O que tem dentro do canal da raiz de um dente?
Um nervo, uma arteria, uma veia e outros tecidos
Running through the center of the tooth is the root canal. Everyone knows it contains a nerve. Many are not aware that it also contains an artery, vein, and other tissue. As the blood flows through the artery every day and night, it drops nutrients into the fluid in each of those dentin tubules — the same way blood vessels drop nutrients into each cell of the body. The nutrients present in those tubules travel to all parts of the tooth. That is the real hidden secret about what keeps teeth alive and healthy.
