About this item

Product details

Achieve 700% better plaque removal than with a manual toothbrush thanks to the Philips Sonicare 4300 Series sonic toothbrush paired with the C2 Optimal Plaque electric toothbrush head. Enjoy a powerful yet gentle clean, even in those hard-to-reach areas. The Advanced Sonic Technology provides gentle yet effective cleaning, pulsing fluid between teeth and along the gumline. With the built-in pressure sensor, you know when to adjust the pressure. Ease off and your gums will stay protected! To help you get used to the Sonicare experience, the EasyStart feature adjusts the power level of the toothbrush over the first 14 uses. Improve your brushing technique with QuadPacer and reach your recommended brushing time of 2 minutes with SmarTimer. Experience up to 14 days of regular brushing after a single charge, bringing a new level of convenience to your brushing routine (based on two periods of two-minute brushings per day on standard mode). Thanks to the included travel case, it works perfectly as a travel electric toothbrush. Did you know that brush heads become less effective after three months? The replacement reminder tracks how often and how hard you brush, then reminds you to replace your brush head once it's time for a new one. ¹ vs. a manual toothbrush ² based on a study of over 2,600 dental professionals (dentists and hygienists) conducted in the United States, Canada, Japan, China, Korea, Thailand, Germany, the United Kingdom, Switzerland, France, Belgium, Austria, Italy, Spain, Sweden in 2022-2023.

Simple at a great price

[This review was collected as part of a promotion.] The head is straight, and not at an angle to the body. My previous purchases all had the shaft on the body tat connects to the head come lose because of this issue.
