This Philips Sonicare toothbrush is under $40 right now — and 21,000 reviewers adore it

What is it?

While the American Dental Association says you can get an effective clean with either manual or electric toothbrushes, it’s hard to deny how good your teeth feel after a round with a powered brush. Well, heads up: The best-selling Philips Sonicare 4100 Power Toothbrush, which has more than 21,000 rave reviews, can be yours for a mere $40 if you snap it up today on Amazon.


Philips isn’t messing around with this electric toothbrush, which promises to remove up to seven times more plaque than a manual toothbrush. It offers two intensities and a pressure sensor to help you get that just-right level of clean.

Why is it a good deal?

This toothbrush hasn’t been priced this low since Prime Day in July, giving you another chance to save at a rock-bottom price. At just $40, Philips’ 4100 is significantly cheaper than much of the competition.

Why do I need this?

A Philips Sonicare toothbrush is really a no-brainer. First of all it’s suitable for anyone, and that includes you. And of all electric toothbrush brands out there, Philips Sonicare is the one most recommended by dentists. In fact, brushing with the Philips Sonicare 4100 Electric Toothbrush is truly like going to the dental hygienist for a cleaning every single day. You know that silky smooth feeling when you run your tongue across your teeth after a professional deep-clean? That, but on demand.

This Philips Sonicare model has me particularly intrigued. It doesn’t just remove more plaque than a manual toothbrush — it removes seven times more plaque. The device has a two-minute timer, which lets you know you’re brushing according to the ADA’s recommendations. Studies show that people who brush for two minutes remove 41% of plaque — compare that to folks who brush for one minute and remove 27% of plaque.

The Philips Sonicare 4100 Electric Toothbrush also has a pressure sensor that lets you know when you’re brushing too hard, a feature that reminds you it’s time to replace the brush head and a battery indicator that lets you know it’s time to recharge — but the battery lasts 14 days!

So many features, so little money. I can hardly believe Amazon is selling this little powerhouse for $40.

What reviewers say

Let’s check in with those 21,000+ customers who are absolutely in love with their Philips Sonicare 4100 electric toothbrushes.

“I got this one to replace my 7 year old Sonicare and the difference is amazing,” said one fan. “Even on the low power setting, it has a lot more oomph, the bristle is much stiffer and somehow cleans a lot better, and I love the feature where the head starts vibrating if you press too hard. My dentist had told me in the past that I brush my teeth too hard, so this is a great feature.”

A fellow happy brusher raved about the “great clean” they got. “It really does clean SO much better than the moving bristles on the battery powered one,” they said. “Mouth feels better after brushing and gingivitis has really improved. Battery life is excellent.”

This sale price won’t last: Grab your own Philips Sonicare 4100 at a sweet discount while you still can.
