One of the first things we will notice while communicating with others is a smile. Nowadays, when the concept of beauty is present all around us, more and more people want to beautify their teeth in order to build greater self-confidence and a sense of social affirmation. Tooth restorations with direct composite fillings have proven to be an acceptable method of choice in aesthetic corrections. One of the indications for the use of composite fillings on the anterior teeth are also modifications of the tooth shape and size after orthodontic therapy. In cases of pegged teeth or when other teeth are translated to the position of the teeth that are missing due to congenital deficiency or trauma loss, orthodontic treatment should be accompanied by restorative procedures to achieve a beautiful smile. In order for clinicians to be able to create aesthetically superior works, it is essential to know what to observe during the clinical examination, what the desirable tooth shape is, ideal tooth proportions, how to prepare the cavity, which technique to use and how, which material to choose, how to apply materials and how to finish a restoration. Four cases are presented in this paper, three of which are corrections of appearance after orthodontic therapy. In the fourth case, non-aesthetic composite filings on the central incisors were replaced. The fillings were made by polychromatic composite layering. It was concluded that superior aesthetic results can be achieved with composite fillings.
