The teeth have internal channels (nerves), the nerves are in charge of carrying signals that can be translated into well-being or pain, these nerves are the ones that make you feel cold, hot, sensitive or a lot of pain.

When a tooth is severely damaged due to decay or other factors, sometimes the only option is to perform endodontics, a procedure where these nerve endings are extracted from the tooth, a restoration of the tooth that remains in the mouth is performed but without any symptoms.
