@Henry Chung: Well, these are the reasons why cracked teeth are a problem. It’s the uncertainty of it all. Although 3 weeks is not nearly long enough. You should definitely wait at least 8 weeks to wee what’s going on. At that point if there’s still symptoms to bite I would just explain to the patient the options of taking a risk and restoring vs. calling it quits and extracting. This is part of the risk management aspect of treating cracked teeth. Good luck!
