What should I do about my front tooth?? Had a tiny chip in it, was still very strong. Bonded it and it feels thin and weak.

I bit into a fork and put a tiny chip in my front top tooth. Of course, my dentist was away. I called a dentist I worked for as a teenager and he said he could bond it without drilling away any tooth. It looks beautiful, however, I have not eaten any real food or been able to relax because I feel that he did, in fact, drill away some of the enamel from the bottom of my tooth. It feels very thin. I am afraid my whole tooth will break...Sorry no photo
