Reasons for tooth brushing gum bleeding

Normal gums will not bleed when brushing teeth. If gums bleed when brushing teeth, it is usually caused by gingivitis or periodontitis. There are a lot of bacteria in the mouth. After eating in the mouth, there will be food residue on the hard tissue surface of the teeth and between the teeth and gums. If you do not brush your teeth well, rinse your mouth, use floss, and wash your teeth regularly, the bacteria and soft dirt remaining in the mouth will calcify into dental calculus. Dental calculus surface is very rough, will adhere to more bacteria and plaque. In the long-term effect of infection, gums and periodontal tissue will show inflammation, inflammation is one of the characteristics of chronic vascular expansion, at this time gum tissue will become congested, red, and more fragile, after a relatively weak external force, may cause gum tissue rupture, bleeding. In this case, the most effective way is to clean the hard tissue surface of the teeth and the calculus, plaque and bacteria between the teeth and gums, so that the inflammation of the gums and periodontal tissues can be reversed. After the gums are restored to health, there will be no more bleeding when brushing.
