- The patient expressed satisfaction with the final aesthetic outcome.

## Abstract

Peg-shaped lateral incisors are the most prevalent tooth size discrepancy, which can have a number of functional and aesthetic implications in affected people. This case report presents a conservative treatment approach to treat bilateral peg laterals and restore aesthetic harmony. A 21-year-old male patient complained about the shape and unaesthetic appearance of his two front teeth which negatively impacted his smile. The patient presented with bilateral peg laterals in the maxillary arch, and he had a stable occlusion with normal overjet and overlap and good periodontal health. Digital smile design (DSD) analysis revealed a discrepancy in crown width between Teeth #13 and #23 and gingival height discrepancy between Teeth #11 and #21, and #12 and #22. Accordingly, it was planned to perform a crown lengthening procedure to overcome the gingival height discrepancy of Teeth #12 and #21, place a full-contour resin composite restoration on Teeth #12 and # 22 and increase the mesiodistal width of Tooth #13. The patient underwent home teeth whitening for 2 weeks, followed by a 1-week observation period to ensure colour stability of the tooth. Laser gingivectomy was performed to correct the gingival height discrepancy, and incremental resin composite was used to restore the peg-shaped laterals. The restoration was contoured, finished and polished to obtain a smooth and glossy finish. The aesthetic treatment achieved excellent results, and the patient was pleased and excited with his new smile.
