Bleeding from brushing occurs due to inflammation of the gums. Gingivitis is formed when there is plaque and calculus that irritate the gums. The main symptoms of gingivitis include bleeding gums, gum recession, and red and swollen gums. Once you find out that your gums are bleeding, you must pay attention to it. Don’t refrain from brushing your teeth because you are afraid, which is very dangerous. Bleeding gums are often caused by gingivitis or periodontitis, and you should go to the hospital as soon as possible for periodontal treatment, which uses ultrasonic shock to remove calculus, plaque, and other irritants around the teeth. Then alternate local rinses with 3% hydrogen peroxide and saline, and then apply iodine glycerin or Pario locally to decongest the gums and periodontal tissues, then rinse with mouthwash to consolidate the treatment, maintain the oral flora environment, and keep the oral hygiene. In the case of gingivitis, the gingivitis can be cured with thorough treatment, and in the case of periodontitis, the periodontitis can be stilled and not further developed. Bleeding from brushing is a typical sign of gum inflammation, and it is important to get treatment for this symptom as soon as possible, otherwise, gingivitis will continue to destroy periodontal tissues and form inflammation of the periodontium. Periodontitis is very scary, it is the most important cause of tooth loss, so for gingivitis or periodontitis, it is important to do early diagnosis and early treatment.
