Dentists employ an array of tiny, handheld cutting instruments called dental burs for a variety of functions, ranging from trimming away tooth decay and preparing for dental fillings to refinishing tooth enamel. These burs come in all sizes and shapes and prove crucial to dental operations.

A fissure bur, commonly referred to as a “fg”, is designed specifically to clean out the crevices which form on the chewing surfaces of teeth. These burs are prominent when it comes to accessing narrow areas or stubbornly accumulated decay as they make ease of access to those hard-to-reach spots an attainable reality.

Fissure burs come in assorted sizes and forms. Most popular is the round-ended variety, recognized by its cylinder-like body, featuring a sharply pointed tip.

When dealing with small, isolated bits of decay, round-ended fissure burs are the simplest tool to use. However, if extensive removal of caries is necessary, or if tooth shaping needs to be accomplished, these burs are far less effective.

To carry out such chores, a specific kind of fissure bur is mainly employed. This kind of bur boasts a plain, elongated shank and terminates with a pointed, diminutive point; they are more popularly known as flat-tipped fissure burs.

When compared to those with perfectly circular endpoints, flat-ended fissure burs can be a bit on the tricky side to handle, yet they are particularly conducive to managing mountainous swaths of carious tooth tissues, and for optimizing the surface of dental slabs of enamel.

Care must be taken when operating any model of fissure bur, as these tools have the capacity to harm enamel if handled with insufficient care.

If using a fissure bur proves to be too daunting of a task, the best recourse would be to seek guidance and expertise from a qualified dental care provider.
