## Description

Product Description Remove plaque and experience a deep, effective clean with Sonicare technology, removing up to 5x more plaque compared to a manual toothbrush. Sonicare technology gently presses water between teeth, for a month of manual brushing in just 2 minutes. The QuadPacer lets you know when the optimal amount of time has spent in each section of your mouth while the SmarTimer indicates when your 2 minutes are finished. The pressure sensor flashes red to remind you to be relieved, helping to prevent gum recession, while the 2 intensity settings ensure a comfortable cleaning that's right for you. Getting electric may seem like a big step, but with this brush you are in safe hands. Its slim ergonomic design and familiar shaped head give you everything you need for effective cleaning. Kit includes 1 Philips Sonicare 4100 electric toothbrush, 1 optimal plate control brush head (C2) and 1 USB charger (wall adapter not included). Directions 1) Moisten the brush head, apply the toothpaste and select the desired intensity; 2) Distribute the toothpaste evenly over the teeth and gums; 3) Start brushing, making sure to cover all areas of the mouth also using the QuadPacer; 4) Brush your teeth for the recommended 2 minutes, indicated by the SmarTimer; 5) Be gentle, letting the brush do the work, and use pressure sensor as a guide; 6) Replace the brush head every 3 months.

Review: Effective toothbrush, good for sensitive or bleeding gums. - I've been using a oral B oscillating toothbrush for years, but have recently been getting bleeding gums - thought I'd try a sonic brush. Am very pleased with it, I'm not an expert, but it does clean teeth effectively and my teeth do feel cleaner than with the oscillating brush. Most importantly for me - no more bleeding gums! (pressure sensor on the brush warns me if I'm pressing to hard). I also like the timer which lets me know how long to spend brushing each section of teeth.

## 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.
