A patient has to undergo surgery to get dental implants, which requires the use of anesthesia. So in order to get dental implants, you need to have an overall clean bill of health that your general physician signs off on. Moreover, you also need to have healthy gum tissue to qualify for dental implants. Those with periodontal disease or other gum issues cannot get dental implants since the chances of successful surgery are extremely low. Some people also suffer from bone loss in the jaw when they lose their teeth. In such cases it can be difficult to conduct successful dental implant surgery. Fortunately, your prosthodontist will recommend you get bone grafting to get your jaw back into shape for dental implant surgery.
