Here I fight and defeat Dark Tooth fair and square, using Warthog.
The best way to beat Dark Tooth is to simply wait for him. When he comes around a corner, freeze and fire, then run for it. Collect any weapons along the way. The best places to wait are under the subway tracks (that way, his blasted head won't touch you) and near the Temple. Under the subway tracks, Dark Tooth may jump over it, thus giving you lots of time to escape. Near the temple, as long as you don't stay in it you should be able to switch to a different area.
The fastest way to kill Dark Tooth is by detonating 10 remote bombs on him. Put on your shield, then spam the trigger for the Remote icons. The reason why this works is because you'll be under DT when the remote bombs launch you both into the air, and when you "plant" a Remote Bomb it will be planted into DT thus causing him to detonate it prematurely. This method turns a 6 min fight into a 30-second one. I don't do that method (since I start the DT fight fresh via password), but I do know that Remotes are a potent weapon against DT.
