Aim: White opacities have always been a major esthetic concern in young patients reporting for dental treatment. We aimed to achieve an esthetic noninvasive immediate correction of these lesions. Background: These discolorations of enamel have a multifactorial etiology and are mainly caused by dental fluorosis, early enamel caries, developmental defects, etc. Conventionally available treatment options for these white opacities include noninvasive and invasive approaches. Recently, a novel “microinvasive” technique has been introduced as an alternative therapeutic technique to manage these opacities esthetically and in a painless way, in a single sitting with no complications. Case description: This paper illustrates the use of resin infiltration to esthetically treat white spot lesions (WSLs) on the anterior maxillary teeth in a 24-year-old female caused due to orthodontic treatment. Conclusion: Resin infiltration can be an effective treatment option for the correction of WSLs on the labial surface of anterior teeth seen after orthodontic treatment. Clinical significance: The resin infiltration technique can be a preferred option for treating superficial WSLs and has a high patient acceptance rate with minimal risk of postoperative sensitivity.
