About Tungsten carbide burs clinic FG shank

Tungsten carbide burs are used most commonly for excavating and preparing cavities, finishing cavity walls, finishing restoration surfaces, drilling old fillings, finishing crown preparations, contouring bone, removing impacted teeth, and separating crowns and bridges. Carbide burs are defined by their shank and by their head. The type of handpiece being used determines which type of shank is needed. The procedure to be performed determines the type of head shape that is chosen.

Tungsten carbide burs also be used to trim and finish macro-filled composites and hybrid composites.

Tungsten carbide burs slice or chip away at material, leaving the tooth surface smooth and more aesthetically pleasing.
