Why does teeth become sensitive?

 Have you ever experienced a sharp pain in your teeth? 

At present day, Tooth sensitivity is a common dental problem faced by huge millions of people.

What is Sensitive Teeth?

Sensitive Teeth is a discomfort or a sharp pain in teeth.

Generally, people with Sensitive teeth will feel the sensitivity and experience the pain while drinking or eating something cold or hot (eg. tea, ice cream). For some people, breathing cold air, having sweet foods and acidic drinks(citrus fruits, sodas) can also trigger the pain causing sensitive teeth.

To better understand the concept of sensitive teeth, it is important to know about our teeth structure.


The outer white part of the tooth is called enamel. It is the hardest substance which protects the teeth from tooth sensitivity and damage.

Then, the underlying layer is called dentin. Enamel overlays the dentin and protects our teeth from damage. If the protective outer enamel wears away or decays, this underlying dentin will be directly exposed to the hot and the cold food we eat and makes one's tooth sensitive. This happens because the nerves inside the tooth are sensitive to temperature. On the whole, if the protective white enamel wears away, the yellow dentin and the whole tooth will become exposed to the risk of sensitivity.

What causes Sensitive Teeth?

According to dental experts, numerous factors contributes to sensitive teeth. Brushing teeth too hard, using hard-bristled brushes, tooth decay, gum disease, teeth whitening products, grinding teeth, receding gums, tooth bleaching, filling, cracked tooth and plaque buildup can wears down the enamel and cause tooth sensitivity.
