## Description

Product Description Remove plaque and experience a deep, effective clean with Sonicare technology, removing up to 7x more plaque vs. a manual toothbrush. Sonicare technology gently pulses water between your teeth, for a month's worth of manual brushing in just 2 minutes. The QuadPacer lets you know when you've spent the optimal amount of time on each section of your mouth while the SmarTimer signals when your 2 minutes is up. The pressure sensor flashes red to remind you to ease off, helping to prevent gum recession, while the 2 intensity settings ensure a comfortable clean that’s right for you. Going electric might feel like a big step, but with this brush you’re in safe hands. Its slim ergonomic design and familiar-shaped head gives you everything you need for an effective clean. The kit includes 1 Philips Sonicare 4100 electric toothbrush, 1 Optimal Plaque Control (C2) brush head and 1 charger. Directions Included P.when('A').execute(function(A) { A.on('a:expander:toggle_description:toggle:collapse', function(data) { window.scroll(0, data.expander.$expander[0].offsetTop-100); }); }); Safety Warning Do not use in shower.

Review: A superb toothbrush. - This is an excellent toothbrush, and a quantum leap over my old Philips one. The design is sleek and modern , yet light and easy to hold. The sonic action is the best I've experienced with an electric toothbrush. It's not especially quiet, but works well. It makes a soft 'bleep' sound if you're pressing too hard, which is a useful touch. The fact it's rechargeable with a USB is very handy as well for when travelling - no clumsy Euro plug adapter required here. It costs a bit more than other Philips models, but I feel it's worth it, especially with a longer battery life and additional features.
Review: So glad I invested in a sonicare toothbrush. - This has been game-changing for my dental routine. Instead of brushing hard and pressing too much into my teeth, I allow the brushes to glide over and the vibrations do the rest. I get such a glistening clean effect that I never got from my old electric toothbrush. The battery is fantastic, it can last me upto 4 days with cleaning twice a day. The extra setting is really good and flosses alongside my WaterPik, leaving a really deep clean. It's very good at what it does. I love the fact it's pink, too. Perfect for His and Her's sides of the bathroom, with my fiance's sonicare on the other side of the sink. Great product! Easy to use and incredibly effective. Thank you!

## Questions & Answers

**Q: Why doesn't the new 4100 model have a regular plug ?  why on gods green earth did they cheap out and put a usb plug in there ??**
A: According to the review in WireCutter (Sept 2022), you can contact SonicCare and receive a free plug adapter.  I've just ordered the 4100 on Amazon.  I don't have the serial number yet, because the product doesn't arrive until tomorrow, but SonicCare customer service just told me that they would send the free plug adapter once I provide the model number and serial number to them.  They confirmed there is no charnge.  It will take 7-10 days to receive the plug adapter once I am able to provide them with the serial number.  I'll do all of that after the product arrives tomorrow.

**Q: Does anybody make a single speed electric toothbrush? I'm so tired of cycling through the speeds**
A: Cycling is the most effective way to brush each quadrant sufficiently.

**Q: What is the purpose of having two intensity modes? How do you know when you should use one or the other?**
A: if you have more sensitive teeth and gums you can use the softer mode

**Q: What do the green and yellow lights mean? what about the beeping noise after the 2 minute brush? I thought low battery but is it replacement head?**
A: Hi! When the brush head replacement reminder light of Philips Sonicare Toothbrush HX3681/24 lights up amber, kindly replace your brush head.

### ⭐⭐⭐⭐⭐ A step up from a standard electric toothbrush
*by D***Y on 9 December 2025*

Great toothbrush. Used it for about four days now and not had to recharge it yet. Being sonic really feels like a step up from a standard electric brush. The narrow cleaning head easily reaches the back teeth and feels like they have a good clean. So far the sonic toothbrush has been excellent.
