Most toothaches are a result of a cavity. Sugar and starch in foods are the substances that cause damage to teeth; this is why it's advisable to limit your child's sugar intake.
- The bacteria in the mouth feed on sugar and starch and produce an acid that can eat through the teeth, leading to tooth decay.
- Different types of bacteria are involved in this process that can lead to an infection in the inside of the tooth that can spread into the jaw and face.
