Swelling around crown tooth
Swelling beside a crowned tooth can come from gum inflammation, food trapping, decay at the crown margin, or infection in the tooth or root.
What can cause swelling beside a crowned tooth?
Swelling beside a crowned tooth can come from gum inflammation, food trapping, decay at the crown margin, or infection in the tooth or root.
How can bacteria irritate the gum around a crown?
A crown covers the visible tooth, but bacteria can still irritate the gingiva at its edge or reach decay beneath it. Tenderness on biting, a gum boil, or deep throbbing pain can indicate inflammation around the root rather than a simple crown-edge problem.
What can I do when the gum around my crown swells?
Clean carefully around the crown with a toothbrush and interdental brush or floss, and avoid chewing hard foods on that side. A dentist may probe the gum, test the tooth, inspect the crown margin, and take an intraoral radiograph before choosing treatment.
When does swelling beside a crown need prompt care?
Arrange prompt care for persistent swelling, pain, a bad taste, or drainage. Seek urgent help if facial swelling spreads or causes difficulty swallowing, breathing, or opening the mouth.
What should I ask about swelling around my crown?
Ask whether the crown margin fits, whether decay or cement is trapping plaque, whether the pulp or root is infected, and whether the crown can be retained during treatment.
Frequently asked questions
Can this be diagnosed from the symptom alone?
No. Similar symptoms can come from different dental structures, so examination determines the cause.
What should I avoid while waiting?
Avoid practices that can injure the gum, tooth, denture, or restoration, and follow the practical steps described above.
