When getting implants, there are many factors that can affect the cost. It can depend on: If additional bone grafting is needed, the number of implants, whether it is upper or lower or even both!, the number of appointments involved, whether the implants have a permanent bridge or a removable denture that attaches to them, etc... Every single one fo these factors can make a significant difference in cost. You ahve to remember, when you are wanting to get a complete replacement of teeth, it involves surgery and a great deal of precision in restoring them. You are essentially fabricating a complete new mouth to use for eating, chewing, talking, breathing, etc... As a dentist, we are replacing many years worth of issues and problems (usually) and it takes a gret deal of work. Not any dentist can restore this type of work. It takes on with advanced training in implant prosthodontics. I have seen cases which required a great deal of bone grafting and a complete permanent set of bridges, cost up to $100,000. And a single implant can be as low as $3500. The region of th ecountry or city you live in can also make a difference. Remeber, you are getting a permanent replacement of a tooth with an implant that is considered to be 98% of a natural tooth. There is no better alternative. If you are having questions regarding your dentists treatment, please get a second opinion. This style of dentistry is expensive initially, but the long term costs are very minimal for maintenance. A simle denture is another option for you but you get no benefits of impalnt retention.
