Some simple rules on how to identify a bad food for teeth that can cause cavities are:
Foods or drinks with a high concentration of sugar are generally foods that cause tooth decay.
Acidic drinks with a low pH value damage the tooth enamel and cause cavities.
Sticky foods, that are not washed away of teeth easily by the saliva, increase the exposure of teeth to sugar and acids, and the risk of tooth decay.
