Keep your teeth clean with the Philips One Battery Powered Toothbrush with Case. The new electric toothbrush by Philips cleans your teeth better for a brighter, whiter smile. It has micro vibrations and contoured bristles that gently clean and polish your teeth at the touch of a button. It works for 90 days on a single AAA battery, that’s three months of whiter, brighter smiling. The One buzzes every 30 seconds encouraging you to move on to the next part of your mouth. A longer buzz at two minutes lets you know when the job is done. It features a sleek, lightweight design with a portable case that makes it easy to carry while travelling.
