Here are a few models that I found while looking on Amazon.com.   Can you think of any other models or features to include on my list?

I'm not super familiar with the world of electric toothbrushes.  But I know that there are a number of possible features that might be important.  First, how long does it last?  Is it the kind of brush you can replace often, or just once in a lifetime?  Are there multiple brush heads available?  Do the brush heads work with an alternative energy source?

I have sensitive teeth that get damaged easily. What is the best toothpaste to keep them in good condition?

I can think of two possible solutions for this problem.  The first is to use an electric toothbrush.  It would be designed to have a less aggressive scrubbing movement, and be easier on sensitive teeth.
