Are they a good idea? Ds1 has been asking for one for two years - he'll be six at Christmas and I'm wondering whether to get him one. Anything that might add some enthusiasm to toothbrushing can only be a bonus!
Any thoughts/tips on use? I've never had an electric toothbrush, so have no idea! Any recommendations? I've been looking at them and the ones he wants all have non-changeable heads, so I assume the whole thing will have to be replaced every 3 months or so. Or is there a good one with changeable heads?
TIA from an electric-toothbrush-virgin!
