Ingredients needed:
- 1 teaspoon (about 5 g) of fluoride toothpaste
- A few drops of fresh lemon juice (about 1 ml)
Preparation and application:
- In a small container, mix the toothpaste and lemon juice until you get a smooth paste.
- Apply this paste with a soft toothbrush, without rubbing too vigorously.
- Leave on for a maximum of 1 minute. This short period of time is enough to take effect without risking erosion.
- Rinse thoroughly with clean water.
