
Swelling below the eye can come from an upper tooth infection and needs prompt assessment, especially with pain, fever, or spreading facial swelling.
The short answer
Swelling below the eye can be related to an infection in an upper tooth, particularly a premolar or molar, and needs prompt dental assessment.
How can an infected tooth pulp cause an abscess?
An infected pulp can produce an abscess at the tooth root. Upper tooth roots lie near the cheek and tissues below the eye, so inflammation can spread into nearby soft tissue and change the shape of the face.
What should you do about swelling below the eye?
Contact an urgent dental service and do not press, puncture, or heat the swelling. Keep taking fluids, use a cool compress on the outside of the face, and use pain medicine only if it is suitable for you and taken as directed.
When is swelling below the eye an urgent problem?
Seek urgent care today for facial swelling linked with tooth pain, a bad taste, pus, or fever. Go to emergency medical care immediately if swelling affects the eye, vision, breathing, swallowing, or the ability to open the mouth.
Which tooth and tissues could be responsible?
Ask which tooth is responsible, whether the infection has reached the surrounding bone or soft tissue, and what imaging shows. Ask whether drainage, root canal treatment, or extraction is needed and how follow-up will confirm control of the infection.
Frequently asked questions
Can an upper tooth cause swelling under the eye?
Yes. The roots of upper teeth are close to facial spaces, and an untreated root infection can inflame nearby tissue.
Will antibiotics fix the infected tooth?
Antibiotics may be used when infection has spread or systemic symptoms are present, but they do not remove infected pulp; the tooth usually needs dental treatment as well.
