Molar is locked, do you need to kill the tooth nerve for correction?

The plan that the doctor you saw yesterday gave you was a restoration plan, not a correction plan: first kill the tooth nerve (pulp) of the mandibular molar, and then unlock the porcelain crown. There are two problems in this treatment: 1, which can't solve your malocclusion and midline deviation.

2. Due to the lack of functional stimulation, alveolar ridge development may be insufficient, and the height required for restoration is not enough, so the tooth shape may be poor.

Correctly, there are many ways to unlock the lock, but you don't have to kill the marrow. The most common method is to open the bite of the upper and lower teeth (that is, to make the upper and lower teeth temporarily unable to bite together), stick something (usually a lingual buckle) on the lingual side of the right lower molar and the buccal side of the right upper molar, and hang a rubber band for a period of time.
