Editorial Review

The Oral-B SmartSeries 4000 Rechargeable Electric Toothbrush is a less expensive update of the popular Oral B 3000. It is the predecessor to the only slightly more expensive Oral-B 5000, which shouldn't be confused with the Oral-B Smartseries Pro 5000. With this progression to work from, we can posit an infinite number of Oral-Bs, which undoubtedly strikes fear into the heart of plaque and gingivitis everywhere. It features FlossAction technology, an in-handle display with interactive feedback, a pressure sensor, a charge level display, a portable Smart Plug charger, 1 travel case, and 4 cleaning modes: Daily Clean, Deep Clean, Sensitive and Whitening. This brush is not listed on the company's website nor is it in stock on Amazon, so it may no longer be available. However, its close sibling, the 5000 Series still is.

The size and scrubbing motion of the 'cupping/floss-action' toothbrush is great, it maneuvers well to cover all surfaces of each tooth.

Works very well, charging stand is like a circle...Comes with two brush heads, one for cleaning, one for polishing, has nice battery indicator on it.

My teeth are whiter after 2 weeks of using! I get this model because it has the same brush stroke per minute as the latest model but cheaper.

My teeth really do feel like I just stepped out of the dentist office...Each 30 second period helps by warning you to go to another quadrant of your mouth.

My teeth feel clean everyday, all the time. I never have "fuzzy" teeth anymore...I finally found a product that makes enough of a difference.
