The hardest color to get honestly right.
Full-arch zirconia gave dental labs a new job: building gum tissue in ceramic. CGI's red gum stains are manufactured in the USA, cadmium-free — vivid color you can trust against soft tissue.
Full-arch zirconia changed what a dental lab is asked to build. Suddenly technicians weren't just shading teeth — they were recreating gum tissue in ceramic, which means the vivid reds of gingival shading matter more than ever. CGI makes those reds in the USA, without cadmium.
A recent shiftWhy red entered the picture
For most of dentistry's history, a ceramist's palette barely needed deep reds. Crowns and bridges were about teeth — whites, creams, ambers, the occasional incisal blue. The intense reds and pinks of gingival shading simply weren't in heavy demand.
That changed only a few years ago, with the rise of full-arch monolithic zirconia restorations — the implant-supported, Toronto-bridge–style prostheses that replace an entire arch. These restorations don't just rebuild teeth; they rebuild the gum line. To look natural, the gingival portion has to be shaded in living tissue tones, from pale pink at the margins to deep, saturated red between the teeth. That demand for vivid red gum stains is what makes the chemistry behind those reds worth paying attention to.
A heavy metal classified as a human carcinogen. Long-term exposure is linked to damage to the kidneys and bones and interference with how the body processes calcium. It's a material with no place in something that sits against soft tissue for years — which is why CGI keeps it out of its red gum stains entirely.
Why red is the demanding color
Greens, blues, browns, and the warm tooth shades are easy to source from stable, benign oxides. Red is different. Achieving a brilliant, saturated red that survives the heat of firing without graying out is one of the hardest problems in ceramic pigment chemistry — and gingival shading needs exactly that kind of red.
Getting there cleanly takes deliberate engineering. CGI's answer is to deliver those deep gingival reds through carefully chosen, cadmium-free pigment chemistry — vivid color, made without compromise, in a restoration that sits against soft tissue all day for years.
Vivid gingival red and a clean composition shouldn't be a trade-off — CGI makes both, in the USA.
The CGI answerRed gum stains, made without cadmium
CGI engineered its gum stains to deliver deep, tissue-true reds entirely without cadmium — selecting and stabilizing pigment chemistry that holds its chroma through firing instead of graying out. Every shade is formulated and manufactured in the USA, so the color and the composition are both accounted for.
The result is a gingival palette built for the full-arch era: warm, living reds and pinks that read as real tissue, formulated so the color you trust is also a color you don't have to second-guess.

Why technicians should care
-
✓Cleaner peace of mindRed gum stains with no cadmium mean one fewer heavy metal in the tissue that sits against a patient's gums for years.
-
✓Color that holds through firingStabilized red pigments keep their chroma through the bake, so your gingival shade looks the same coming out of the oven as it did going in.
-
✓Built for full-arch workA gingival palette tuned for exactly the restorations that made deep red gum tones essential.
-
✓Made in the USA, documentedCGI formulates and manufactures domestically, with traceable product documentation behind every shade.
The right red, the right way
Full-arch zirconia gave the profession something genuinely new — and with it, a new demand for vivid red gum shading. CGI's commitment is straightforward: deliver those reds beautifully, manufacture them in the USA, and keep cadmium out entirely. That's the standard behind CGI's red gum stains, and it's why the gingival color you choose is one you never have to second-guess.
Reds worth trusting.
