Can I just leave the infected tooth if it’s not causing me any pain?
If you ignore an infected or damaged tooth, the infection can spread to other parts of your body. You may want to have the infected tooth extracted if you don’t want to go ahead with the root canal treatment. Although, it is best to keep your natural teeth for as long as possible because if a tooth is missing, neighbouring teeth can drift out of line. Keeping your natural teeth also helps you avoid other treatments, such as implants or bridges.
