Root canal treatment (also called a root canal) is performed when decay will likely damage or has already infected a tooth. During a root canal, the nerve is removed from the center of a tooth. This can prevent or drain a painful infection in the tooth. This procedure can relieve toothache, stop infection, and promote healing.
Crowns that seal the top of the tooth and strengthen it may come loose over time. They may need to be repaired, redone, or cemented on again.
A root canal is needed when tooth decay is likely to cause permanent damage to the pulp or has already done so.
A root canal removes the pulp inside the tooth and replaces it with filling material. It can effectively treat or prevent an infection.
If you have an infected tooth, bacteria from the mouth can enter the bloodstream and cause infections in other parts of the body. People who have a hard time fighting off infections may need to take antibiotics before and after a root canal. Such people include those who have artificial heart valves or were born with heart defects.
Because a root canal removes the pulp inside the tooth, the tooth becomes more fragile and may break more easily if it is not covered with a crown or cap.
A root canal needs to be done as soon as possible to avoid a severe infection, which can damage the bone surrounding the root of the tooth and infect other teeth.
If you have a severely decayed or infected tooth, you may not want to go through the expense and discomfort of a root canal and crown fitting. Instead, you may choose to have the tooth removed (extracted). The space can be left open or restored with an implant or bridge..
