Why are my gums sensitive when i brush
Sensitive gums during brushing often reflect inflammation, brushing trauma, recession, or another condition that needs an examination.
The short answer
Gingival sensitivity is discomfort in the gum tissue during brushing or contact. Inflamed gums can look red or swollen and may bleed because plaque irritates the tissue at the gum margin.

What is the direct answer?
What does this question mean?
A hard brush, forceful scrubbing, a rough filling, exposed root surface, mouth ulcer, or gum recession can add local irritation. Bleeding is not a reason to stop cleaning because retained plaque can maintain inflammation.
What can you do next?
Use a soft toothbrush with gentle small movements at the gumline and clean between teeth daily. Do not use very hot water or abrasive powders on tender tissue; arrange a professional cleaning if deposits are present.
When should you seek dental care?
See a dentist if bleeding lasts, one area is persistently painful, gums recede, teeth loosen, or swelling and bad taste develop. Fever or facial swelling needs urgent care.
What should you ask the dentist?
Ask whether the issue is gingivitis, recession, a traumatic brushing method, decay, or a restoration. Ask for a brushing demonstration and an interdental cleaning recommendation.
