Raw after mouth surgery??

I don't know if I should post this in Nutrition or Health - so I'm doing both.  I hope that's okay. 
 
Question - Does anyone have an opinion on feeding raw while the dog has stitches in the mouth? 
 
Slick had surgery in the mouth yesterday and has stitches in his cheek.  He is not meant to do any crunching or chewing so his raw medallions are perfect in terms of consistency.  My concern however, is that I may be exposing the surgery site to harmful bacteria?   ALL opinions welcome!!
