A good candidate for dental implants is anyone missing one or more teeth, or who is unhappy with their dentures. Age is not a factor. However, smoking, diseases such as diabetes, and radiation therapy to the area, have been shown to lower the success rate of implant placement. X-rays of your jaw will be taken to evaluate whether they will accommodate implants. Cone beam scans may also be required to determine if other tests or procedures are needed to place implants properly.
