The enamel on tooth surface loses its protective function due to natural wear. This causes the dentin, the underlying layer of the tooth to be exposed. External stimuli such as cold, hot, sweet, acidic food or hard objects causes sensitivity to the tiny channels leading to the teeth’s nerve center and causes tooth pain.
Here are some common external causes of tooth sensitivity:
If drinking a hot beverage causes discomfort to your teeth, this is due to the rapid change in temperature, causing tiny cracks on teeth surface. If the cracks become deeper, it will harm the dentin. If the enamel on your teeth becomes thinner or is worn down, discomfort occurs when you consume hot drinks.
