The purpose filled with blood vessels and nerve fibres lices below the enamel
Answers
Answer:The tooth is an amazing sensory organ. The outside of the tooth, the enamel, is the hardest tissue in the human body. The enamel surrounds another layer of the tooth called the dentin. The tooth pulp lies in the middle of the tooth. The pulp contains blood vessels, nerve fibers and other connective tissue. Although the pulp has several functions, including the formation of dentin, the sensory function of teeth is quite interesting.
The nerve fibers inside teeth are exquisitely sensitive to stimulation when they can be activated. If you have ever had a cracked tooth or had a cavity in a tooth, you know that the message sent to the brain by the teeth is PAIN!!!. (The existence of a nonpainful sensory function of teeth is being debated in the current scientific literature). However, in undamaged teeth, the sensory fibers in teeth appear to be "quiet".
