The Out-of-Sight, Essential Tooth Root
A tooth root comprises the lower two-thirds of your tooth and serves to anchor it in position and keep your jawbone healthy. The root canal space is located below the pulp chamber in what is called the radicular portion of the tooth.
The end tip of the tooth root is called the apex. Root canals can be round, oval, long oval, flattened or irregular. In most people, incisors, canines and premolars have one root, while molars have two or three, each of which can get infected. Due to the complex branching of nerves, most teeth have an intricate internal anatomy.
