Bleeding between the gap of two teeth, what's the cause and how to deal with it?

Bleeding between two teeth may be caused by improper brushing techniques, oral ulcers, gingivitis, periodontitis, or the formation of periodontal pockets. It can be alleviated through daily care and medication. If physical discomfort occurs, it is recommended to seek medical attention promptly. The analysis is as follows:

1. Improper brushing: Using a toothbrush with hard bristles or incorrect brushing techniques may injure the gums and cause bleeding. It is advisable to use a soft-bristled toothbrush and brush gently, avoiding aggressive brushing or using unsuitable tools.

2. Oral ulcers: Oral ulcers are inflammations or lesions of the oral mucosa that may occur in the gum area between teeth. When ulcers develop, the gums may become sensitive and prone to bleeding. These ulcers are often triggered by fatigue, malnutrition, stress, or weakened immune function. It is recommended to brush regularly, clean interdental spaces with dental floss or interdental brushes, and use antibacterial mouthwash to reduce oral bacteria.

3. Gingivitis: Gingivitis is an inflammation of the gum tissue. The gums between two teeth may become inflamed due to bacterial infection, leading to bleeding. Maintaining good oral hygiene is essential—regular brushing and cleaning the areas between teeth with floss or interdental brushes are recommended. If necessary, medications such as amoxicillin capsules, cefixime dispersible tablets, or cefradine dispersible tablets may be used under medical guidance.

4. Periodontitis: Periodontitis is a serious oral condition involving infection and destruction of periodontal tissues, which may lead to gum bleeding. Professional deep cleaning and treatment should be sought, including scaling and possible periodontal surgery. In severe cases, medications such as minocycline hydrochloride capsules, tinidazole capsules, or paracetamol tablets may be prescribed.

5. Periodontal pocket formation: A pocket-like space forms between the gums and teeth, easily trapping food debris and bacteria, causing infection and bleeding. Dentists may recommend deep cleaning procedures, and in some cases, surgical intervention may be needed to repair periodontal pockets.

In daily life, it is recommended to consume adequate nutrients, especially foods rich in vitamin C, which help maintain healthy gums.
