We have an electric toothbrush and GS has "gone off" it. He prefers to use the ordinary one these days - at ours anyway. He probably has no choice at home. I don't know whether DD supervises his teeth cleaning now - she probably thinks he's old enough at nine to do them properly, but I still do, especially the bedtime one. Fuss pot, me! From the start he had a problem with mint flavoured toothpastes. Even the ones that were fruit flavoured tasted minty, but DD managed to find one on line that was completely flavourless and he has been using that for years. The dentist says it's perfectly okay. I offered him soot and salt like his great grandad used to use, but he politely declined!
