Q. In a weeks time I am having the first stage of two implants being put in, on my top jaw near the front, after two extractions and a bone graft last june. I will have a bridge as well as I now have three spaces. When I was given a quote in June, the dentist said it was very unlikely I would need to have two ‘exposures’ but now he says I do have to, costing an additional £165 each, or otherwise I can not wear my denture for the next six months. I simply could not understand his explanation. Could you please explain? Thank you.,
