I am 18 years male currently live in China. I always go to this dental clinic, which was really expensive, about couple thousand RMB just for a routine check up. I'm just wondering, I always went with my family, they usually had one doctor there. I never saw them changing the equipments, brush etc. I am not sure do they sanitize the equipments. Am i at risk? Like i said, they are really expensive and i don't think they would not sanitize their equipments.
