2. Detailed Steps to Making Your Mold Impression.

STEP 1: PREPARATION ⏱️ Ready in 1 Minute

Brush Teeth and Wash Hands

Brush your teeth and wash your hands thoroughly to remove oils.

STEP 2: KNEADING, ROLLING AND SPREADING PUTTY INTO TRAY ⏱️ 45 Seconds Max

Knead Putties, Roll Cylinder & Spread Into Tray

Open one colored base jar and one white catalyst jar. Combine both putties in your hands and knead them together rapidly with your fingertips for 20 to 30 seconds. Roll the blended putty between your palms into a smooth 3-inch cylinder (like a small hot dog). Place the putty into the tray channel, pressing it gently to fill the curved space evenly from molar to molar.

Step-by-Step Putty & Tray Preparation
Follow this quick 4-step sequence before seating the tray against your teeth
1 Take Putties Out
Step 1: Take Putties Out

Open 1 colored base jar and 1 white catalyst jar

2 Knead Rapidly (30s)
Step 2: Knead Rapidly

Knead firmly until putty is one uniform color with zero white streaks.

3 Roll 3-Inch Cylinder
Step 3: Roll 3-Inch Cylinder

Roll between palms into a smooth sausage log curved like a U.

4 Load Evenly in Tray
Step 4: Load Evenly in Tray

Press into tray channel, keeping slightly more putty at the front.

⚠️ IMPORTANT: Work quickly. The putty must be completely solid in color with no white marbling. Once blended, you have roughly 45 seconds before it begins to cure.
STEP 3: TAKING YOUR IMPRESSION & REMOVING TRAY ⏱️ 3.5 Minutes Curing Time | ⚠️ DO NOT BITE

Take Your Impression & Release Tray

Please read the section below that pertains to the grillz you ordered. For Upper Grillz read Upper Impression, for Lower Grillz read Lower Impression, and for a Full Set read BOTH.

⚠️ THE #1 CRITICAL RULE: DO NOT BITE DOWN WITH YOUR TEETH! Always use your thumbs and fingers to push the tray into position. Biting down with your jaws forces your teeth all the way through the putty until they hit the hard plastic tray base. This cuts through the mold, distorts tooth tips, and prevents your grillz from seating properly.
Upper Impression

Upper Teeth Impression Guide

Solid Palate Tray

2 Push Up With Thumb
3 Center & Wrap Lips
4 Wait for 3.5 Minutes
1
Align Find the center notch of the upper tray and line up your two upper center front teeth with that space.
2
Push Up with Your Thumbs Push your tray straight UP into your upper teeth using your thumbs placed near the molars on each side. Press with firm, even pressure until the putty completely covers your gumline. Stop just before the tips of your teeth touch the hard plastic tray base. ⚠️ DO NOT BITE DOWN! Use your thumbs and press upward.
3
Center & Wrap Lips Ensure both the left and right sides of your teeth are pushed evenly into the putty. Gently pull your upper lip up and out over the front outer edge of the tray.
4
Set Timer for 3.5 Minutes (210 Seconds) As you wait for the putty to harden, you may rest your jaw and gently close your mouth around the tray handle, but do not clench your teeth or apply biting pressure. If you clench, the putty shifts and becomes distorted. Keep your mouth completely still without talking.
5
Test & Remove Tray Press your fingernail against the excess putty—it must feel completely firm and rubbery like an eraser. If still soft or mushy, wait another 30–40 seconds. Once fully set, grip the tray handle firmly and slowly pull straight DOWNWARD in one smooth, vertical motion to release the seal. Do not wiggle side-to-side.
Lower Impression

2 Push Up With Thumb
3 Center & Wrap Lips
4 Wait for 3.5 Minutes
1
Align Find the center notch of the lower tray and line up your two lower center front teeth with that space.
2
Press Down with Thumbs / Fingers Press the tray straight DOWN into your lower teeth using your thumbs or index fingers along both sides. Press firmly until the putty completely immerses your teeth and covers your lower gumline. Stop before teeth touch the plastic tray base. ⚠️ DO NOT BITE DOWN with your upper teeth! Use your fingers and press downward.
3
Center & Wrap Lips Ensure both left and right sides of your teeth are pressed evenly into the putty. Pull your lower lip down and then up over the front outer edge of the tray.
4
Set Timer for 3.5 Minutes (210 Seconds) Rest your jaw and close your mouth gently around the tray. Do not clench, swallow forcefully, or talk. Removing the tray too early will warp the impression; keeping completely still guarantees a sharp, accurate impression.
5
Test & Remove Tray Press your fingernail against the putty to confirm it has fully hardened. Once firm, grip the tray handle firmly and slowly lift straight UPWARD in one smooth motion to release the suction seal without twisting or bending the mold.
⚠️ REMINDER: DO NOT REMOVE THE MOLD IMPRESSION FROM THE PLASTIC TRAY The hardened silicone mold must stay firmly locked into the tray perforations. Never peel or pull the putty out of the tray. Rinse your finished impression with cold water, let it air dry, and proceed to the quality scorecard below.

3. Quality Scorecard: What Makes an Approved Mold?

Before packing your mold into the return envelope, inspect it against our master lab checklist:

✓

Approved Mold (Ready to Cast)

Approved dental mold impression ready to cast
  • Deep 3D Impressions: Every tooth is clearly delineated from incisal edge to gum.
  • Visible Gumline: 2mm to 3mm of clear gum tissue is imprinted above the teeth.
  • No Exposed Tray: Putty forms a thick, solid cushion between teeth and plastic.
  • Uniform Color: Zero white streaks or unmixed marbling.
✗

Rejected Mold (Needs Remake)

  • Bitten Through: Teeth cut straight through putty to the hard tray bottom.
  • Missing Gumline: Impression stops midway up teeth with no gum border.
  • Double Drag / Slanted: Patient moved while setting, creating blurry double edges.
  • Streaky Putty: Putty was not kneaded into a single solid color.

Frequently Asked Questions About Impressions

What if I have crooked, rotated, or missing teeth?
The dental putty molds around any tooth anatomy, including gaps, crowding, rotations, or missing teeth. For missiing teeth, indicate which teeth is missing and we will fill in the gap with extra material so it looks like the grillz looks like it is cover a real teeth.
Can I do the impression if I have permanent bonded retainers or Invisalign attachments?
If you have a permanent wire retainer behind your front teeth, you can still take an impression safely, as the putty will capture the front surface and the retention clips will be calibrated accordingly. If you wear removable clear aligners (Invisalign), simply take them out before making your impression.
What if I mess up both sets of putty included in my kit?
Every custom grillz order is backed by our Fit Guarantee. If your mold is not approved, we will mail you a free replacement impression kit.
How long does turnaround take once I mail my mold back?
Return shipping typically takes 3 to 6 business days. Once our lab receives your mold, our jewelers pour the stone cast, wax the design, cast your solid gold or silver, and hand-polish the piece in 10 to 18 business days before shipping your finished grillz back to you with tracking.
