What is the cheapest power toothbrush?
The cheapest power toothbrushes will be disposable ones like the Oral-B Pulsar (est. $6), but we highly recommend spending a little extra money to get a rechargeable toothbrush with a replaceable brush head since it will be the most cost effective in the long term. Our favorite model is the Arm & Hammer Spinbrush Sonic ProClean Rechargeable Toothbrush (est. $25). Similar to higher-priced power toothbrushes, it features micro-sweeping and sonic technology, two different brushing modes, and a two-minute timer that signals every 30 seconds to indicate when you should start brushing the next area of your mouth.
