On the contrary, a regular toothbrush is more work, not less. I was amused to find this out after using a Sonicare toothbrush for a number of years. After it finally wore out, rather than buying another expensive toothbrush I just picked up a pack of the old fashioned kind. When you haven't been brushing your teeth that way for years, you notice the particular muscles aren't used to that exact motion :). Sad, yes, but true.
