Root Canal Treatment

Root Canal Treatment

Root canal treatment is used to save a tooth when the dental pulp becomes inflamed, infected, or irreversibly damaged. The pulp is the soft tissue inside the tooth that contains nerves, blood vessels, and connective tissue.

Pulp damage may be caused by deep tooth decay, cracks, fractures, repeated dental procedures, leaking restorations, traumatic injury, or severe tooth wear. Infection can spread through the root canals and into the surrounding jawbone, potentially causing an abscess.

Common symptoms include persistent toothache, sensitivity to hot or cold, pain when biting, gum swelling, a pimple-like lesion on the gum, tooth discoloration, or facial swelling. In some cases, the nerve may die and the tooth may become symptom-free despite ongoing infection.

Diagnosis usually involves a clinical examination, sensitivity testing, percussion tests, bite evaluation, and dental X-rays. Cone beam computed tomography may be used in complex cases to identify additional canals, fractures, unusual anatomy, or infection around the root.

During treatment, the dentist or endodontist creates an opening in the tooth and removes the damaged pulp. The root canals are cleaned, shaped, disinfected, and filled with a sealing material. A temporary filling may be placed between appointments. Some cases can be completed in one visit, while others require multiple appointments.

After root canal therapy, the tooth must be restored to prevent leakage and fracture. Front teeth may sometimes be restored with a filling, while back teeth frequently require a crown because they are exposed to greater chewing forces.

Root canal treatment can relieve pain, control infection, and preserve the natural tooth. Keeping a natural tooth may help maintain chewing efficiency, jawbone stimulation, and normal tooth alignment.

Possible complications include persistent infection, missed canals, instrument fracture, perforation, root fracture, reinfection, or failure of the restoration. Unsuccessful treatment may require root canal retreatment, apical surgery, or extraction.

Temporary discomfort after the procedure is common and may be managed with appropriate pain relief. Severe swelling, increasing pain, fever, or difficulty swallowing should be assessed promptly.

The cost depends on the type of tooth, number of canals, case complexity, specialist involvement, imaging, retreatment needs, and final restoration. Root canal treatment is generally more complex in molars than in front teeth.
