Wann ist eine Revision erforderlich?

A tooth has already been root-treated. If germs remained in the tooth, they can later cause chronic or even acute inflammation at the root tip. In the X-ray, we may see that the root treatment has been performed, but there could also be a new or not fully healed old infection. The existing root filling might appear uneven (heterogeneous) or too short in the X-ray. In such cases, bacteria likely remained in the cavities, causing the inflammation. In this case, the old, unsuccessful root treatment must be revised so that the infection can be eliminated. This way, the "time bomb" can be defused, and the tooth can be preserved long-term.

Complications in the healing process may be caused by:

• Curved or narrow canals that were not treated during the initial therapy.
• Complicated, undiscovered, and untreated canals.
• The crown or restoration was not made in time. The seal became leak, and bacteria could now infect the treated tooth interior from the oral cavity.
• Die Krone oder Restauration wurde undicht, wodurch es ebenfalls zu einer erneuten Infektion des Zahnes kommen kann.
