1. Use the shade reference chart to check and mark your current tooth shade.

2. Rinse the LED mouthpiece with water. 

3. Brush your teeth.

4. Take off the seal of the SmileZero Gel syringe. Apply a total of 1,5 ml of gel over the upper and lower rows of LED lights of the mouthpiece. Reapply the seal of the syringe.

5. Connect the LED mouthpiece with your power source (phone or power bank).

6. Put the LED mouthpiece into your mouth and gently bite on to it in order to keep it in place and so that the gel can evenly disperse.

7. Keep the LED mouthpiece in your mouth for 20 minutes and watch TV, read a book or listen to your favourite music!

8. At the end of the treatment, remove the mouthpiece and rinse your teeth with water.

9. Rinse the LED mouthpiece with water and let it dry.

10. Keep the SmileZero Gel syringe and the LED mouthpiece in your qsmile pouch. Store in a cool and dry place.

11. After using qsmile for 5 consecutive days, compare your tooth shade with the shade you previously marked on the reference chart in order to check your improvement.

Once you notice that your tooth shade gets darker again you can repeat the five day treatment.
