my son's teeth scraped inside his mouth (a small bleeding) 24 hours later we ate at a cafe. may he have gotten hcv virus? . my sons's upper front teeth scraped his mouth and caused a little bleeding. 24 hours later we ate at a cafe with the utensil of they bring. i am concerned about any invisible blood or saliva remaining on the fork. a few hours later the meal i remembered the situation and looked inside his mouth. the small wound was whitish and he says the place did not hurt during eating.
