After the root canal is completely filled, it follows one last step - The tight seal of the canal entrance.
Failures in endodontics are often due to inadequate sealing of the root canal orifices. If we allow bacteria to penetrate into the tooth again, even the best obturation method can't prevent a reinfection. Therefore it is absolutely necessary to renew leaking fillings or crowns.
This video shows an example.
To create an additional barrier to bacteria, the entrance to the root canal is sealed with a flowable resin (composite). The tooth is finally reconstructed with a solid composite filling.
