“What is that vibrating tool you use to clean my teeth?”
This is one of the most effective tools introduced during the 1950’s.They were initially designed to be cutting tools for cavity preparation but high speed hand pieces won out and became the standard tool. (now we have dental lasers for many soft and hard tissue procedures)
Ultrasonic scalers vibrate at a frequency that breaks down bacterial cell walls and removes soft plaque, hard calculus and stain without the need for a blade. Hand instruments are used to complete the fine scaling that removes anything the ultrasonic scaler leaves behind.
Although the final result of ultrasonic scalers can be produced by using hand scalers, ultrasonic scalers are often quicker and less irritating to the tissue and enamel.
Another benefit of ultrasonic scalers is that your hygienist reduces the risk of repetitive motion injuries like carpal tunnel.
