Dentist replaced crown over old root canal tooth - should I just extract it now?

Although a clinical and radiographic study is necessary to determine if it is better to remove the crown, it is always better to try to preserve the natural teeth, being the extraction of the tooth the last option. The conduct to follow in this case, will depend on the diagnosis of the element, if you had decay in the tooth and discomfort, it is likely that the root canal treatment has been affected, however if the tooth has little remaining tooth structure, many times redoing the root canal treatment could worsen the situation. I would now advise watchful waiting and monitor the symptoms to decide whether or not to remove the crown
