Dental erosion - Preventive dentistry
Erosion is the loss of superficial tooth tissue due to the action of acids other than those formed by bacteria in the mouth. We classify the acids as follows:
- Intrinsic acids are acids that originate from the body, such as heartburn during burping or vomiting;
- Extrinsic acids can be acids in food, but also in the environment, such as fumes in factories.
By brushing the teeth immediately after vomiting or using acidic foods, the soft enamel layer is polished away and the tooth erosion is accelerated.
The glaze dissolves slowly through frequent consumption of acidic foods. The consequences are:
- Dull enamel and disappearance of shape details.
Advanced dental erosion:
- Vanish from the glaze cap. The yellow-colored dentin becomes visible. This wears out faster than enamel; this creates hollows;
- With advanced dental erosion, restorations will protrude above the tooth surface;
- Sensitivity to heat and cold (see image below).
