Losing teeth in a dream is both very common and very vivid. Teeth crumble, loosen or fall into your hand, and you wake relieved to find them in place.
Interpretations vary. Some readers connect teeth with appearance and how others see us. Others link them to speech, since teeth shape what we say, or to age and change. Folk traditions in several cultures attach their own meanings, and these differ so much that no single reading can be called correct.
Look at the details. Teeth falling out differs from crumbling teeth, where the loss is slow and out of your hands. Pain, blood and embarrassment each point somewhere different.
Some people notice these dreams when they are worried about something concrete, such as an event or a conversation. If you grind your teeth in your sleep or have dental pain, a dentist is the right person to ask.
Ask yourself: what felt at risk of coming loose in the days before?
