Few people want to have their teeth extracted just to look better. But when restoring the teeth is impossible because there is simply not enough tooth structure left, dentures are an alternative.
It is important from a cosmetic standpoint, however, that you need not allow too much time to lag between tooth loss and tooth replacement. Tooth loss causes the face to collapse and the mouth to sink in. At the same time, the nose appears to drop down towards the chin. Deep lines begin to from in the creases of this collapses skin, adding years to the face.
Full dentures can make you look younger because there is almost no limit to what the dentist can create with them.
