A: Hello! Yes, the Philips Sonicare 4100 Power Toothbrush is made in China.

Difference is that the 4100. Series has two brushing intensities compared to just the one of the protective. Clean the options are high and low on the newer.

It does this by reducing the number of bristle movements. Should you brush too hard it's really easy to know when it has been triggered you get a differing vibration pattern in the handle.

Instead of oscillating and rotating, the Sonic toothbrushes vibrate at a rate of 31,000 strokes per minute. Their patented sonic technology allows a dynamic clean action that drives fluid between teeth and along the gum line.

14 days From the manufacturer

14 day The Sonicare 4100 is an excellent value as it is slim yet powerful, and has a ton of extra features along with a 14 day battery life.

Philips' Sonicare 4100 Series Sonic Electric Toothbrush is our top recommendation because it offers all the features dentists, dental hygienists and periodontists told us to look for without unnecessary extras that drive the price up.

Yes, you still need to floss even if you use an electric toothbrush. But a sonic toothbrush does clean all the deep surfaces that are hard to reach, which makes it better for oral care than a manual toothbrush.

Sonicare is the pioneer of creating toothbrushes that use ultrasonic technology. Sonic technology gives Sonicare toothbrushes the advantage of superior biofilm removal (biofilm is the thin layer of plaque and debris that form on our teeth). If the biofilm is not adequately cleaned, this leads to decay and disease.

It is recommended to replace your Philips Sonicare Brush Head every three months of normal use (brushing twice a day) or when the blue indicator bristles wear out. One reason is because brush heads can get weary and will be less effective in removing plague.
