Hi all doctors will use only clean instruments.HIV cannot live in the external atmosphere for more than maximum 1min. The virus dies immediately after it's exposed to external environment. This is just for your knowledge.

Hi. Usually every clinician autoclaves his/her instruments once used. But if you knew that a used instrument was being used on you, you could have stopped him/her. On the other hand the dentist might have changed the instruments and you might not have noticed (the basic instruments look alike). Regarding HIV/AIDS. it is possible to acquire Hiv through used instruments. But for that to happen, the patient prior to you should have that infection.. hiv won't magically appear out of thin air. Hiv is not the ot infection that you need to be concerned about. There are host of other communicable diseases that you can get.

Yes HIV can be transmitted by dentist tools. But nowadays none of the responsible dentist would use any unsterilised tool on anyone. But still if you have any doubt you can ask your dentist to disclose his/her sterilization procedure for instruments used and the dentist will be happy to explain his/her procedure as it is your right to know about it. It is really appreciated that you are aware of all the things. The best way to get your worries resolved is to have a HIV test. You can have it done at your nearest hospital and the test is confidential so your name will not be disclosed to anyone. There are also home kits available for the test but I suggest you to go for lab results.
