A dental drill is a small, dental high speed handpiece used in dentistry to remove decayed tooth material prior to the insertion of a dental filling. Dental drills are used in the treatment of dental caries. The term "dental drill" is considered the more colloquial form of the term "dental handpieces," although it can also be construed as to include the power source for one or more handpieces, a "dental engine." "Handpiece" and "engine" are more generic and euphemistic terms for generic dental tools. We provide dental handpieces including dental high speed handpiece, dental optic handpiece, dental low speed handpiece and dental handpiece accessory.
