The long-term benefits of ultrasonic tooth cleaning for oral health . You brush twice a day. You floss when you remember. You rinse with mouthwash for good measure.

There's a high-pitched whine and a thin mist of water, and honestly the first impression is more intense than what it actually does to your mouth.
