A perfect smile is as unique as the person that it belongs to, so achieving the perfect smile requires personalized attention, an understanding of facial and dental aesthetics and the ability to design and create it. In the perfect smile, there is harmony between the smile, facial form and the personality of each patient. Skilled cosmetic dentists strive to achieve an aesthetically pleasing balance when creating the perfect smile.
The size and shape of the lips, gums, teeth and face are all involved when creating a perfect smile. Attractive ratios are the most importance. The width of the smile should be at least half the width of the face. The upper and lower lips should be symmetrical on either side of the mid-line of the face. The top teeth should be dominant, and a small portion of the bottom teeth should show. All of the visible teeth should be straight.
A bright, white smile is great, as long as the smile looks completely natural and, the gums should be pink, which is how healthy gums look naturally.
