Is there really a place known as the "best spot for snaggletooth correction"?

I've been looking for a great place for snaggletooth correction, and while there are lots of before-and-after photos, the criteria are a bit vague.

I'm worried that if my snaggletooth is severe, the treatment period will be longer and I might experience more pain.

Do they tell you the treatment plan or the estimated duration right away during the consultation?

Besides reviews, what else should I look for to be safe when choosing a clinic for snaggletooth correction? Haha.
