Is vancomycin commonly used after revision facial implants?

I am looking to revise my facial implants due to past infections resulting in me losing some of them. ive been told next time i will be put on vancomycin for a long period post surgery. id like to know if this is commonly used and does it work in preventing infection? also how important is the use of mouth wash after facial implants? and how soon should oral hygeine start after surgery? can the lack of mouthwash cause infection too?
