When Special Treatment Is Required
If the nerve and the pulp of one of your teeth becomes severely infected, acute pain and sensitivity typically result. These can be signs of cavities, but often they’re an indication of a far more advanced state of tooth decay. An infected tooth or a tooth that has suffered severe trauma and has gone untreated can develop deep decay that reaches to its very roots, potentially compromising the health and viability of the entire tooth. In such cases, root canals may become necessary.
