I never had a problem with Trakanon's Teeth prior to a patch in February 2013.
Since that patch I haven't been able to use TT properly.
The symptoms I experience after zoning into TT are:
Latency appears normal (250ish), I try to use an item like Jboots to see whether I'm desynching, if I am they don't work and my ping slowly starts to rise by around 1000 every minute or so until it reaches 8-9000 then I get disconnected (this usually allows me enough time to run to seb orb and /q). Sometimes however I use my Jboots and they work immediately and my ping goes up to around 1000 then stabilises and starts to come back down. This happens around 1 in 20 times I zone in to TT.
The patch I am referring to that broke TT for me was one of the following.
It was either v26:

or v27:

Unfortunately they were only 1 day apart so I don't know which of the 2 it was, but looking at the size of the 2 patches I would assume it was v26.
Other people were experiencing the issue prior to this however so I'm not sure how helpful this information will be.
