Final answer:
Delta fibers are nerve fibers that transmit pain and temperature information. They travel through the pulp of teeth and can cause pain when a tooth is damaged or infected.
Step-by-step explanation:
Delta fibers are nerve fibers found in the body that transmit pain and temperature information to the brain. These fibers travel through different parts of the body, including the pulp of teeth. In the dental context, the pulp refers to the soft, inner part of the tooth that contains nerves and blood vessels. When a tooth is damaged or infected, it can cause pain as the delta fibers transmit the sensations to the brain.
