A dental handpiece is a crucial tool used by dentists to perform various procedures, such as drilling, polishing, and cleaning teeth. It is a small, handheld device that operates at high speeds, allowing for precise and efficient work on dental materials. The handpiece typically connects to a dental unit, which provides air and water to assist in cooling and cleaning during procedures. There are different types of dental handpieces, including high-speed handpieces for cutting hard tissues and low-speed handpieces for finishing and polishing. These instruments are designed for comfort and control, ensuring that dentists can provide effective treatment while minimizing discomfort for patients.
