A knocked-out tooth, also called an avulsed tooth, is one of the most urgent dental emergencies. Whether caused by a sports injury, a fall, or an accident, having a tooth completely dislodged from its socket can be alarming. In these moments, acting quickly can mean the difference between saving the tooth or losing it permanently. But the big question many people ask is: can you put a knocked-out tooth back in its socket yourself? The answer is yes—sometimes you can—but there are important steps and precautions to follow.
