Gums bleed when flossing mainly because of the following reasons:
- Plaque buildup along the gumline causes irritation and inflammation, leading to bleeding when flossed.
- Gingivitis, an early form of gum disease, causes swollen, tender gums that bleed easily.
- Improper or aggressive flossing technique can injure gums and cause bleeding.
- Infrequent flossing or newly starting to floss regularly can make gums bleed as they adjust.
- Vitamin deficiencies (especially vitamin C and K) or blood-thinning medications may increase bleeding tendency.
- More severe gum diseases like periodontitis cause inflammation that leads to bleeding gums.
- Bleeding may also result from soft tissue injuries or infected teeth affecting the gums.
It is generally normal to experience some bleeding initially when starting flossing, and it usually subsides within about a week if flossing is continued gently and regularly. However, frequent or heavy bleeding is a warning sign to visit a dentist for proper diagnosis and treatment, as it may indicate gum disease or other oral health issues. Proper flossing technique and consistent oral hygiene reduce bleeding over time and improve gum health.
