Fruit obtains lots of natural sugars, hence why it's not great to eat lots of it.
Make sure you don't brush teeth straight after particular foods or drink ( particularly acidic foods) because it will erode the enamel. Offering cheese after such foods or after chocolate etc is a great way to help neutralise the acid.
