[missadasmith]

my DC have had the kids oral b. Had it for a few years. battery is getting tired and it's not charging well anymore and I want to replace them.

Could I get them an adult oral b electric brush? They are 7 & 9 years old. I don't see why not but I maybe missing an important point

At that age I would. You can get soft head brushes if you felt better using about them.

Our dentist said yes but use soft heads. So I bought the kids heads (star wars ones) for ds (9), she said normal heads from 11
