Hi Dr Hughes. Could you tell me which method is better for teeth stripping, using a dental drill or having it done by hand with a diamond abrasive strip attached to a small piece of sheet metal? The same amount of enamel is to be stripped off my teeth, but I would like to know specifically which method will yield better results? I am trying to decide on an orthodontist to work on my teeth. I will be getting the Invisalign treatment. I look forward to your reply, thank you for your time.
