Smile
- It is aesthetically pleasing to show a lot of tooth (even some gum) when you are young
- The upper front teeth should follow the contour of the lower lip
- The upper front teeth should not be straight across or in a reverse smile line
- A reverse smile line is when the upper front teeth appear to curve away from the lower lip contour
- The soft tissue of the face, including the upper lip, decends with age & in some older people upper teeth don't show
