What do you actually understand about your teeth beyond the fact that they help you grind up food to digest?

Of course, tearing and chewing is their main function and for this they need to be incredibly strong. The pressure exerted is between 30-50 pounds of force for the front incisors to cut and tear, and around 200 pounds of force for the molars to grind and chew.

The crown is the name given to the tooth that can be seen above the gum line. It is covered with enamel which extends to the beginning of the root. Enamel is a strong material composed of calcium and phosphorous. As the hardest substance in the body it is ideal for biting and chewing as well as protecting the tooth from damage.

Depending on how much pressure it needs to endure, a tooth can have between 1-3 roots. Cementum, a yellow bonelike substance, covers the root. It is not as strong as enamel and vulnerable to bacterial decay if exposed by a receding gum line.

Dentin and pulp are the tissues inside teeth. Dentin’s strength is in between that of enamel and cementum and it fills the greater portion of the inner tooth while pulp fills a chamber at the core. This soft tissue chamber extends from the crown into the root and is filled with connective tissue networked with nerves and tiny blood vessels that nourish the dentin and keep the tooth alive. The nerves communicate pain when the pulp is infected or damaged.
