The white outside portion of a tooth is called the enamel. Inside the enamel is another hard layer, the dentin. There's a small chamber at the center of the dentin called the pulp chamber. Inside the pulp chamber is the tooth pulp, a soft tissue made up of nerves, arteries, and veins. The pulp extends from the pulp chamber all the way to the tip of the root through a narrow channel called the root canal.  Contact Dr. Miely today  so we can assess your particular situation.
