Dental drill is a term used to describe a device used by dentists to remove decayed parts of a tooth or shape it for a filling or crown. There are several synonyms for the dental drill including dental handpiece, dental turbine, dental bur, and high-speed handpiece. The dental handpiece is commonly used to perform restorative procedures such as filling cavities or removing old fillings. Dental turbines are air-driven handpieces that are used in restorative dentistry to help dentists prepare teeth for fillings or to polish restored teeth. On the other hand, dental burs are small, metal cutting instruments used to grind or etch the surface of teeth. These terms are often used interchangeably, but each has its unique function in dental procedures.
