Query: Shorter dentist visit

Had an Oral B of some sort before this one. It was getting kinda nasty due to the fact that I didn't rinse the body off well after brushing. Ordered this one as a replacement. Been using the 2nd style heads (the ones with the extra scrubber part making it more like a normal toothbrush size) and apparently they've been doing thier job.Getting teeth cleaned at dentist took half the time it used too. Dental hygenist asked what I was doing different and I said nothing.Only after leaving did I remember I had picked up one of these.Save 10-15 min of dentist torture....you decide if it's worth it.
