Gum bleeds when i brush
Gums that bleed during brushing are often inflamed by plaque, although trauma, gum disease, or another health issue can also contribute.
The short answer
Plaque is a bacterial film along the gum margin. Inflammation makes the gingival tissue swollen and more likely to bleed when a brush or interdental cleaner touches it.
How should you brush and clean between teeth gently?
Continue gentle brushing twice daily with a soft brush and clean between teeth carefully. Do not scrub harder or stop cleaning the area, and arrange a professional cleaning if deposits cannot be removed at home.
When should persistent bleeding be assessed by a dentist?
See a dentist if bleeding persists, gums swell or recede, teeth feel loose, bad breath continues, or you take medicines that affect bleeding. Heavy bleeding, facial swelling, or fever needs prompt care.
Could plaque, calculus, pockets, or a filling be responsible?
Could plaque, calculus, gum pockets, or a rough filling be causing this? Do I need periodontal measurements, cleaning, or a review of my brushing technique?
Frequently asked questions
Can a new toothbrush cause bleeding?
A hard brush or forceful technique can injure gums, but ongoing bleeding should not be attributed to the brush without an examination.
When should I arrange an examination?
Arrange an examination when symptoms persist, worsen, or interfere with eating, sleeping, cleaning, or normal function.
