A dental handpiece is a tool that drills into certain parts of the tooth with high speed. When you have those painful caries in the tooth and a visit to the doctor, he suggests you to go for a filling which is basically done after drilling the tooth with a dental handpiece.

These dental hand pieces generally use their rotating motion to make a hole in your tooth. Now a days there are many advanced drills which can rotate at a speed of 800,000 rpm. They contain minute alloy bits which are also known as “burs”. These burs come with different shapes specialized for various applications. While working on your teeth the dental handpiece gives out a shrill sound which often scares the patient.

There are various types of dental handpieces available in the market. They are generally segregated in two particular categories depending upon the speed of the handpiece. The two categories are high speed dental handpiece and low speed handpiece. Generally these handpieces use a system which is operated by air.

They contain an air driven turbine inside. This generates the rotational motion of the dental handpiece. The high speed handpiece is also known as the “Contra-angel handpiece”. They are used to remove the high deposition of unnecessary particles like spoiled enamel or dentin from the tooth cavity.

Some of the advanced models can rotate at the rate of 400,000 rpm. The low speed handpiece is operated by an inbuilt motor and their speed is around 80,000 rpm. These handpieces are used to carry out prophylaxis or refining the cavities. The dental handpiece requires regular lubrication and rinsing to last long.
