Maxillary swelling
Swelling in the upper jaw can come from an infected tooth, gum tissue, sinus disease, or another condition needing examination.
The short answer
Upper-jaw swelling is often caused by infection around a tooth or gum, but sinus disease, trauma, and other conditions can also contribute.
What is the direct answer?
What does this question mean?
The maxilla is the bone and surrounding soft tissue of the upper jaw. A tender lump beside a tooth may reflect a dental abscess, while swelling beneath the cheekbone can sometimes relate to the maxillary sinus.
What can you do next?
Rinse gently with warm water, keep brushing carefully, and avoid squeezing or puncturing the swelling. A dentist may examine the tooth, test its pulp, check the gums, and take dental radiographs to locate the source before drainage, root canal treatment, extraction, or other care.
When should you seek dental care?
Arrange prompt dental assessment for persistent, painful, or enlarging swelling. Seek urgent medical help if swelling affects breathing or swallowing, spreads toward the eye or neck, or comes with fever, confusion, or marked weakness.
What should you ask the dentist?
Ask which tooth or tissue is causing the swelling, whether imaging is needed, and whether the problem requires drainage, root canal treatment, extraction, gum care, or medical assessment. Also ask what warning signs should bring you back quickly.
