Hi! Welcome to Healthcaremagic. I read your query. Minor bleeding from gums while cleaning teeth can occur sometimes. However, if you are having regular bleeding problem, it can be due to various reasons. If its due to local gum disease, after cleaning maintain good hygiene. Use soft toothbrush with a toothpaste containing tannic acid. Do warm saline rinses, gum massage. Take vitamin c, healthy diet including citrus fruits, carrot, spinach, etc. Bleeding should stop in 2-3weeks. If it persists, go for further investigations like blood test for anemia, clotting factors, diabetes, etc. Genetics can also be a reason. Hope the answer helps you. Thank you.
