Description of electric toothbrush
The battery can be used about 50 minutes. The power is not strong as rechargeable electric toothbrush, but it is good enough to well remove plaque. The design of 3-sided bristles and 45 degree angle to the gum line can clean all three sides of the tooth and gum line at same time. With 3000 forth and back brushing movements per minute, 3-sided electric toothbrush more effectively removes persistent plaque.
