Swollen gum hurts
A painful swollen gum can result from plaque, trapped food, trauma, decay, or an abscess, so the cause determines treatment.
The short answer
A painful swollen gum can result from plaque, trapped food, trauma, decay, or an abscess, so the cause determines treatment. Rinsing may ease irritation, but it cannot remove a deep infection or calculus.
Why does inflamed gum become tender and puffy?
Inflamed gingiva becomes red, puffy, tender, and more likely to bleed. Swelling beside one tooth is more suggestive of a local problem such as trapped debris, a periodontal pocket, cracked tooth, or root infection.
What can you do for a painful swollen gum now?
Brush gently with a soft brush, clean carefully between the teeth, and rinse with warm water. Do not lance the swelling or place caustic substances on the gum; arrange examination if it does not settle quickly.
When does painful gum swelling need prompt care?
Seek prompt care for persistent pain, pus, a bad taste, fever, or swelling near a tooth. Emergency assessment is needed for spreading facial swelling or difficulty breathing or swallowing.
What should the dentist check when gum swelling hurts?
Ask whether the swelling comes from the gum, tooth pulp, or a wisdom tooth and whether imaging is needed. Ask which treatment removes the cause and how to prevent recurrence.
Frequently asked questions
Can salt water cure a swollen gum?
A mild rinse may soothe tissue, but it does not treat calculus, decay, or a dental abscess.
Why is the swelling beside only one tooth?
A local pocket, trapped food, cracked tooth, or root infection may be affecting that area.
