I am considering doing a implant on a front tooth, my dentist said there is a chance gum might shrink after the implant and look ugly between the two front tooth. should I be concerned about that, is that a big chance for that to happen? also should i do a zirconia implant as oppose to a titaniam implant for best result cosmetically? where do I find a good implant dentist around LA area? my dentist says it will cost me $4000 plus to do a implant, but I also see advertising for $2000 or $1000
