Enamel erosion is the irreversible loss of tooth tissue due to exposure to acid.

Teeth are protected by a hard layer of enamel. When the layer is damaged, worn away or when gums recede, the dentine underneath the enamel is exposed. Dentine contains tiny pores called tubules, which lead to the nerve deep inside the tooth. As a result cold, heat and food or drink with a high sugar concentration, often stimulate the nerve causing pain.

Eating too much sugar can cause tooth decay. But even if you have healthy eating habits, exercise regularly and brush frequently, you can still be at risk of dental erosion.

High acid foods can cause enamel erosion
