Deutsch, of the Washington Center for Dentistry in Washington, DC.
Here?s how it works: The dental decay finder touches the surface of every tooth, each time flashing a digital score that reports the presence of decay. A tooth that scores above a certain number?has at least the tiniest dot of decay.
And getting at the teeny offending area involves another technological wonder. A gentle dental ?sandblaster? uses tiny particles to whisk away decay in layers. The area gets filled in with a tooth-colored liquid that hardens in seconds under a special light.
Patients walk out of the office with tiny fillings.
?And the best part,? says Dr. Deutsch, ?is they have treatment with no needle and no drill!?.
