“Smile” should give confidence to beholder and pleasant emotions to viewer.
Through various patients experience I can say there are certain rules for smiling teeth and face. Ideal smile includes:
1. Beautiful smile should be healthy which include health of teeth, gums, dental bone and lip. Face profile should be straight
2. Measure length and width of the face, a beautiful person face is about 1.5 times longer than it is wide.
3. In rest position 2 to 3 mm of upper teeth should be visible and while smiling upper teeth gum line should be visible. More than 2 mm of visible gum lead to gummy smile.
4. Color of teeth should be milky white, not exactly white
5. Length, width and contour of teeth vary with facial length and width, should be proportionate to it
6. Smile Arc describes how the biting edges of the upper teeth follow the curvature of the lower lip line.
When this arc is present, smiles are called ‘consonant’ and look more esthetic Best smiles are god gifted but in some cases we need correction.
Artificially we can create beautiful healthy smile by veneers, cap, tooth color fillings, invisible braces, aligners, gum and jaw treatment or doing some minor changes in teeth. Even we can guide erupting teeth in childhood with guiding appliances.
