Orthodontic treatment risks: Evidence-based prevention strategies

Orthodontic treatment offers significant functional and esthetic benefits; however, it is accompanied by biological and mechanical risks that must be recognized and prevented.This narrative review compiles current evidence on the etiology, prevalence, and management of iatrogenic effects associated with orthodontic therapy.White spot lesions remain the most prevalent enamel complication, primarily resulting from plaque accumulation.Available evidence supports the use of fluoride agents and remineralizing therapies as effective preventive measures.On the other hand pulpal responses are closely related to the magnitude of orthodontic forces; light, biologically compatible forces help maintain pulpal vitality, whereas excessive forces may predispose to inflammation and internal resorption.Periodontal changes-such as gingival enlargement, attachment loss, and alveolar bone alterations-are largely preventable through stringent oral hygiene and controlled biomechanics.Other concerns, including hypersensitivity, external apical root resorption, and post-treatment relapse, require individualized risk assessment and monitoring.Although temporomandibular disorders and material allergies are occasionally reported, current evidence does not confirm a consistent causal relationship with orthodontic treatment.Emphasis on meticulous planning, patient education, material biocompatibility, and structured follow-up can substantially reduce adverse outcomes.Integration of evidence-based principles allows orthodontists to achieve predictable, safe, and esthetic treatment results.
