Does it matter what I eat?: Dr Pratish Dholakia, Dentist
It does matter what you eat. From a dentist's point of view, it is how often you are having sugary snacks between your meals. Not just the usual culprits like biscuits, cakes, chocolate, a lot of savoury foods will have sugar added into the flavouring, which is bad for your teeth there.
And a lot of patients think that, you know, if they have one Malteaser, or one sweet in between meals that's fine - once again it's not how much sugar you have, it is how often you're having the sugar. Every time you have a snack or meal, your teeth will be weakened, and rotting, and dissolving away, for up to half an hour afterwards.
