The ultrasonic cavitron is a helpful tool used by the dental hygienist during your cleaning. Similar to regular scaling instruments, the ultrasonic removes the plaque and tarter from your teeth, while using a gentle water spray and vibration. Ultrasonic vibrations disrupt the bacteria and break off tarter. The water flow flushes plaque from around your teeth, while stimulating blood flow to the gums. The cavitron has a small tip, making your cleaning more comfortable and efficient.
