Aesthetic dentistry examines the details that create harmony in the face and smile and seeks to answer the question, "What else could these teeth naturally have looked like?" When the answer is applied correctly, the result is a pleasant appearance that complements facial expression without interfering with eye contact while speaking. Many factors are considered, including the color, translucency, surface texture, shape, size, angles, relationships between the teeth, proportions, gum levels, and smile line, and all treatments are carried out according to these criteria.
