Introduction: Lingual gingival recession is an uncommon condition that can lead to dentin hypersensitivity, impaired oral hygiene, and a risk of progression, including root surface exposure, clinical attachment loss, and reduction of keratinized mucosa width. Due to the anatomical complexity of the lingual area, its treatment poses a significant challenge. Currently, there are no standardized surgical protocols specifically designed for this condition, and the literature on the topic remains limited. Objective: To achieve root coverage of lingual gingival recessions using a minimally invasive full-thickness tunneling technique combined with a subepithelial connective tissue graft and coronal advancement of the flap. Case Report: A 35-year-old male patient, ASA I, presented with RT1-type lingual gingival recessions in teeth 33 to 43. The treatment involved a full thickness tunneling technique with a subepithelial connective tissue graft and coronal flap advancement. Complete root coverage was achieved, along with increased gingival thickness and resolution of dentin hypersensitivity. Conclusion: The full-thickness tunneling technique combined with a connective tissue graft represents a safe and effective treatment option for the management of lingual gingival recessions.
