How Sonic Toothbrushes Work

Sonic toothbrushes use high-frequency vibrations (up to 30,000–70,000 strokes per minute) to create a fluid action that dislodges plaque and food particles from between teeth and along the gumline. The vibrations push water and toothpaste into hard-to-reach areas, making them effective for deep cleaning. They’re gentle on gums and ideal for people with sensitive teeth or gum disease.

How Ultrasonic Toothbrushes Work

Ultrasonic toothbrushes use ultra-high-frequency sound waves (up to 1.6 MHz) to break down plaque biofilm without the need for vigorous brushing. The sound waves disrupt the bacteria in plaque, making it easier to remove with a gentle brushing motion. Ultrasonic brushes are extremely gentle and are often recommended for people with receding gums or thin enamel.

Which is Right for You?

Choose a sonic toothbrush if you want deep cleaning and effective plaque removal for daily use. Choose an ultrasonic toothbrush if you have sensitive gums, receding gums, or thin enamel, and need a gentler cleaning option. Both types are effective, but the right choice depends on your oral care needs.
