After spending hours diligently researching the entire US electric toothbrush market, I chose this sonic Philips 6100 model. I would have also tried an ultrasonic toothbrush but found that most were “currently unavailable” and/or offered by small companies with service issues. Sonic and ultrasonic are different but are often confused in review articles, even in some written by “experts”. All of the current model Philips sonic toothbrushes operate with 31,000 brush strokes per minute, so they will all remove plaque and do an excellent job of cleaning. The sonic technology creates perceptible micro bubbles that circulate between teeth and below the gumline which assist in making my mouth feel extra clean. Various features are important to different users and influence pricing structure.
Having been a hard brusher for much of my early life, the pressure sensor was theoretically one of the most important reasons that I chose this toothbrush. In my opinion, one has to press unreasonably hard while brushing to elicit the pressure sensor’s vibration change. So in its current version, I do not think this feature is realistically very helpful.
The whitening feature is real, but people should realize that it is not intended to be a whitening treatment to change the actual shade of the teeth. It can help minimize / remove extrinsic stains from coffee, wine, etc if used appropriately.
For me, an important positive not usually mentioned is that this toothbrush will lie stably on its side on a flat surface vs rolling around. So if you want to lay it on a countertop and apply toothpaste, it will stay in position and not roll over, spilling toothpaste.
The finish is rather slick, and it can be hard to keep a grip at times. The addition of a rubberized grip strip could be an improvement. I wrapped a rubber band around the handle which is tempering the problem.
Overall, this is an excellent toothbrush with quad pacer timer, 3 intensity levels, Smart Brush technology and a brush change reminder.
