A smile is the thing that you wear. Now imagine that the teeth look yellow. Our teeth comprise the outer hard enamel. The dental pulp lies soft and is encased with dentin. The cementum that lies over the dentin attaches the tooth to the jaw.
Dentin is a soft portion between the enamel and pulp. They are mainly present in the pulp’s uppermost layer. It initially forms the pre-dentin and then becomes a substance called dentin.
Denti is classified into 2 categories The primary part is the upper part near the enamel, and the secondary part is in contact with the cementum, and that forms and gets corroded into tertiary form.

Dentin’s function
The function of dentin is to support the structure of enamel and its softer texture helps in decreasing pressure from eating that transfers the impulses from enamel to pulp. Where the nerve ends and receives the signals. It protects the pulps.

Denyin and Decay
The health of our teeth determines their color. If the teeth are yellow in color then it would lead to unhealthy teeth. If the teeth are black or grey then it can indicate a cavity. The most significant thing is that enamel degradation plays an important role in our teeth’s health. When the top layer of teeth gets degraded then the dentin’s layer is visible. This gives teeth yellowish color. This is the reason for unhealthy teeth that can lead to discoloration. The dectin can cause teeth to be brittle and edges to a rough. However, exposure to dentin would cause a condition called Dentin hypersensitivity.

What is Dentin hypersensitivity?
Denyin hypersensitivity is due to dentin exposure to thermal, chemical, or stimuli. Thereby it can cause extreme sensitivity and pain. It is a dental issue. As the enamel gets affected by the cavity and acid imbalances.

Care and Prevention
As dectin is regenerative, bacterial growth should be in control. Achieving proper oral hygiene is important. Brushing, and eating a proper diet can be a good solution. The plaque and other accumulations must be avoided in order to prevent and cure dentin.

Conclusion
This is my short blog on dentin and its important function. Dentin is a yellowish substance that causes tooth and teeth problems. To avoid these problems take care of your teeth by brushing and avoiding the acidic diet.
