Root canal therapy is a procedure that many patients respond well to. Many of them experience a successful procedure, in fact, where their tooth is saved and able to be restored to health. Unfortunately, this is not always a guarantee. We are not able to tell you with 100% certainty that a root canal can save your tooth, but it is very, very likely that it could. The important thing to keep in mind is that you will need to have a crown installed within 30 days of your root canal in order to ensure that the root canal was not wasted and that the tooth is protected from further damage or decay.
