A root-canal treatment is applied to save your tooth. But sometimes the damage is too deep or the tooth enamel is too fragile to withstand the procedure. These factors can cause tooth loss. Another risk is abscess formation in the root of the tooth if some of the infected material is left behind or antibiotics are not effective. If you are concerned about a root canal, you can talk to your dentist about an extraction instead. In some cases, other treatments may be preferred instead of the root canal. These treatments usually involve placing a partial denture, bridge or implant in place of the damaged tooth.
