Root canals are required when the nerve of a tooth is damaged and causes an Infection to occur. This damage is most often caused by tooth decay, (cavity) that has enlarged throughout the tooth and reached the pulp chamber (center of the tooth), where the nerve lives. As decay is bacterially driven, once it spreads into the pulp chamber, it causes an irreversible infection throughout the entire interior of the root system of the tooth. ymptoms to watch for are lingering pain on a tooth to cold, or hot, and possibly a "heart beat" throb that can occur spontaneously on its own without any cause. Some other causes of infections can be from by cracked teeth, leaking fillings, grinding, or trauma to the teeth.
Since the infection is irreversible, a root canal is required. A root canal is a process in which the tooth is Provided anesthetic (freezing), and any decay present is removed. Depending on the severity of the infection, Dr. Kent may need to prescribe antibiotics to control the infection prior to the root canal procedure.Once that is done, a series of instruments are used to continue to clean inside the tooth, and down the interior of all of the roots. Irrigation is also used to sterilize the interior of the tooth. Once this process is completed, a root canal filling can then be created. This filling material is then placed down the root system to seal them , and then a filling is placed on the rest of the tooth to restore its ability and function in your mouth. It is important to fill in the root canal system, as if left empty, bacteria has the ability to re-establish itself, and cause the same symptoms, and infection to occur again.
The nerve and blood vessels of the tooth are most important while the teeth are forming as they feed and guide the teeth as they develop. Once our adult teeth are fully formed, the nerve's purpose is rather diminished as the teeth no longer require any nourishment. The nerves continue to act like a sensor to detect cold, hot and pressure, yet it is safe to remove this nerve from an adult tooth if required, as adjacent structures like teeth, bone and gums will provide sensation and protect the tooth from damage.
The standard of care after a root canal filling has been placed, is to have the tooth protected from fracture or breakage by placing a crown on it. Should a break occur on a heavily restored tooth, or a tooth with a root canal, it can break at or below the gum line. These breaks can sometimes not be restored and the tooth will need to be extracted. It is in everyone's best interest to retain their natural teeth as long as possible.
