Root canal treatment, often referred to as endodontic therapy, is a dental procedure designed to save a damaged or infected tooth. This treatment becomes necessary when the pulp, the innermost part of the tooth containing nerves and blood vessels, becomes infected or injured due to various reasons, such as deep decay, a cracked tooth, or trauma. The process involves removing the infected or damaged pulp, cleaning and disinfecting the inside of the tooth, and then sealing it to prevent further infection. Root canal treatment not only alleviates the pain and discomfort associated with dental infections but also allows the patient to retain their natural tooth, thus avoiding the need for extraction. While it may be perceived as a complex and intimidating procedure, advancements in dental technology have made root canals more comfortable and efficient, making it a valuable option for preserving oral health and restoring the functionality of the affected tooth.
