Final answer:
Jewelry, contact lenses, and dental fillings need to be removed prior to fluoride treatment.
Step-by-step explanation:
Before fluoride treatment, the following items need to be removed:
- Jewelry
- Contact lenses
- Dental fillings
This is because fluoride can react with certain materials, such as metals and contact lenses, and may damage or discolor them. Dental fillings, particularly those made of amalgam, can also be affected by fluoride treatment.
