Hi..
A dental implant is an artificial substitute/replacement for the root portion of your natural tooth and is anchored into a pre-drilled socket in your jaw-bone to support a crown, bridge or secure a denture firmly in place.you go to someone who is well qualified then the chances are that you won't have any problems. Don't just go for the cheapest quote.The metal part of the implant should not show as the prosthetic tooth should be screwed into it and cover it up completely so that it looks like a normal tooth. If you don't have enough bone in your gums then a bone graft can be done. Not enough bone can be a reason why an implant will fail as they are supposed to integrate with the bone and if there is not enough it will not be 'strong' enough. Again if you go to someone good, the chances that it will fail are reduced.
