US Senate and Immigration. Every year, hundreds of bills are introduced in the U.S. Senate to control illegal immigration, build fences on the U.S.-Mexican border and to grant benefits in the form of temporary visas and permanent residence to various types of immigrants.
When pulp is damaged, it breaks down, and bacteria begin to multiply within the pulp chamber. The bacteria and other dying pulp remnants can cause an infection or abscessed tooth. An abscess is a pus-filled pocket that forms at the end of a toothâs root. In addition to an abscess, an infection in the root canal of a tooth can cause:
The root canals, which contain the pulp, extend to the bone. Deep tooth decay, or an injury, can cause serious damage and infection to the pulpâs nerves and vessels. A âroot canalâ (the technical term is endodontic treatment) cleans out the infected pulp chamber and repairs the damage. Many times this pain is felt after a recent dental procedure such as a filling or a crown. 2  A rule of thumb is that if the pain does not subside within a 6 week period of time or becomes increasingly severe, then a root canal will be required (make sure the bite is correct!).
