why do my gums bleed when I brush my teeth?

Have you ever noticed your gums bleeding whilst you brush your teeth? Perhaps they look redder than usual or feel swollen and sensitive? If you’re worried about why this is happening, the common causes of bleeding or sensitive gums include:

  • Poor oral hygiene
  • Using a toothbrush which is too hard
  • Being too rough when using dental floss
  • Taking certain medicines such as Aspirin or Ibuprofen
  • Early-stage gum disease or gingivitis

Bleeding gums and gum disease

Bleeding gums are most commonly caused by a build of plaque and tartar that allows bacteria to grow under and around the gum line. Whilst treatable in its infant stages, a large build-up of bacteria may lead to gum disease, or periodontitis, if not addressed.

Gum disease is the leading cause of tooth loss in adults which is why our professionals advocate a preventative approach to oral hygiene. This helps to reduce the risk of developing a severe oral health issue over time.
