The white material on the teeth after fluoride application is the protective film formed by fluoride on the surface of the teeth, which is a normal phenomenon.
The reason why there is white material after fluoride application is because fluoride is formed after drying and curing on the surface of the teeth to form a protective layer, which is normal and does not need to be cleaned up, and it is necessary to pay attention to the fact that do not eat, drink water, etc. within a short period of time, so as to avoid fluoride from being destroyed, and not achieve the desired effect.
Dental fluoride is mostly used during the development of children’s teeth, appropriate dental fluoride can effectively prevent caries damage, etc. Fluoride can make the teeth stronger, reduce allergies, inhibit the growth of bacteria. However, too much fluoride may cause dental fluorosis, fluorosis and other adverse reactions.
