Power & versatility...the Rotadent lacked power and versatility. I mean it's a decent brush and I was happy with it for years. But when I got braces and brushed with it, it took
forever to clean my teeth really well. Since our cleaning routine already increases because of the braces I wanted to simplify as best as I could. So I gave the Sonicare a shot and it worked beautifully, it was thorough, easy to manuever in my mouth, it felt good to my teeth and gums and I didn't have to brush for 10 minutes to make sure I got everywhere.
I highly recommend everyone to try it, I've tried them all, literally...and I'm a clean freak when it comes to oral care so I'm glad i found something that
really does the job.

I blog about my experiences in braces and I have one entry ALL about cleaning tools....some find it helpful. Here's the direct link:
