The objective of this manuscript was to review the literature on dental trauma splints and discuss materials used for splinting injured teeth in terms of their properties and conditions that are required for optimal stabilization. A literature search was conducted in the PubMed database with the keywords: “trauma splints”, “dental trauma” and “traumatic dental injuries”. The search was limited to English language publications. 42 publications fulfilled the inclusion criteria and were in accordance with the current recommendations. Optimal splinting of the teeth after trauma is one of the main predictors for pulpal and periodontal healing. The splints stabilize and protect the teeth, creating favorable conditions for the regeneration of the supporting tissues. Their application and removal should be easy and fast without any additional irritating of the surrounding tissues. The materials used to stabilize the injured teeth should keep the tooth in the original position, allowing for its physiological mobility.
