Dentin is crucial for tooth health and function, providing essential support and protection. It plays a vital role in several key areas:
Structural Support & Pressure Absorption
Dentin forms the bulk of a tooth's structure, located beneath the enamel. Its softer texture compared to enamel allows it to absorb the pressure generated during chewing and biting, protecting the enamel and the inner pulp. [Source: Smilepoint Dental Care, Listerine, multiple other sources] This cushioning effect prevents cracking and damage to the harder enamel layer. A thick dentin layer contributes significantly to the overall strength and durability of the tooth. [Source: NCBI PMC]
Impulse Transmission
Dentin acts as a conduit, transmitting sensations from the outer enamel and root to the dental pulp (the soft tissue containing nerves and blood vessels within the tooth).

Enamel Support
Dentin's primary function is to support the structure of the enamel. [Source: Smilepoint Dental Care, News-Medical, multiple other sources] Because enamel is the hardest substance in the body but also brittle, dentin provides the underlying support crucial for enamel's integrity and function. The mineral composition of dentin is vital for this supporting role. [Source: Titan Dental Care]
Overall Tooth Health
Dentin’s role extends beyond its structural functions. Its composition includes minerals and water, and the complex interaction of proteins within the dentin matrix plays a significant part in early tooth development and mineralization.
