Root canals are small passageways that extend from beneath the top of the tooth down to the tip of the root. Each tooth contains between one and four root canals.
Many dental problems arise when infections spread to the pulp, the innermost part of the tooth that houses blood vessels, nerves, and connective tissue. When an infection reaches this area, it can extend into the roots, causing pain and complications. Traumatic injuries to the tooth can also damage the pulp, leading to similar issues.
A diseased tooth typically presents symptoms such as pain and sensitivity. However, if the infection continues to spread, it can lead to the formation of small pockets of pus (abscesses), resulting in more serious problems.
The Role of Root Canal Therapy
Root canal therapy is an effective treatment designed to save a tooth from extraction. The procedure involves removing the infected tissue, stopping the spread of infection, and restoring the remaining healthy tooth structure. Before root canal therapy was developed, extraction was the only option for treating a diseased tooth.
The Procedure
Root canal therapy usually requires one to three visits. During the procedure, a small hole is drilled into the tooth to access the inner chamber. The infected tissue is removed, and the chamber is thoroughly cleaned, disinfected, and reshaped. The cleaned area is then filled with a flexible material and medication to prevent further infection. In some cases, a temporary filling is placed until a permanent crown can be applied to seal the tooth.
Most patients experience little to no discomfort during or after the procedure, and the restored tooth can last for many years, nearly as long as a healthy natural tooth. Root canal therapy is a safe and reliable solution to preserve your smile while addressing serious tooth infections.
