Causes of tooth sensitivity.

The causes of tooth sensitivity are like an iceberg. Although you only see the sharp pain on the surface, there are many unknown factors hidden behind it. Imagine that your teeth are like a fortified castle, with enamel and dentin as its defences. However, with the wear and tear of everyday life, this castle's defences can be weakened. Excessive brushing effort, for example, is like a destroyer's axe, constantly hacking away at the teeth's defences, leaving the dentin gradually exposed. Then there's life's eating habits, where excessive acidic foods and drinks are like a relentless acid rain, constantly eroding the defences of the teeth, making the enamel thin or even disappear. And when the defences of this castle are weakened, the nerves of the pulp are perceived by external stimuli, producing that unbearable sensitive pain. In addition, problems such as periodontal disease, tooth wear, or cracked teeth can expose the dentin and lead to tooth sensitivity. This is the main cause of tooth sensitivity, a painful reaction triggered by the breakdown of defences.
