White spot lesions (WSLs) are common post-orthodontic complications that could be attributed to the lack of oral hygiene with fixed orthodontic appliances. Resin infiltration (RI) technique is an increasingly popular, minimally invasive restorative treatment option that involves penetration of a resin into the body of the WSLs. In this case report, the clinical application method, difficulties during application and long-term evidences of RI technique were described. Sixteen-years-old girl referred to our clinic with WSLs on her maxillary and mandibular anterior teeth following orthodontic treatment.
