Check out this beautiful electric toothbrush with round brush head.
I have a sweet tooth, I drink a lot of sugary coffee and I inherited some soft teeth from my British ancestors so I brush my teeth frequently throughout the day in order to avoid cavities.
Most of the day I'm at work so I'm using a crappy travel toothbrush. It would be a real luxury to be able to have a thorough brushing with an electric beauty like this at the beginning and the end of the day when I'm in the comfort of my own bathroom.
Replacement heads come in packs of 8 and it looks like they last 2 to 3 months each.
