What should you do after noticing a purple swollen gum?
Biting, hard food, dental appliances, erupting teeth, gum infection, or a blood-filled blister can alter the colour. A swelling beside a painful tooth may indicate an abscess, while medication or general health factors can affect bruising.
When does a purple swollen gum need prompt care?
Avoid biting or rubbing the area, brush gently, and photograph the change so you can track it. Do not puncture a blister or apply caustic substances.
