Hello! The patient suffered from massive bleeding after oral plastic surgery, mainly due to improper diet. It is suggested that patients eat more vegetables and fruits with high vitamin content at ordinary times, and insist on brushing their teeth in the morning and evening and gargling after meals to prevent dental calculus and plaque. In addition, you can also use some iron gold, white hair, selfheal and boxing ginseng to boil water to drink, which is very helpful for treating pain and stopping bleeding. I hope I can help you.
