Dental erosion is an irreversible loss of dental hard tissue like enamel or dentin caused by acidic foods and drinks dissolving away the surface of the tooth .Acids associated with erosion are usually dietary for example low pH citrus fruits, fizzy drinks, pickle, sports drinks and other sources include gastric acid from the stomach due to vomiting or gastroesophageal reflux disease GERD).
Dental erosion occurs at the tooth surface where the acid causes demineralization, that is minerals are lost.
Mainly subsurface minerals are lost in dental erosion. The enamel first becomes thinner and may eventually be completely lost if dental erosion continues after the enamel is lost.
Dental erosion then removes minerals from dentin. This happens more quickly than with enamel because the dentine is softer.Erosion also results from the loss of enamel, dentin and/or cementum due to the acids.
Causes of Tooth Erosion
- The foods and drinks having acidic pH causes the loss of minerals from the tooth surface.
- Citrus fruits and beverages.
- Carbonated drinks.
- Gastric problem like gastrooesophageal reflux disease.
Signs and Symptoms of Tooth Erosion
- The eroded tooth is seen as yellowish discoloration on the tooth surface.
- Loss of enamel and dentin is evident.
- Sensitivity to hot and cold.
- Tooth becomes brittle.
- Compromised aesthetics.
- Transparent cutting edges.
- Concavity occurs in the tooth surface.
- Tooth may form divots on the occlusal surfaces.
Prevention and Treatment of Tooth Erosion
- Avoid food which are acidic in nature like citrus fruits.
- Avoid beverages like beer ,carbonated drinks.
- Treatment of acidityand other gastric problems.
- Restorations of the lost tooth structures.
- Root canal treatment should be done if there is pain and sensitivity.
