ConsumerSearch.com lists Sonic toothbrushes as one of the best brands of electric toothbrush available on the market and features many positive reviews. As of May 2015, the DiamondClean Rechargeable Sonic Electric Toothbrush has over 1600 reviews and has received an average of 4.5 stars out of 5 on Amazon.com.
The Philips Sonicare DiamondClean Rechargeable Sonic Electric Toothbrush is dubbed the "Cadillac of electric toothbrushes" by Good Housekeeping, which praises the toothbrush's multiple modes and its smooth, glossy interface. The toothbrush has a smaller head and brush size, allowing it to reach more parts of the mouth.
Sonic toothbrushes can improve a person's oral hygiene significantly, reports Thomas P. Connelly of the Huffington Post. However, these improvements are largely dependent on a consumer's personal habits; people who do not floss regularly may find that a sonic toothbrush cleans areas that a standard toothbrush cannot, but flossing is still the best way to clean certain parts of the mouth. The vibrations of a sonic toothbrush, somewhere between 30,000 to 40,000 strokes per minute, propels water, saliva and toothpaste further into areas between the teeth and below the gum line. A sonic toothbrush may also encourage people to brush longer, helping improve their oral hygiene overall.
