DS has good days and bad days on whether he will let us brush his teeth or not. we introduced toothpaste a couple of months ago and that seems to help a bit. we just dip the brushes in the top so it only gets the teeniest amount on there and use that. DH spoke to his dentist about DS and the dentist and dental nurse said it was fine to introduce toothpaste at his age.

good luck with it all!
