How do I take a shade photo for a crown?

Timing matters more than most clinicians expect. Take the shade photo before preparation, on a hydrated tooth. Desiccation from isolation or air-drying shifts the apparent value within 10 minutes, sometimes by two full shade steps. The adjacent tooth is your reference, not the preparation stump. One shot at the gingival third, one at the incisal edge, and one full-facial view gives the ceramist the layering map needed to match both the body and the translucency zone.

Lighting is the most common failure point. Flash photography flattens value and saturates chroma, producing a photo that reads lighter than the tooth actually is. Diffused operatory lighting or a ring light set to 5500 K gives a truer read. Set your camera or intraoral camera to a fixed white balance rather than auto, and keep that setting consistent across every case you send. The lab cannot correct for a white-balance drift that shifts case to case.

For anterior cases at Dani Dental, the ceramist assigned to your case reviews every photo submitted and will flag within four business hours if the image set is insufficient to proceed. That step prevents remakes caused by shade ambiguity, which is one of the top three reasons single-unit anterior cases come back. Including the shade tab label in the frame lets the technician cross-reference against the Vita or Ivoclar system without guessing which tab family you used.
