Decay and Erosion

Dental decay (or cavities) is an oral disease in which a bacterial infection causes damage to the hard structures in your teeth.

Dental decay develops when the carbohydrates from the food we eat is left on the teeth for any period of time. These sugars feed the decay which causes bacteria in the mouth, allowing them to grow, multiply, and produce acids. This acid then wears down the teeth, causing mineral loss. In the very early stages, dental decay is reversible. However, further down the track the acid can lead to the formation of deeper cavities that will require restoration.


Decay that is left untreated can reach the nerve tissue of the tooth. In these severe cases, tooth extraction or root canal treatment are the only options. This is why it is important to brush twice a day, floss and have regular check-ups and professional cleans (about every six months as recommended by the Australian Dental Association).

Dental Erosion

Dental erosion is an issue becoming more common due to changing dietary habits in today's society. Erosion is the loss of tooth structure due to acid exposure, making your teeth soft. Some of the sources of these eroding acids are:

  • Sugary drinks (including soft drinks, many fruit juices and energy drinks
  • Digestive acids travelling up the oesophagus, typically during bouts of vomiting or from acid reflux

These acids can eventually erode enamel from the teeth, leading to problems such as the loss of the tooth’s natural shape, or premature exposure of the dentine (the internal part of the tooth). Erosion will also result in increased tooth sensitivity, making your teeth more vulnerable to problems like cavities. Your dentist will look out for erosion and wearing down of the teeth as part of your regular dental examination.
