I have, after years of deliberatng, decided to use an electric toothbrush. Its been 2 years and I want to know what I should be expecting. Maybe I am sleepy when I a brushing so I don't notice but asking still. Novamin sounds interesting. Its available here on amazon so I might splurge on it but again, what I am to expect out of it as opposed to regular Colgate ?
