A smile is something that bridges the large gap between any two individuals. In fact a pretty smile can disarm the strongest of opponents in any argument. The teeth play a very important role in creating a perfect smile. It is necessary to have good set of teeth and to be in harmony with the face, the lip line, the curvature of the mouth, etc. The same size and shape of teeth in one smile would look very aesthetic, while in another, they would not. Dentistry is able to alter, reorganize and reposition teeth and the tooth structure can be altered in terms of color, position size and texture without any harmful effects and make it look, feel and behave in the same fashion as natural teeth.
The human body is given a set of 32 teeth of which 28 are the most important working teeth. The four third molars, more commonly known as the wisdom teeth can be discounted. When a person smiles, the teeth are seen in what is called as a “Smile Window”. These are the front 6 to 10 teeth which are also known as the anterior teeth. These comprise of one pair of central incisors, lateral incisors, canines and two pairs of premolars. The smile window displays these teeth with the upper teeth generally covering about 2/3rd of the lower teeth. In order for your smile to be appealing and aesthetic, the teeth have to be in the right proportion and correctly aligned. They need to be of the right shape and color in harmony with the rest of the face.
The factors that mainly influence smile design are :
Your facial shape. For example, a long face may need to accentuate width to appear more oval. Someone with attractive features in the center of the face may need bold central incisors to draw attention to that center.
Your image aspirations. How do you want to appear to others? A sophisticated smile gives the appearance of more intelligence, maturity and judgment. A sexy smile gives the appearance of more warmth, energy and boldness
Your age, or how old you want to appear. Longer central incisors make you appear younger. Also, whiter teeth make you appear younger. Conversely, a flatter smile or a more subdued color to the teeth make you appear more mature.
Along with the teeth, the gums, technically known as the gingiva also play a significant role. There is certain proportion of pink to white, which has to be maintained for the smile to be pleasing and beautiful. At times, the only difference between an excellent smile and a run of the mill smile can be heavily pigmented gums. If there is discrepancy in any of the above listed factors, the smile tends to get unaesthetic. It is not that if any one of the above conditions is not met, the looks will be totally hampered. Many a time, totally out of position teeth or disproportionate teeth may still exhibit a very pleasing smile. When the smile does get unaesthetic, the dentist can play a large role in correcting these discrepancies.
