Shade matching.
Shade is the most frequently remade aspect of anterior work, and very little of it is ceramic error. Most of it happens before the case leaves the practice.
Take it first, not last
Enamel dehydrates within minutes of isolation or sustained opening, becoming lighter and more opaque. A shade taken twenty minutes into an appointment can be a full step off the shade the patient will have once the tooth rehydrates — and the restoration is then permanently too light.
Take the shade and the photographs at the very start of the appointment, before isolation, retraction or extended opening.
If the tooth has already been under a dam, allow it to rehydrate before assessing. This single point resolves more shade problems than anything else.
Assess value first
The eye is far more sensitive to lightness than to hue, which is why a restoration correct in hue and chroma but a step too light stands out immediately.
Judge value by glancing rather than staring, or by squinting — reducing the detail the eye receives makes lightness differences more obvious. Then narrow chroma, then confirm hue.
Look for a few seconds at a time, resting the eye on a neutral grey or blue surface between attempts. The eye fatigues quickly.
Name the guide
A2 means one thing on the VITA classical guide and something else on 3D-Master. Classical is organized by hue family; 3D-Master by value first, which matches the order the eye actually judges in.
Whichever you use, write the guide name alongside the shade every time. It takes two words and removes an entire category of error.
Where the match falls between tabs, say so and name both. That is more informative than rounding to one.
Record the preparation shade
This is the most underrated piece of shade information a practice can send. Translucent materials transmit light, so what lies beneath shows through — a restoration on a bright vital preparation and the same restoration on a dark post-endodontic core will not look the same.
Use a stump-shade guide where you have one, or photograph the prepared tooth directly. The technician needs it before selecting material opacity, not afterwards.
Where the substrate is dark, that may change the material recommendation entirely.
Send photographs
An image containing both the tooth and the shade tab is self-referencing — whatever the lighting did, it did to both. Hold the tab in the same plane as the tooth and immediately beside it, with both in focus.
Photograph the tab you believe matches and one either side. Include the adjacent and contralateral teeth, showing internal character — mamelons, white flecking, incisal halo — which is what makes a restoration read as natural rather than merely correct in shade.
Send images unedited and at full resolution. The photography guide sets out the standard series.
Send the patient for the hardest matches
For a single central beside an intact natural neighbour, a ceramist assessing the patient directly removes every transmission problem at once — no camera, no lighting variation, no processing, no metamerism between operatory and bench.
Fairmont sees patients for colour matching by appointment, arranged through the practice. On a case of that difficulty it is usually the single highest-value step available.
Establish the patient's own preference too. A meaningful proportion want the restoration brighter than the adjacent teeth and would be dissatisfied by a perfect match.

Digital scans and conventional impressions are both accepted. Cases move by UPS and Purolator, and Fairmont works with practices throughout British Columbia and across Canada.
