How to Use Your Cool Teeth Whitening Kit | Official Instructions
Follow these official instructions for the best results, maximum comfort, and safer whitening at home.
- Short, simple steps
- Better tray fit = better whitening
- Use less gel than you think
🦷 Before You Begin
- Brush and floss before whitening
- Start with a short test session
- Use a very small amount of gel
🔥 Step 1 — Mold Your Whitening Trays
Tray Molding Instructions
Water Temperature: 150°F – 160°F (not boiling)
If you don’t have a thermometer:
- Boil water
- Remove from heat
- Wait 6–7 minutes
Molding Steps
- Heat one tray at a time (8–10 seconds)
- Insert trays while still hot — they’re designed to absorb heat and won’t burn your gums
- Suck in air to create a vacuum seal
- Stretch trays toward your molars with your fingers to thin slightly and improve coverage
- Hold 5–8 seconds
- Rinse with cold water to set
- Trim tab & edges if needed
✔ A well-fit tray keeps gel on teeth and away from gums.
Common Tray Molding Mistakes
- Using boiling water → trays warp
- Leaving trays in water too long → loses shape
- Molding both trays at once → poor fit
- Not trimming → discomfort & poor seal
💎 Step 2 — Apply Whitening Gel
How to Apply
- Apply a tiny bead of gel per tooth
- Front 8–9 teeth only
- Maximum 0.25 ml per tray
If gel touches your gums:
- Remove trays
- Wipe gums
- Reapply with less gel
⏱ Step 3 — Whitening Time
- First Session: 2-minute test
- Regular: up to 15 minutes
- Wait 24–48 hours between sessions
- LED light optional
- Do not whiten while sleeping
🪥 After Whitening
- Rinse mouth
- Rinse trays with cold water
- Avoid coffee, tea, wine & staining foods for 36 hours
⚠️ Safety & Sensitivity
- For natural teeth only
- Not for children under 12
- Do not use if pregnant, nursing, or if you have gum disease or cavities
- Stop use if sensitivity lasts over 48 hours
💙 Sensitivity Tip
Mild gum or tooth sensitivity is normal and temporary. A remineralization/desensitizing gel may be used after whitening.
❓ Troubleshooting
- Tray feels loose? Remold
- Gums irritated? Use less gel & trim trays
- No whitening? Tray fit or too much gel usually the problem
