For those of us with "soft" teeth (and you know who you are), this is a REALLY *bad* development! I don't want to re-grow my teeth. In fact, I want to get rid of the originals! I would REALLY like to see advances in implant technology, and a reduction in price. I'd like to have all my teeth replaced. I've already had seven root canals, at least two crowns (with six more on the way) - why can't I just get them all replaced?
(As an aside, most dentists seem to want to "save" teeth. I can't see any reason for this. Furthermore, implants are expensive - to have my 28 teeth replaced at $4k/tooth would cost $112,000. If I had the money I would do it.)
