Keeping your teeth clean and fresh can be a frustrating (and boring) routine. However, Oral-B wants to make the experience of brushing your teeth fun and interactive with the Oral-B Pro 5000 SmartSeries Electric Toothbrush, which is on sale for $89.94. The Oral-B Pro 5000 SmartSeries usually retails for $159.94 and it's worth every penny, with its FlossAction brush head and MicroPulse bristles that were inspired by tools dentists use to clean teeth. The Oral-B system was designed to reach deep between teeth to remove more plaque and other icky stuff between your chompers for a cleaner and easier brushing experience. It also features five cleaning modes and a timer to let you know when to stop brushing.
