Gum problem guide
6 min readSwollen gums
Swollen gums may be local or more general. Spreading swelling, facial swelling, fever or difficulty opening the mouth needs urgent advice.
Gum swelling can appear around one tooth, between teeth or across a wider area. It may be sore, bleed, feel soft or firm, or be linked with a bad taste.
A swollen gum is not the same as spreading facial swelling, but dental infection can sometimes spread. Worsening or spreading swelling needs prompt assessment.
