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. Of all the components of a smile, the teeth play a very important role in creating a perfect effect. It is not just necessary to have good perfect teeth, it is necessary for the teeth 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 today, has made extensive advances in material sciences to be able to alter, reorganize and reposition teeth. Tooth structure can be today added, reduced, moved, altered in terms of color and texture without any deleterious effects and make it look, feel and behave in the same fashion as natural teeth. In fact, in certain situations, the worked on teeth may be able to take on stronger forces than natural teeth.
Nature gives the human body a set of 32 teeth of which there are 28 important working teeth. The four third molars, more commonly known as the wisdom teeth can be discounted. When individuals smile, the teeth most standardly seen in what is known as the “Smile Window” These are the anterior teeth, which could mean the front six to ten teeth. These comprise of one pair of central incisors, lateral incisors, canines and two pairs of premolars. When an individual smiles, this smile window will display these teeth with the upper teeth generally covering about 2/3rd of the lower teeth. Smiles are appealing and aesthetic when certain broad principles are fulfilled. The teeth have to be in the right proportion, they have to be correctly aligned, they have to be of the right shape, the right color and in harmony with the rest of the face.
