Tooth cracks and fractures are one of the leading causes of tooth loss (after caries and periodontal disease). They most often affect upper premolars, molars and lower molars. One of the main predisposing factors for their occurrence are parafunctional habits, which have become more frequent among patients due to an increasingly stressful lifestyle. Once formed, they tend to spread in the dental tissue. Patients come to the dental practice when the first symptoms appear, which can be specific (pain when chewing or releasing a bite and pain in contact with cold and sweet) or very non-specific depending on the condition of the dental pulp and periapical tissue. In addition to a detailed medical history, common diagnostic procedures for suspected tooth cracks or fractures are clinical examination, visualization using magnification, pulp sensitivity tests to thermal stimuli, bite tests, staining, transillumination, and radiological examinations. Establishing a diagnosis can take time due to the non-specificity of symptoms and diagnostic procedures, which over time becomes frustrating, both for the patient, due to the impaired quality of life, and for doctors of dental medicine. Numerous studies have shown that the success of therapeutic procedures is greater if they are carried out earlier. Therapeutic procedures mostly depend on the restorative state of the tooth and the state of the dental pulp and periapical tissue. All therapeutic procedures have the same goal: preventing the progression of tooth cracks and preserving the function of teeth without signs and symptoms of pathological changes in the pulp and periapical tissues. It is important to inform the patient that the prognosis for a tooth with a crack is uncertain and questionable. However, according to recent data from the literature, teeth with cracks have a high survival rate if a timely diagnosis is made and appropriate therapeutic procedures are carried out.
