C172 pilot approaching runway 19 at teb reports a near midair collision with another C172 west bound...

Narrative:

Initially I was told to expect the teb ILS 19 approach and cleared to unvil intersection. I was approaching unvil at 2;000 MSL; still a few miles out; when ny approach asked me if I could see the airport; and when I said I could; I was cleared for the visual runway 19 approach. I turned right and headed straight for the numbers. The GPS indicated the magnetic bearing to teb was 170. Since it appeared I was already on glide slope; I started the descent; keeping the forward speed up at 120 KIAS during the initial approach in order not to be a burden to local traffic; which typically includes many corporate jets. I had descended to about 1;900 MSL when I noticed a plane to my left; at my 10 o'clock; that appeared to be at my height or maybe only a few feet higher; and I estimated that we were about 10 seconds away from impact. It looked like another cessna 172. I chose to push the nose over to get under the other plane fairly quickly; and I passed about 200 ft underneath it as it went over me left to right. At that moment teterboro tower called me to say I had traffic at 9 o'clock; I believe they said a mile; proceeding westbound; to which I responded that I had already seen it and dove and that the traffic was now 200 ft directly over me. Teterboro tower said the other aircraft was not talking to them. That was that. I did not observe the other aircraft making any maneuver; so I assume it never saw me. I proceeded to land normally.
