When will drill-less dentistry become a reality?

Drill-less dentistry, also called air abrasion and microabrasion, is being offered by some dentists now. Air abrasion can be used to remove tooth decay, to remove some old composite restorations, to prepare a tooth surface for bonding or sealants, and to remove superficial stains and discolorations. The air abrasion instrument works like a mini sandblaster to spray away the decay, stain, or to prepare the tooth surface for bonding or sealant application. With air abrasion, a fine stream of particles is aimed at the tooth surface. These particles are made of silica, aluminum oxide, or a baking soda mixture and are propelled toward the tooth surface by compressed air or a gas that runs through the dental handpiece. Small particles of decay, stain, etc., on the tooth surface are removed as the stream of particles strikes them. The remnant particles are then "suctioned" away.
