How do you know if your crown is loose?

You can tell if your dental crown is loose if you experience increased sensitivity to temperature or pressure, if you notice movement when you touch or bite down on the crowned tooth, or if you see any gaps between the crown and the tooth. Additionally, pain or discomfort in the area can indicate that the crown is not securely in place. If you suspect your crown is loose, it's important to consult your dentist for an evaluation.
