Gums that bleed during brushing are common, but persistent bleeding should not be ignored. Plaque-related inflammation is a frequent cause, although medicines, hormonal changes, brushing trauma and certain health conditions can also contribute.
Gingivitis and periodontitis
Gingivitis affects the gum margin and may cause redness, swelling and bleeding. It can often improve with professional cleaning and effective daily plaque control. Periodontitis involves loss of the supporting tissues and bone around teeth. It requires ongoing professional management and can progress without dramatic pain.
Signs that deserve assessment
Book a dental visit for persistent bleeding, bad breath, gum recession, loose or shifting teeth, pus, pain on chewing or changes in the way teeth meet. Sudden unexplained bleeding elsewhere in the body or severe symptoms should also be discussed with a physician.
What does gum assessment involve?
The dentist may measure the space around each tooth, check bleeding, mobility and recession, and use X-rays to assess bone levels. Treatment can include oral-hygiene instruction, professional cleaning above and below the gumline, management of risk factors and scheduled maintenance. Advanced cases may need referral to a periodontist.
Daily care matters
Brush gently twice daily with fluoride toothpaste and clean between teeth using a method suited to the spaces. Do not stop brushing because the gums bleed; instead, seek guidance and improve plaque removal without aggressive scrubbing.
