I was diagnosed with gum tumor during pregnancy when I went to the hospital. The doctor only prescribed mouthwash, but gradually the redness and swelling of the gum became bigger and bigger, and the bleeding became more serious. Can you give me a suggestion? I hope I can get an answer soon, thank you!　　Xu Li, Department of Periodontology, Peking University Stomatological Hospital: Hello! When gum tumor in pregnancy affects your quality of life, it can be surgically removed during the period of 4-6 months of pregnancy, and after the removal, you can apply gum plugging agent to stop the bleeding by pressure. However, you should pay attention to brushing your teeth.
