Modern advice is to brush before eating. You clean the teeth so stuff doesn't stick to them. Brushing after eating brushes when your teeth are being attacked by acid.

> When should I brush my teeth?

> Brush your teeth for at least two minutes in the morning before breakfast and last thing at night before you go to bed.

> Never brush your teeth straight after a meal as it can damage your teeth, especially if you've had fruit, fizzy drinks, wine or any other food that contains acid.

> This is because tooth enamel is softened by the acid and can be worn away by brushing. Instead, wait an hour after a meal before brushing your teeth to give your saliva chance to neutralise the acid.

Obviously, I'm not a dentist and nothing I say is meant to replace anything an actual dentist tells you.

Huh, that makes sense at least; I'll have to look into that.
