I have massively cracked two big molars. Hopefully they can be taken out tomorrow (they are beyond saving as they have totally cracked lenghtwise). I understand that my only option is to have implants and that I need to do this relatively quickly otherwise my jaw bone thins and I cannot have the implants. How quick do I need to have the implants? How can I find out if a dental clinic is reliable and knowledgeable as it is all non- NHS and I don't know how much oversight there is? Thanks.
