I don't often look in his mouth and wouldn't probably be sure, but I was told the first time I had him floated he still has his wolf teeth.
We discussed it and since he's never had trouble, they stay. I use only snaffle mouthpieces on him.
Sounds like you are right to just leave them alone.
The bit I use on him is a broken bit, but it has a port that is hinged on both sides, or, I sometimes rotate him in to a long shank snaffle, and if I'm feeling really brave:) my argentine snaffle. I try to change every so often. I've been told it keeps them sharper, paying attention better.
