There are two basic types of dental handpieces, those that run on air, and those that are electric. Electric handpieces are faster and more powerful than their pneumatic counterparts as electric motors have more torque. This increased speed and torque allow your doctor to remove decay at a faster rate, cutting down on the time it takes to complete a procedure. This has been shown to improve recovery time, and increase patient comfort. If you have any questions about this, or any of the equipment we use, please ask.
