Cracked tooth

It is impossible to repair it slowly, and there is a crack. If it has split in half and is loose, consider pulling it out. If after a week of root canal treatment, weakness and slight pain appear, it may be a normal drug reaction, and it will be better in a few days. The safest way to stop the pain is to protect the teeth with braces (porcelain teeth) so that they won't crack again in the future. It is really unsatisfactory after treatment, so consider pulling it out.
