I had an implant done for about three teeth a couple years or eighteen months back. Pricey, but worth every penny of it.

They open the gum and surgically implant a threaded post (female) into your jawbone. About 8 weeks later you come back (sooner if problems develop!) and they screw a metal post with a male end into the first thing. Then you go to your regular dentist who puts a permanent bridge over the whole thing.

This cost me about USD 5,000; your prices will vary of course. Just be danged sure that the oral surgeon is fully qualified -- mine was a very experienced MD/DDS.
