Ds (2.9) has always had lovely white teeth. Recently I've noticed they have started to go a bit yellow, particularly the canines, and I wondered why that might be. He doesn't eat many sweet things, doesn't have much juice and has his teeth brushed/brushes his teeth twice a day (although not always very thoroughly - you know what toddlers are like!).
Only thing is, he has taken against milk and although he has cereal and perhaps a glass of milk (with fruit in it) for tea, he probably doesn't have a pint or whatever is recommended.
Do you think it is lack of calcium which might be causing the yellowing of teeth? I'm assuming it is not because of lack of proper brushing since the brushing is as good or bad as it has ever been (although I suppose it might be a cumulative build-up if we are not brushing properly).
Anyway, hope this makes sense and grateful for any thoughts. We're not due to see the dentist for 7 months.
