Red sensitive gums
Red, sensitive gums often reflect inflammation, but recession, brushing trauma, ulcers, new products, or periodontal disease can also be responsible.
The short answer
Red, sensitive gums most often reflect inflammation at the gum margin, but recession, brushing trauma, ulcers, a new product, or periodontal disease can produce similar discomfort.

What is the direct answer?
What does this question mean?
Healthy gingiva fits closely around the teeth and can become red, puffy, tender, or prone to bleeding when plaque remains at the margin. Sensitivity may also expose root dentin, where open tubules transmit cold and touch toward the pulp.
What can you do next?
Use a soft brush and light pressure, clean the gumline and between teeth, and pause irritating whitening or strongly flavored products. A dentist can remove calculus, check for recession and cavities, and recommend a desensitizing toothpaste or periodontal care suited to the findings.
When should you seek dental care?
Arrange care if redness lasts, sensitivity is localized to one tooth, gums recede, a tooth loosens, or there is pus, swelling, ulceration, or persistent bad breath. Urgent assessment is needed for rapidly spreading swelling or severe pain with fever.
What should you ask the dentist?
Ask whether the tissue shows gingivitis, periodontitis, recession, abrasion, a root cavity, or an allergic reaction. Ask how the gumline will be cleaned, whether bite forces or restorations contribute, and which home-care technique protects the exposed surface.
Frequently asked questions
Why do my gums hurt when I brush?
Inflamed tissue, exposed roots, ulcers, or excessive pressure can hurt; gentle cleaning and an examination help separate these causes.
Can sensitive gums heal?
Inflammation from plaque or an irritant may improve when the cause is controlled, while recession and cavities need specific treatment.
