Yes : Your tooth above the gumline has 3 layers: the enamel, dentin and pulp. You may have chipped off some of the enamel exposing the nerve rich area of the dentin. A simple filling can resolve your pain immediately.

Yes: You may have a chipped tooth large enough to expose the nerves in the inner layer of the tooth. If a chipped tooth exposes the nerves inside a tooth, you might notice increased tooth sensitivity and pain when chewing or when the chipped tooth is exposed to very hot or very cold food and beverages. You might need a crown or a filling to restore the shape of the tooth and prevent further damage.

Not a bad idea: Pain is the body's way of telling you something is wrong.
