Dentin is a hard, dense tissue that forms the bulk of a tooth, situated beneath the enamel and surrounding the pulp. It is composed of microscopic tubules and is less mineralized than enamel, making it more sensitive to temperature and pain. Dentin plays a crucial role in supporting the structure of the tooth and protecting the inner pulp from decay and injury. It also helps transmit sensory signals, which can indicate issues like cavities or fractures.
