Dental burs are essential tools in any dentist’s arsenal, each designed for specific tasks in dental procedures. Understanding the variety of shapes and their respective uses is crucial for effective dental practice.

What is a Dental Bur?

A dental bur is a small, rotating tool that fits into the handpiece of a dental drill. It typically consists of a metal shaft with a cutting head made of high-speed steel, tungsten carbide, or diamonds. The bur’s cutting action allows dentists to remove decayed tissue, shape teeth, prepare cavities, and carry out other essential procedures. Burs are categorized by their shape, size, and material, with each variation serving a specific purpose in dental treatments.
