tooth 14 has been sensitive for 8 years since I received a crown. 5 years ago, it was root canaled through the crown and is still sensitive. Now, there is recent decay under the crown. How does the dentist remove a crown which has been subsequently root canaled?

  • Sensitivity for so long in root canal treated tooth can be there because of infection still left in tooth after root canal treatment or in case of poor case selection. Curved canals, resistant bacteria in root canal, overfilling or defective restoration, missed canals etc can lead to root canal treatment failure. If root canal treated tooth is infected, then dentist will remove the crown and will treat the underlying tooth. Re-root canal treatment will be required for the tooth. After re-root canal treatment, you may be requiring new dental crown for the tooth. Prognosis of root canal re-treatment is not as good as root canal treatment done for the first time. If prognosis of re-root canal treatment is poor, then Apicoectomy or tooth extraction is required for the tooth. For more info on problems after dental crown placement, refer to…..
