Better oral health

[This review was collected as part of a promotion.] My teeth are a lot cleaner and my gums are healthier. My dentist can see significant improvements in my oral health since switching to Sonic toothbrush. It is the best electric brush I have ever had. I know I am brushing the right amount of time because of the two minute timer. It vibrates when I apply too much pressure when brushing and lets me know when it is time to change brush heads.

The verdict is still out on my new toothbrush…

[This review was collected as part of a promotion.] I’m still debating how much I like this new toothbrush. It’s thinner to hold than my previous Phillips. The actual brush is smaller, but that might be because I am used to the plaque – fighting brush which I believe is a bit bigger. However, there is no doubt in my mind that this new toothbrush is not as powerful as my previous Phillips.

The tootbrush size is small and it is easy to handle. However, the power is low and feels closer to a regular toothbrush than an electric one. Gets the job done for a quick clean but for a thorough session, may need to run it twice. thier bigger version is much better for power and gets better results in 2 minutes.
