What is tooth sensitivity and its causes.

2. Acidic food irritation: Drinking acidic drinks (such as carbonated soda, lemon juice, etc.) can also easily cause symptoms of dentin sensitivity;

3. Exposure of dentin defects: Mainly caused by caries, abrasion, acid erosion, periodontal scaling, trauma and other reasons. At this time, restorative dentin is not formed in a short period of time, so teeth will appear. Symptoms of sensitivity to mechanical, chemical and temperature stimulation, including soreness and softness of teeth. Generally, tooth sensitivity can resolve on its own as restorative dentin forms.
