Ok, thank you, I appreciate your answers.
1. How long did it take you to find that?
2. Finding that clearly shows anxiety is at high and you need to get control of it
3. It says nothing about HIV. So no there is not a risk just as I wrote.
The article you reference makes no mention of HIV - that is because HIV cannot be transmitted that way. If you have other questions about the safety of using dental equipment, we suggest visiting the Dental Health forum, as this forum is HIV specific.
According to this there is a risk: http://www.dimensionsofdentalhygiene.com/2010/02_February/Departments/Tips_on_Technique.aspx
Suggest you speak to a therapist as this has nothing to do with HIV.
