Gum red and sore
Red, sore gums commonly reflect plaque irritation, but persistent swelling, bleeding, or pain needs an examination for the cause.
The short answer
Red, sore gums are often caused by plaque irritating the gingiva, but infection, trauma, ulcers, or another condition can also be responsible.

What does it mean when the gum tissue is inflamed?
The gingiva is the soft tissue that surrounds and seals the teeth. Redness means the tissue is inflamed; soreness may come from bacterial plaque, a sharp food fragment, vigorous brushing, a new appliance, or a local ulcer.
What can I do for red and sore gums today?
Brush gently along the gumline with a soft toothbrush, clean between the teeth, and rinse with warm salt water if it is comfortable. Avoid tobacco, very spicy foods, and picking at the area, and arrange an examination if the irritation does not settle.
When do red and sore gums need dental care?
Book dental care for bleeding with brushing, repeated swelling, bad taste, loose teeth, or symptoms that persist. Seek urgent help for facial swelling, fever, difficulty swallowing, or difficulty breathing.
What should I ask about red and sore gums?
Ask whether the inflammation is limited to the gingiva or has affected deeper supporting tissues, whether a professional cleaning is needed, and how to clean the specific area without injuring it.
Frequently asked questions
Can sore gums heal after better cleaning?
Mild plaque-related inflammation may improve with consistent gentle brushing and interdental cleaning, but persistent symptoms need assessment.
Why do my gums bleed when I brush?
Bleeding can occur when inflamed gingiva is touched, although trauma and other causes are also possible.
