Before I can ask my question, I have to explain a few things. Sonicare is a type of electric toothbrush (www.sonicare.com). My model has something called QuadPacer where you brush your teeth by “quadrants.” It’s basically a timer that beeps every 30seconds up to 2minutes at the end of which the toothbrush automatically turns off. You brush the first quadrant for 30seconds, then switch over the second quadrant when the toothbrush beeps, and then continue to the third quadrant when it beeps yet again. This is to ensure that you brush at least 2minutes, which is the recommended amount of time suggested by dentists supposedly.
The strange thing I found with the instructions is how the quadrants of your teeth are divided. The four quadrants are the top front of your teeth, the top back, the bottom front, and the bottom back. So my question is why aren’t the chewing surfaces included in the recommended 2minutes of brushing time? When you use a regular brush it’s completely standard to brush over the chewing surfaces of your teeth.
Yes I know that its possible to turn the toothbrush on again and brush the chewing surfaces (In fact the instructions mentions this as well, but its implied that its only optional). But I believe that all the claims that the toothbrush makes on removing plaque and reversing gingivitis is based on only the 2minute brushing cycle which DOESNT include cleaning the chewing surfaces. Can someone give me the straight dope on why it seems that brushing chewing surfaces just arent as important as the front and back surfaces and inbetween?
