DS 14 - regularly 'forgets' to clean teeth.. they're often yellow & gunky & we point this out & stress the likely outcomes, but beyond forcibly cleaning them for him, how can we ensure he does them? We always maintained a morning & evening routine as a child - it just doesn't seem to have stuck. Dentist has a go at him, but that wears off between visits. Is this just a teen boy thing he'll grow out of?! Do we need to actively bribe him to do this as well as pretty much every other day to day task?!!
