How Are Custom Grillz Made? From Mold to Polish

Custom grillz are made through a precise multi-step process that converts an exact mold of your teeth into solid gold or sterling silver jewelry. From initial dental impression and wax carving to lost-wax investment casting, hand-setting stones, and high-shine polishing, crafting custom dental jewelry requires traditional goldsmith techniques combined with dental precision. Here is how a custom grill goes from a simple putty mold to a finished piece that snaps flush onto your smile.

Step 1: Taking an Exact Impression of Your Teeth

The foundation of every custom fit starts with an accurate dental impression. Unlike cheap pre-made grillz that use bending metal strips, custom grillz require a 3D impression of your exact tooth contours. You can take this impression at home using our easy-to-use mold kit or stop by our Renton studio for an in-person appointment. The putty mixes together, sets in a dental tray over your teeth in about two minutes, and creates a clean imprint of your bite line.

Step 2: Design Selection and Wax Modeling

Once we have your teeth mold, we sculpt a custom wax model of your grill. After pouring a hard dental stone cast into your impression, our bench jewelers carve a wax replica directly over the stone teeth. During this stage, you choose your style and specifications:

• Metal choice: Select solid sterling silver, 10K gold for ultimate durability, or 14K gold for a rich warm tone. (Read our 10K vs 14K gold guide to see which karat fits your budget.)
• Grill design: Choose between full solid caps, deep-cut fangs, or sleek open face outlines. (Check our open face vs solid gold breakdown for design ideas.)
• Stone accents: Plan placement for moissanite or VVS diamonds if you want an iced-out finish.

Step 3: Casting in Solid Gold or Silver

We use the lost-wax investment casting method to turn wax into real precious metal. The wax model is attached to a sprue base and encased in a heat-resistant ceramic flask called investment material. The flask goes into a high-temperature kiln where the wax burns out completely, leaving an empty cavity in the exact shape of your grill. Liquid 10K gold, 14K gold, or sterling silver is poured into the cavity under vacuum pressure, filling every microscopic detail of your tooth mold.

Step 4: Stone Setting, Hand Polishing, and Final Fit

Hand craftsmanship turns raw cast metal into mirror-polished jewelry. Once cooled, the metal piece is freed from the investment mold and carefully hand-finished:

• Sprue removal and grinding: Excess metal sprues are cut off and ground flush with specialized jeweler burs.
• Stone setting: If you requested iced accents, our master setters hand-drill micro-pave seats and secure each stone individually.
• Mirror polishing: Multiple grades of polishing compounds give the metal a flawless, high-shine finish.
• Fitting check: The finished grill is fitted back onto the original stone teeth model to verify suction, margin comfort, and seating flushness.

FAQ

How long does it take to make custom grillz? Standard production takes 1 to 3 weeks from the day we receive your approved impression kit, depending on design complexity and stone setting work.

Can I take my own impression at home? Yes. Our remote at-home mold kits include dental putty, upper and lower trays, and clear step-by-step instructions so you can take a reliable impression without visiting a dentist.

What metals are used to make custom grillz? We craft custom grillz exclusively in real, solid precious metals: sterling silver, 10K gold, and 14K gold. We never use base metals, nickel alloys, or cheap gold plating for custom work.

How do custom grillz stay on your teeth without glue or adhesive? Custom grillz hold securely through a combination of light friction and suction against the natural contours of your teeth. Because the metal is cast from your exact mold, it snaps on snugly without chemical adhesives.

How much does it cost to make a custom grill? Custom grillz start at $157 for a single tooth in sterling silver and scale up based on gold karat, tooth count, and diamond work, running up to $34,997 for fully iced-out double-arch pieces.
