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 the procedure. There are different types of dental handpieces, including high-speed and low-speed models. High-speed handpieces are used for cutting and shaping teeth, while low-speed handpieces are often used for polishing and finishing. Both types are essential for maintaining oral health and ensuring effective dental treatments.
