Why is my gum around one tooth swollen
Swelling around one tooth can come from trapped plaque, a gum pocket, food injury, decay, or an infection near the root.
The short answer
A localized swelling is different from generalized gingivitis because one site may have a specific cause. The dentist checks the gum pocket, tooth surface, pulp response, bite, and surrounding bone, often with a dental radiograph.
What can cause swelling around just one tooth?
Rinse gently with warm water, brush the area softly, and clean between the teeth if you can do so without forcing an object into the gum. Do not squeeze the swelling or place aspirin on the tissue; arrange an examination to remove the cause.
What can you do for swelling around one tooth?
Seek urgent care for facial swelling, fever, difficulty swallowing or breathing, spreading redness, pus, or severe pain. A small recurring bump, tenderness on biting, or swelling lasting more than a brief irritation also needs assessment.
When does one swollen gum need urgent dental care?
Ask whether the swelling is in the gum or from the tooth root, whether a pocket or cavity is present, and whether an X-ray is needed. Ask what treatment will remove the cause and how to prevent recurrence.
