Major problem.Dentist shaved teeth for caps wrongly and they protrude a lot. (overjet)?

I mean there is not much you can do at this point without seeing a new cosmetic dentist and requesting an extraction and replacement procedure, talk about $. It seems like your dentist followed the "standard procedure" for this operation. I would get advice or a second opinion if it feels awkward (this will probably be free or cheap for you to do) from any dentist nearby; any provable malpractice and you have a couple thousand $$$ lawsuit you can file my friend. Easy as that. Good luck!
