What foods cause cavities?
Foods high in sugars and starches feed the plaque that can cause tooth decay. Sticky candies like lollipops, caramels and jelly beans are particularly harmful, but cookies, chips and other starches can be equally harmful because they break down into simple sugars. Carbonated and non-carbonated soft drinks and fruit juice contain lots of sugar and acids that can wear away tooth enamel.
Also, note, fruit and other foods can be healthy to eat, but also contains large amounts of natural sugar which can lead to dental cavities. Encourage your child to brush or wash their mouth out with water after consuming any of these foods.
