Pocket tens post flop.

Hey guys,
I am holding pocket tens. I raise 4x BB. 2 reasonably aggressive players come along for the ride.
The flop comes 9c 9s 2h.
Seeing as my poocket tens are an overpair to the flop, what is the probability I have the best hand at this point. e.g. no one has overpairs to me, a nine or pocket twos.

my situation was fairly desperate (should have probably moved all in with pocket tens but felt i needed a caller)
After flop I was second to act, first guy checked, If i was going to make a move it had to be all in, so I did. I then fell to the man on my left who had A 9.
Was I justified in my actions?
Any math or reply is greatly appreciated.
