Root canal treatment is an excellent solution to save heavily damaged tooth in case the pulp is infected or the extent of the decay is so big, that it cannot be fixed with a filling.
This treatment saves the tooth from extraction and allows the patient to use their natural teeth for longer. Over the course of the treatment the dentist removes the pulp and cleans the root canals thoroughly, then the tooth is sealed with a filling. Thanks to local anesthesia, the treatment is completely painless. After the treatment, the tooth and the surrounding area might be sensitive, which can be managed with painkillers.
