Tooth Structure
At the center of all teeth is a hollow area that houses soft tissues, such as the nerve, blood vessels, and connective tissue. This hollow area contains a relatively wide space in the coronal portion of the tooth called the pulp chamber. These canals run through the center of the roots, similar to how pencil lead runs through a pencil. The pulp receives nutrition through the blood vessels, and sensory nerves carry signals back to the brain.

Famous quotes containing the words tooth and/or structure:
“Before me you are a slug in the sun. You are privy to a great becoming and you recognize nothing. You are an ant in the afterbirth. It is in your nature to do one thing correctly: tremble.”
—Michael Mann, U.S. screenwriter. Frances Dollarhyde, aka “The Tooth Fairy” (Tom Noonan)
“... the structure of our public morality crashed to earth. Above its grave a tombstone read, “Be tolerant—even of evil.” Logically the next step would be to say to our commonwealth’s criminals, “I disagree that it’s all right to rob and murder, but naturally I respect your opinion.” Tolerance is only complacence when it makes no distinction between right and wrong.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 2, ch. 2 (1962)
