Hello, sorry if this is a silly question but are electric toothbrushes really ok for children? I used to work with someone whose gums receded in his twenties due to electric toothbrushing (his dentist said they should only be used by people without the strength to brush manually) and I read something in Junior recently that brushing your child's teeth too frequently can also be a problem. Dds are 4.5 & nearly 6. DH very keen to get a family set but I wanted some more opinions first!
