Swollen gum and sensitive tooth
A swollen gum beside a sensitive tooth may reflect gum inflammation, exposed dentine, decay, a crack, or infection around the tooth.
The short answer
Gum swelling is enlarged gingival tissue; sensitivity is a response to cold, touch, sweet food, or air. They may be related or separate problems.
What is the direct answer?
What does this question mean?
Plaque inflames gums, while recession or enamel loss exposes dentine tubules that transmit fluid movement toward the pulp.
What can you do next?
Clean gently, avoid triggers, and do not press or drain the swelling. Desensitising toothpaste may help exposed dentine but does not treat decay or infection.
When should you seek dental care?
Arrange prompt care for persistent swelling, biting pain, lingering sensitivity, bad taste, pus, fever, or facial swelling.
What should you ask the dentist?
Ask whether the source is exposed dentine or pulp inflammation and whether an X-ray or pocket test is needed.
