Root canal treatment is a procedure that involves removing infected pulp from inside a tooth to eliminate infection and prevent future microbial infection. This treatment is typically performed by a specialist dentist who uses precise instruments and techniques, including lasers and microscopes, to ensure optimal results. Root canal treatment is necessary when a tooth’s nerve is affected by decay, infection, or injury, and signs of infection may include pain, discoloration, and sensitivity to hot and cold. During the procedure, the tooth is numbed, and the infected pulp and bacteria are removed using specialized instruments, and the pulp chamber is cleaned and disinfected. The tooth is then sealed with either a permanent or temporary filling, and a crown is typically placed to protect it from further damage. Good oral hygiene practices and regular dental visits are important for maintaining the success of root canal treatment.
