Death knell for the dentist's drill?

With the possible exception of those singing, mounted fish, there is likely no piece of technology quite so universally hated as the dental drill.

When it comes to the treatment of cavities, the current approach is to treat small ones with fluoride therapy, then wait for anything larger to reach the stage where it needs to be drilled. Now, dental technology company DMG is offering a cavity infiltration system called Icon, that allows dentists to treat no-longer-small cavities before drilling becomes necessary.
