If the Dentist says tooth cracked because of grinding and not filling he put in 2 weeks ago is this correct?

The dentist's statement cannot be evaluated without further examination and testing. It is possible for a cracked tooth to be caused by grinding or other factors unrelated to the filling. However, it is also possible that the filling itself, or the process of placing the filling, could have contributed to or caused the crack. To accurately determine the cause of the cracked tooth, a dentist would need to perform a thorough examination, which may include taking X-rays, visual inspection, and testing for sensitivity and integrity of the tooth and filling. Without this information, it is not possible to definitively say whether the dentist's statement is correct or not.
