Dentist Shaved off Too Much Tooth to Prepare for a Spring Retainer

I got spring retainers to move my teeth and the dentist shaved off too much of my lateral incisor #26. Even with the tooth in the correct position there is a huge gap between that tooth and the one next to it. It doesn't look too bad from the front but from the side it is horrible and I can feel the huge gap. I want this fixed and feel like this dentist should pay for it. What is the best/easiest way to fix this. Would bonding work? I do not want a crown if at all possible.
