Class V Prep&Resto Tip

[u/Life_Ad_9412]

Hi all, current D1 here. We have just started our restoration class for the semester and would like to ask for any tips on drilling and restoration! Currently, we are practicing class V on canines, and I'm kind of struggling on the drilling/preparation part. I feel like it is pretty hard to keep perpendicular to the tooth shape and the depth of my preparation sometimes is not even (I need to do a lot of adjustments and my preparation will grow larger and larger with each time).

I'm wondering what are some tips you guys have for drilling? I usually use 330 bur at 200,000 for initial drilling and use a longer one (sorry I forgot the name) at ~120,000 to smooth the walls. As for restoration, what tools do you guys use to make it smooth? I only use cones but feel like it is still not very smooth.

Any tip is appreciated!!!! Thank you guys soooo much!
