Please stop worrying about all of this. The risk from your dentist is not low. It is zero. From your posting your dentist did not have a bleeding wound on his face (and, in addition, you have no knowledge if he is even HIV positive).
Your test came back as negative because you do not have the virus. You can relax. No further testing is needed. You are HIV negative.
(Sigh)...well, we're on our 118th reply to a non-exposure and you still don't seem to be able to accept the fact that you are HIV negative.
So what the heck, continuing testing from now until "the cows come home" (as my dad used to say) if it makes you feel better.
The results won't change one bit. Once again, you were never at risk to begin with since your sexual contact was protected. ALL your testing (and yes, ALL) have come back with negative results.
You'd likely do better with some professional therapy to help you understand why you can't accept what should be good news that you are HIV negative instead of spending yet more money on useless testing.
And so, no there is absolutely no possibility that your result will change from this test.
Of course the test will be negative....because nothing happened. No one jabbed you with an HIV containing needle.
And yes, if it were me, I would not worry one second over this matter. But then, I do not have OCD over such things.
Note...while there is NO medical need to get tested because there was absolutely not risk here perhaps getting that nice, big negative test result will help you put all these concerns behind you. If so, then get tested just once. Believe the negative results and promise yourself you will then move on from all of this, OK?
Because all of these physicians trust these test results (as we do) and because (as I've posted many, many times before) your sexual contact with this person was protected.
You never were at risk for HIV in the first place.
Testing has clearly and without question shown you are HIV negative.
For some unfathomable reason you have difficulty accepting what should be very good news regarding a negative HIV status.
Instead, you continue to worry over symptoms that you believe must be connected to HIV despite ALL test results showing a negative status.
I don't believe this forum (or others) can state it any clearer that you are HIV negative and that you can continue to test for months and months down the road and the results will not be any different.
It is time to put all these worries behind you and get on with your life.
I suspect once you do that many of your "symptoms" will suddenly improve.
