I have had to have an upper back tooth removed as the root filling they tried did not work. I cannot afford an implant but the dentist said he would not do a bridge which is covered on my dental plan. Can you explain why he is reluctant to do this? My Dad said he eventually pursuaded his dentist to do a Rochette bridge on similar tooth.How can I pursuade my dentist to do the same as I hate the gap I am left with!
