I am pulling my hair out!
he brushes his teeth twice a day, I generally do the evening brushing with him.
as he is an asthmatic he takes inhaled steroids which can not be stopped.
unfortunately he was born with my genetics re teeth 
I really need to get this situation under control and have decided the only way is to drastically reduce his exposure to sugar.
What is the best natural sugar substitute?
and does anyone out there have any ideas how I may improve the health of his teeth apart from proper brushing of course!
