OBJECTIVES: Tooth fragment reattachment is a conservative approach for treating various types of traumatic dental injuries. This review examines the classification of the traumatic dental injuries, provides a detailed description of the steps involved in fragment reattachment, and discusses the factors influencing its success, along with potential complications. OVERVIEW: Clinicians should be familiar with the types of traumatic dental injuries and their signs and symptoms to establish an accurate diagnosis. Proper hydration of the tooth fragment is essential for optimal reattachment through bonding procedures. Techniques for preparing the fragment and tooth remnant vary in effectiveness, and it is generally accepted that combining adhesive systems with composite resin as the intermediate material is often the most effective option. It is important to discuss the advantages and disadvantages of this treatment option with patients to help them make an informed decision suited to their specific situation. CONCLUSIONS: Tooth fragment reattachment should be considered the preferred technique when the fragment is available and viable. Despite differences in techniques and materials, reattachment appears to show a survival rate comparable to direct composite restorations. Regular and frequent follow-up appointments are essential to monitor for potential complications. CLINICAL SIGNIFICANCE: Tooth fragment reattachment is a conservative treatment option available to patients. Due to significant advancements in adhesive dentistry, fragment reattachment can be offered as a definitive treatment option.
