Hi, i posted this question before but got contradicting answers which worried me even more so I was wondering if it's possible to get HIV from a dentist visit. Yesterday i went for a regular check up to the dentist i always go to because he's supposed to be the best in the city and I ended up coming back with an irrational fear of contracting hiv. All he did was polish my teeth and when i got home my gums were sensitive so they were bleeding a little bit which caused me to get worried and wonder if the equipment he used was clean or not! Usually they open a new packet of metal tools but yesterday i forgot to pay attention and check whether he opened them right before he put them in my mouth. Lets suppose he used the previous patients tools on my mouth, is there any chance of hiv infection from that? Especially because i also bled from my gums and what if there was blood on them from the previous patient? I have read that one dentist deliberately injected his patient with hiv blood so is injection the only way you can get hiv from a dentist or can the equipment and other cleaning tools also carry hiv infection? Many thanks!
