Painless Dentistry?

I've been genetically blessed with few but good teeth. Those less fortunate may want to look into this for the treatment of cavities :

The method, popular in Australia and Japan, uses a special disinfectant, activated by laser, to kill instead of drill out the bacteria.
The tooth can then rebuild itself aided by a porous sealant and a tooth mousse, which is used at home and promotes tooth growth.

It looks like a lengthy, expensive process as of now, but it might be worthwhile for those who are extremely averse to dental drilling. Whether this procedure succeeds in the marketplace will, of course depend on our trade-offs between pain (and drill) avoidance in comparison with other uses of our money. In the future, look for continuing technological change to make it less expensive.
