The Cavitron ultrasonic cleaner is a state of the art instrument that has proved to be an extremely successful tool in removing tartar from both above and below the gum line. The Cavitron unit is so gentle that it can even be used to administer deep cleaning and gum therapy, many times without the need for anesthetic. Having your teeth cleaned with the Cavitron unit is a safe, effective, and painless alternative to traditional cleaning methods. A Cavitron vibrates at the speed of sound, so quickly that you can hardly feel any movement.
