What Exactly Is a Dental Bur?
A dental bur is a small, rotating cutting tool attached to a handpiece (the dental drill). It works much like a drill bit in construction—removing parts of a tooth, cleaning decay, or shaping crowns and fillings.

• To remove decay from teeth
• To shape and polish fillings or crowns
• To cut through enamel or bone
• To prepare cavities for fillings
• To create space for dental restorations

Common Types of Dental Burs
There are different types of dental burs, and each has a specific purpose. Here's a breakdown:

By Material:

• Carbide burs – Great for cutting through tough tooth enamel
• Diamond burs – Used for smooth shaping and precision cutting
• Steel burs – Commonly used for softer materials or trimming

By Shape:

• Round burs – Used for removing decay
• Pear-shaped burs – Help in preparing cavities
• Inverted cone burs – Used to flatten and shape cavity floors

By Grit:

• Coarse – Removes large amounts quickly
• Medium – General shaping
• Fine – Polishing and smooth finishing

How to Choose the Right Bur
Dental professionals choose burs based on:

• Procedure type (e.g., cavity filling, crown prep)
• Tooth location (front or back)
• Desired finish (rough cut or smooth polish)

Each bur is designed to make procedures faster, safer, and more comfortable for the patient.

Bur Dental Instruments and Safety
Sterilization is key. Dental burs are either:

• Single-use (disposable) – Used once for hygiene
• Reusable – Must be cleaned and sterilized thoroughly between uses
