Your dentist can perform a number of tests to see if your tooth enamel has been damaged by the effects of acid erosion. He or she will be looking for some of the more prominent signs of acid erosion in your teeth:
Transparency
Teeth may appear slightly "glassy" or transparent near their biting edges. This tends to be an earlier warning sign of acid erosion.
Discoloration
Teeth can have a yellow appearance as enamel becomes thinner and dentin shows through. Discoloration tends to occur in the later stages of acid erosion.
Rounded Teeth
As acid erosion advances, teeth can develop a rounded, "sandblasted" look on their surface and edges.
Cracks
In the later stages of acid erosion, small cracks and roughness may be visible at the edges of the teeth.
Cupping
Small dents may appear on the chewing surfaces of the teeth in advanced stages of acid erosion. Fillings also may appear to rise up.
Sensitivity
As dentin becomes exposed through loss of enamel, twinges,tingles or aches may occur.
