More and more dentists are recommending the use of electric toothbrushes because of their ability to reach and clean spots that traditional hand brushing doesn't do. You can get this Oral-B rechargeable electric toothbrush for 32% off regular price with free shipping for Prime members or on orders over $35. This brush features micropulse bristles and a 2 minute timer. The same toothbrush sells for $23.99 at Target.
