Because : Because the nerve in the tooth was removed during the root canal procedure the tooth is unable to respond to changes in temperature. Though every root canal treated tooth does not need a crown, root canal treated teeth are more prone to fracture due to increased brittleness. Fractured teeth typically cause pain on biting pressure or increase the risk of infection as bacteria can migrate down the fracture. I would look at adjacent vital teeth as the source of your discomfort to changes in temperature either due to root exposure of decay. See your dentist as this is a sign that some treatment is required.

As : As mentioned by dr.Funari, any adjacent tooth will be the answer, although molars in general require a final restoration and that will be the build up and the crown, contrary to any front tooth, if no restoration is found other than the access for the root canal.
Please call your dentist for a check up with x-rays to determine the source of your sensitivity to cold temperature.
Good luck!

Since : Since there is no nerve to this tooth, adjacent teeth are the more likely contributers to this pain. Supporting bone and gums can be involved as well, but not normally with thermal concerns. See your dentist asap, but you may want to consider a crown on this tooth that had the root canal.

Its the adjacet toot: A root canal tooth can not be cold sensitive. It is probably the tooth in front or in back of the root canal treated tooth.S see your dentist.
