So apparently, many people have dreams that have to do with teeth falling out or suddenly crumbling or getting really crooked really easily.
I googled the meaning of such dreams. I'm really bored. Anyway according to dreammoods.com having dreams about teeth can show a potential anxiety about your appearance or how people perceive you. Or the whole "my teeth are falling out" dream can have a connection of being embarrassed or even the loss of power a person may fall victim to after losing said teeth.
I am not satisfied with this.
