Teeth as a topic of dreams is more common than we think because teeth is associated with our very emotions. With every smile or frown, we see teeth or it is hidden away.
Also, when we were younger, we all went through the traumatic experience of losing our baby teeth and replaced with deeply rooted teeth. Though we don’t know it, but the experience of having missing teeth was an embarrassing and awkward moment of life that no one can control.
As an adult and dreaming of rotten teeth or falling teeth, there are deeper issues that trouble you in the form of potential embarrassment that keeps you from addressing important issues at hand.
