Ultrasonic toothbrushes generally receive favorable reviews. Reviews for several brands of ultrasonic toothbrushes are available on Amazon.com and GetHealthyTeeth.com. An ultrasonic toothbrush is a type of electronic toothbrush that vibrates at a high speed for optimal cleaning.
A number of ultrasonic toothbrushes receive four or more stars on Amazon.com as of 2015. Reviews on Get Healthy Teeth note the ultraviolet sanitizers included with some toothbrushes as a positive selling feature.
According to HuffingtonPost.com, sonic and ultrasonic toothbrushes vibrate at approximately 30,000 strokes per minute. This level of vibration helps force water and toothpaste between the teeth and into small spaces that may not be reached with manual brushing. Overall dental hygiene remains dependant on individual brushing habits.
