Dream about dentist office stands for the things that drives and motivates you. You are erasing the past and starting anew. You don't care what others think of you. The dream hints a person who you view as cold-blooded, fearful, or thick-skinned. You are biased about some situation.
Dentist office denotes your own state of thinking wisely and the struggles to make a decision
You have not digested or accepted some messages. You are experiencing feelings of aggression. The dream is unfortunately an aspect of yourself that has died. There is something that you need to get out of your head.
