If this actually works as advertised, I hope it makes it to market as fast as possible. I'm pretty much done with the days of having new cavities, but I have composite fillings for all the cavities I did have, and ten years down the line they're starting to go bad. It's incredibly frustrating to have a dentist tell you you need to have an already-filled tooth re-drilled because the composite isn't sealing the cavity anymore and decay has set in around the edges where no amount of brushing could have prevented it. With any luck the current generation will be the last to suffer this fate.
