Arm & Hammer Spinbrush Pro
One of the unique features of the Arm & Hammer Spinbrush Pro battery-powered toothbrush is the combination of rotary and side-to-side actions. This combination has been patented by Spinbrush and the rotary head oscillates, which means that it spins in one direction and then the other direction for the primary purpose of cleaning the teeth thoroughly, including between teeth. In addition to the rotary head, there are secondary bristles that move from side to side for the purpose of massaging the gums and getting rid of plaque. Because this battery-powered toothbrush provides around 3,700 strokes every minute, it is designed to address the common problem of people not brushing long enough.
An important advantage of the Arm & Hammer Spinbrush Pro battery-powered toothbrush is that it is quite affordable. However, a common concern regarding this product is that the two AA batteries do not last very long. There is also a possibility for water to get inside the battery compartment.
