Question 1

Is the 21-day battery life realistic, and how does it hold up over time?**

Accepted Answer

The 21-day runtime is based on two uses per day with a standard cleaning mode. Many users confirm achieving close to this when new. It's important to note that, like all lithium-ion batteries, capacity can gradually decrease with time and charging cycles. Some long-term users report a reduction after several months, so you may eventually need to charge it more frequently.

Question 2

Are my old Philips Sonicare brush heads compatible with the 6700?**

Accepted Answer

Yes, in most cases! The 6700 Series uses the standard Sonicare brush head connection, so it's compatible with all Philips Sonicare brush head families (like Optimal, ProtectiveClean, DiamondClean, etc.). This is a common point of relief for upgraders. However, for the best experience with the pressure sensor, Philips recommends using their newer brush heads designed for it.

Question 3

What's the deal with the travel case? I've seen mixed reviews.**

Accepted Answer

The included travel case is a hard-shell design that protects the brush head and handle. While it does its primary job, some users on social media have noted it feels less premium than the brush itself and can occasionally pop open if overstuffed. It has a slot for one brush head but does *not* securely hold the charging plug—you'll need to pack that separately.

Question 4

Who would benefit most from the 9 settings versus a simpler, cheaper model?**

Accepted Answer

If you have specific oral care needs like sensitive teeth, gum care focus, or desire a whitening boost, the 9 settings are a great fit. It's perfect for someone who wants a customizable routine. If you just want a reliable, basic clean without the extras, a model like the 4100 Series might offer better value. The 6700 is often praised by users upgrading from a basic brush who love the new level of control.

Question 5

What if the pressure sensor feels too sensitive or annoying?**

Accepted Answer

The pressure sensor is designed to be preventative, alerting you at the first sign of excessive force to protect gums. Some users do find it very sensitive initially. The good news is you can adapt your technique—using a much lighter touch than you might be used to. Most users get accustomed to it and find it becomes a helpful, unobtrusive guide for healthier brushing habits within a few days.
