Gum is red and swollen
Red, swollen gums usually indicate gum inflammation, but trapped food, trauma, infection, or another condition can also cause this change.
The short answer
Red, swollen gums usually reflect inflammation from plaque at the gum margin, but trapped food, trauma, infection, or a medical condition can also be involved.
What happens inside irritated gum tissue?
The gum tissue, or gingiva, becomes red when increased blood flow and immune activity accompany irritation. Swelling may affect one papilla between teeth or a larger area, and bleeding, tenderness, bad taste, or drainage can help identify the cause.
How can you clean swollen gums safely?
Brush gently along the gumline with a soft toothbrush, clean between the teeth with floss or an interdental brush, and rinse with water after food is trapped. Do not squeeze a swelling or place aspirin, alcohol, or concentrated chemicals on the gum.
When do red swollen gums need dental care?
Arrange dental care if swelling persists, recurs, bleeds readily, or is associated with tooth pain, pus, fever, facial swelling, or difficulty opening the mouth. Facial swelling that affects swallowing or breathing needs urgent medical attention.
What examination might identify the cause of swelling?
Ask which areas show plaque or calculus, whether a tooth or gum pocket is infected, and whether an examination, dental radiograph, professional cleaning, or periodontal treatment is needed.
Frequently asked questions
Can home care replace a dental examination?
Home care can reduce irritation or discomfort, but it cannot diagnose or remove an underlying dental cause.
What information should I bring to an appointment?
Bring a list of symptoms, their timing and triggers, medicines, allergies, and any recent dental treatment.
