C D E AMOUNT OF GUM ON DISPLAY A small amount of gum display is acceptable, if your gums are pink and healthy. Your gums can be an indication of healthiness and youth, provided they are not receding, swollen, bleeding or discoloured. An assessment of the relative height of the gum margin and the quantity/quality of the gum tissue is made subconsciously by every person observing your smile - excessive gum display is known as a “gummy smile”, while no gum display is sometimes called a “stiff upper lip”! THE SMILE ARC Th is is defi ned as the relationship of the curvature made by the edges of the upper teeth (the curved red line) with the curvature of the lower lip (the curved blue line). Th e ideal smile arc has the two curves in a close parallel relationship with each other. Careful planning by an orthodontist can allow movement and alignment of the front teeth to create harmony with the lower lip for your ideal smile arc. NEGATIVE SPACE OR BUCCAL CORRIDORS Th is is the small black space visible at the corner of the mouth, which is primarily dependant on the broadness of the smile and the shape of the mouth. Th ese spaces are supposed to be present in all smiles. However, too little or too much can have a signifi cant eff ect on the balance of a smile. OTHER FACTORS THAT CONTRIBUTE TO THE BALANCE OF A SMILE ARE: Upper lip length, lip shape and size and lip animation – these should all be in balance. Th e slope or contour formed by the teeth when you bite together should be straight. If this slope bends to either side, it is considered to be an unattractive or lopsided feature. Th e shapes of the incisors are important - chipped or worn teeth are considered unfavourable. Th e smile and face should be symmetrical and this is judged by matching the midline of your smile and the centre or midline of your face. Dental and facial midlines are not always coincident (in line with each other) but can be considered harmonious if they are close. It is more important for the midline of your upper teeth to be coincident with the facial midline, because this is more noticeable.
