How to keep bur perpendicular to long axis of tooth

I understand the concept of keeping the bur perpendicular to the long axis of the tooth, but I am having trouble knowing how to line my bur up on the occlusal surface and being able to know it's at the right angle. Do you have any tips on how you know it is in the right position?

check it from different angles with the mirror.

An amazing tip my professor gave me was to drop the bur to fit between the proximal contact where the embrasure is (I drew an example of what I mean). As long as it’s parallel to that, it should be parallel to the tooth as well : ) Hope that helps!!
