I purchased a dental cleaning tool kit off amazon, it comes with medical grade dental cleaning tools. I don't have dental benefits and thought I could clean my teeth better with these.  Once I recieved the kit I used one of the tools to clean my teeth. They are sharpe tools that clean teeth/gum lines and it draws blood. The tools come with plastic protective removable pieces on the sharp ends. When I went to use another tool and removed the plastic piece, I could clearly see what was blood inside the end of the plastic peiece.  This was a kit that was clearly used, returned, not cleaned and resold. I have made a complaint with the seller. But I am now concerned I could have contracted a blood borne disease such as hepatitis b, hepatitis c and/or HIV. I'm almost certain I'm fully vaccinated against hep b, but will look into confirming this. I am now wondering if there was a risk of transmission and if I should be tested for hepatitis b, hepatitis c and HIV??
