The Teeth
Scholars have said that teeth in a dream symbolize the family members, with the upper teeth representing men and the lower teeth women, and each tooth signifying a specific relative. The movement of some teeth may indicate an illness afflicting the person represented by that tooth, while their loss or fall symbolizes their death or prolonged absence. Decay of teeth suggests an affliction befalling the dreamer's relatives, and teeth grinding warns of disputes within the family. Furthermore, plaque, bad odor, or dullness of teeth indicates a fault, bad reputation, or weakness affecting the family, whereas their whiteness and beauty symbolize increased strength, wealth, and status for the family.
