If the tooth that has been filled is broken again, if the cavity is small, you can continue to fill it, or inlay repair, if the pulp is exposed after the need for root canal treatment.
1. Smaller cavities: fillings produce secondary caries or fillings material loosening, shedding, small cavities without clinical symptoms, you can clean up the decay inside the cavity, and then continue to fill the tooth.
2. Inlay Repair: The filled tooth is bad again, the cavity is too big, the defect is located in the neighboring surface of the tooth, which can’t produce the retention force, and it is easy to fall off, so it can be repaired by inlay.
2. Root canal treatment: the filled tooth is broken again, if the cavity defect is too large, after removing the decayed tissue, the pulp has been leaking or the pulp has been necrotic, can not continue to fill the tooth, need root canal treatment and then fill the tooth or full-crown restoration.
If the tooth is broken again, you need to consult your doctor for examination to avoid delays.
