Ancient books clearly pointed out that tooth loss is a symbol of "family loss". Although the author has personal experience, he always avoids using the word "mourning" in the process of dream interpretation. However, what is certain is that dreaming that you have lost your teeth is indeed a harbinger of bad luck. I suggest you pay more attention to the health problems of your parents, relatives and other elders in your family. Maybe the phone you care about can avoid this kind of bad luck.
This explanation is widely circulated and has its own reasons. I suggest that you don't ignore the health of your family.
