The dream symbol of a dentures can be ambiguous. It could mean the person you are dreaming about is trying to cover up his or her true personality. It may also be a sign that their condition is poor and they are weak in their character.
The smiling image may indicate that they might have a positive attitude when they wake up, or that they are trying to mask something in their day-to-day life which might cause them shame and negativity.
Dreaming about dentures or wearing false teeth in a dream can symbolize your apprehension or even great embarrassment.
The possible causes of this dream could have something to do with insecurity. The anxiety may have been triggered by an event in your life that you feel uncomfortable being revealed publicly or privately. Or watch how frequently you cover the lower half of your face when whoever talks to you, which might show that there’s a part of yourself that not only hides behind a “mask” but also ridicules itself for hiding.
