Toothaches are caused by an inflammation of the pulp inside the tooth. The pulp is part of the inside of the tooth that has tissue and nerves. A toothache is usually the result of either a dental injury or dental caries (cavity). Dental caries are often a result of poor dental hygiene.
Toothaches and cavities
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.
