Tooth decay is one of the most common diseases suffered anywhere in the world. It is defined as the formation of cavities (holes) in the teeth as a result of the action of bacteria. Acid from bacterial action on the teeth eats away and destroys the protective enamel and allows a cavity to form. If this is left untreated, decay spreads to the dental pulp in the middle of the tooth allowing bacteria to attack the exposed area, which causes pain and can eventually cause infection and ultimately the death of the pulp and tooth.
You may not always be aware of cavities developing in your mouth, which is why it is important to pay a regular visit to your dentist. If you experience tooth pain, this may mean that the cavities have already started causing damage. Good oral hygiene is essential to prevent cavities.
