What if you don't have a root canal done?

If you don't have a root canal done when it's needed, the infection or damage to the tooth can worsen, leading to increased pain and swelling. The tooth may eventually abscess, which can cause further complications such as spreading the infection to surrounding tissues or even systemic issues. Ultimately, the tooth may become non-viable and require extraction. Ignoring the problem can also result in more extensive and costly dental treatments later on.
