There are several possible causes of bleeding while brushing teeth. The following are some common reasons:
1. Improper brushing techniques: Using a toothbrush of poor quality or brushing too aggressively may damage the blood vessels in the gums, causing bleeding.
2. Nutritional deficiencies: A lack of vitamins C and K, which help maintain healthy gums.
3. Gingivitis: Gingivitis is a common cause of bleeding while brushing teeth. The gum tissue becomes congested and swollen, with superficial capillaries that are prone to rupture from even minor irritation, resulting in bleeding.
4. Dental calculus: Poor oral hygiene over time can lead to the formation of dental calculus (tartar). The edges of calculus are rough and contain various bacteria, which can irritate the gums, causing redness, swelling, inflammation, and bleeding.
5. Dental caries: When cavities form on the tooth surface, brushing may cause bleeding when the cavity is touched. The affected tooth may appear dark or black and is usually accompanied by pain.
If bleeding occurs frequently during brushing, it is recommended to consult a dentist for examination to determine the exact cause and take appropriate measures.
