I had 2 teeth extracted behind my canine tooth in my lower jaw.Its been a few years so the teeth have shifted.Theres only room for one implant, and a small gap will remain,so I did it.I expected the dentist to put the implant closer to the canine,but he put it in the center of the gap.I specifically told him I want to fill in the space near the canine tooth.I asked him about it and he said it's fine.I'm worried because he can't put a big tooth there because it won't look good.What could be done?
