✅ Recommended steps for using whitening strips:
1. Brush your teeth first 🪥 (be gentle). ✔️ Cleaning teeth and removing surface dirt helps whitening ingredients to better reach the tooth surface. ❗ But don't brush too hard to avoid irritating your gums or damaging your tooth enamel.
2. Wait 10–20 minutes before applying the whitening strips. ✔️ Because the enamel surface of teeth may be more sensitive after brushing, and the fluoride in toothpaste also needs some time to be absorbed. ✔️ Waiting a while before applying the teeth whitening strips can reduce irritation and improve the effect.
3. Use teeth whitening strips (usually for 10–30 minutes, follow the instructions). ✔️ Avoid swallowing the ingredients in the teeth whitening strips ✔️ Do not talk, drink water or eat.
4. After peeling off, rinse your mouth with water (or do not rinse, see the instructions for the teeth whitening strips). Some brands recommend leaving the residue to continue working, while others recommend washing it off.
5. Now you can go to sleep 🌙 Avoid eating while sleeping to prevent ruining the whitening effect.
