Yes, tar builds up in the leaves as you smoke a cigar.

I have seen photos and read of instances of the tar-build up at the head of some cigars being extreme, but I have never experienced any that I couldn't deal with.
I nearly always use a v-cutter for all but torpedos, etc. and I have noticed on some of the heavy bodied cigars a build-up of tar on the "lips" of the v-notch. I think that is a point of condensation where the vaporized tar meets a cooler medium.

I guess that's better than it building up on your teeth.
