Is there any documented case of transmission of HIV through sharing a tooth brush?, or is this only considered as a theoretical risk?
Response from Dr. Reznik
I am unaware of any documented cases of transmission of HIV due to sharing a toothbrush. The risk, which would be exceptionally minimal, would be due to the fact that many people have gingivitis, which involves bleeding gingival tissues (gums). We do know that HIV is transmitted via blood and blood products, hence the warning not to share toothbrushes. Hygienically this makes sense as well....
