Most dental implant procedures begin in a similar fashion, regardless of the number of teeth being replaced: a preliminary exam and molding. To receive dental implant services, you must have healthy gums and surrounding teeth. Those with active periodontal disease are not good candidates for dental implant treatment, as the implants themselves are anchored by the jawbone and gums. Your dentist will determine if your gums and jaw are in good health, then he or she will take an impression of your teeth so the replacement tooth can be custom-made for your mouth.
