This article reviews the risk factors, clinical diagnosis, symptoms, and treatment strategies for dental erosion in primary dentition, based on current scientific evidence.

✅ Introduction
Dental erosion in primary teeth has become increasingly prevalent due to changes in dietary habits and the growing incidence of systemic conditions associated with acid exposure. Unlike dental caries, erosion results from direct acid attack on enamel and dentin, independent of bacterial metabolism.

Primary teeth are more vulnerable because they exhibit:
▪️ Thinner enamel and dentin
▪️ Lower degree of mineralization
▪️ Higher organic content
▪️ Greater permeability
Untreated erosion may lead to accelerated tooth wear, pulpal complications, and compromised mastication and esthetics.

💬 Discussion
The prevalence of dental erosion in children has increased globally and is closely linked to modern dietary patterns and systemic disorders. Primary teeth are particularly susceptible because of their anatomical and compositional characteristics. The challenge for clinicians lies in differentiating erosion from other non-carious lesions and identifying the underlying cause.
Management should be multidisciplinary, involving pediatricians, gastroenterologists, nutritionists, and pediatric dentists when systemic conditions are suspected. Preventive interventions are highly effective when instituted early, whereas advanced lesions often require restorative rehabilitation.

🎯 Recommendations
▪️ Screen for erosive wear during every pediatric dental examination.
▪️ Record dietary and medical histories systematically.
▪️ Use the BEWE index for standardized assessment.
▪️ Apply fluoride varnish in at-risk children.
▪️ Educate caregivers about acidic beverages and feeding practices.
▪️ Refer children with signs of GERD or recurrent vomiting.
▪️ Schedule regular follow-up visits every 3–6 months.

✍️ Conclusion
Dental erosion in primary teeth is an increasingly recognized condition with significant clinical implications. Because deciduous teeth are structurally more vulnerable, early identification and management are critical. Control of etiologic factors, remineralization strategies, and minimally invasive restorative approaches are the foundation of successful treatment. Preventive education and interdisciplinary care are essential to preserve oral health and function in pediatric patients.
