I've been told by multiple dentists I have a very unusual bite, though my teeth are in the alignment my bottom jaw looks a bit like a dogs. No kidding. I have an entirely flat bite (no curve whatsoever) with protruding lower canines. It creates a strange place to work with such a small mouthpiece. I've discovered that if I place my mouthpiece closer to one canine or the other my range, flexibility and accuracy improves. Any reason not to do this? I pointed it out to a fellow horn player once who when he actually looked at my teeth wondered how I got any sound. I think that essentially the curve in my lower teeth doesn't happen until a canine, whereas most folks have some curvature at the front? Anyone else experience this?

"If it works, it's correct." Sounds to me like you've found a solution.

I have pretty good teeth, so I've never had to deal with anything remotely close. But, here's my vague two cents:

1. Ergonomics. If it's damaging to your lips/teeth, don't do it.
2. Good sound. Keep in the back of your mind that changing your embouchure changes your sound.
3. Airflow. I think airflow is paramount. If you can still move a ton of air after switching up your embouchure, then you're okay by me.
4. Buzz. Mostly just need to build up your chops. This may take time.

As long as you can get a good buzz and lots of air through the horn, it's usually fine.
