White Fillings are a type of plastic called composite. We find that, and research supports this, white fillings in baby teeth tend to leak and do not last for the life span of the baby tooth. So for instance, in a child who is 3 years old who has a cavity and were we to place a white filling in that tooth, that child may need to have it replaced again at 5 years old and 7 years old and 8 years old until that tooth finally falls out. If the child is struggling with treatment at the dental office then this is not the best option for them. We much prefer to place sliver fillings or amalgam as they have superior longevity, lasting twice or three times as long as a white filling.
