A patient came asking to correct the central diastema. Some extrinsic stains were found. The central diastema was 2mm, there was no shift in the midline, and the frenal attachment did not interfere with the future emergence of the restoration. Although diastema between the centrals and the laterals were present, the patient only wanted to correct the central one.

Final result with dehydration which makes the teeth look whiter than natural. Shade selection should be performed at the beginning of any restorative procedure.

3 days after rehydration, the teeth look more natural and the gingiva is healthy. Complete rehydration of the tissues can take between 24 and 48 hours.
