The most important part of smile design is that such procedures are completely personalized. Naturalness is aimed in smile design. This ensures that the person has an aesthetic smile. Color selection, shape, aesthetic appearance and details about the gums are planned according to the characteristics of the person who will have a smile design. People first convey their expectations to the physician. The physician determines a personalized model by planning according to the structure and expectations of the person. Smile design requires not only the skill of a physician but also an aesthetic eye. Teeth and surrounding tissues must be compatible. The most important feature of healthy and natural looking smiles is that they are in accordance with the anatomical structure of the person. Facial features, gender, age, smile symmetry, teeth alignment and stains, as well as the harmony of lips and gums determine the new appearance of the planned tooth.
