Apparently, the ingredients in plastics and fungicides may affect dental health in kids. The harm done is most likely to manifest itself in the long term.
The chemicals found in polymers and fungi-killing medicinal agents may adversely affect the dental health of children. This is due to an imbalance in the hormonal status of the kids.

Exposure to these hormonal disruptors are definitely not good for young tykes. The hormones of mammals are especially sensitive to these hormonal disturbances from certain chemicals in the environment.
BPA is one such hormone disruptor. It is found in ordinary stuff such as refill bottles and food storage boxes. Another similar chemical hormone that messes with the hormones is Vinclozolin and it is found in fungicides.
These chemical agents are commonly employed in vineyards, golf links and fruit gardens. The problem is that a disease known as molar incisor hypermineralisation (MIH) affects 18% of children that are at a prepubescent stage of their lives. In this malady, the first molars and incisors tend to develop highly weak parts that turn painful and also form cavities in the future.
Dental enamel is the exact spot where these sensitive spots develop in the first place. This is the layer that protects the teeth from all sorts of harmful effects.
However, while bones heal and even show some degree of re-growth, dental enamel once damaged is gone forever leaving the teeth at the mercy of the environment.
Studies on rodents in the lab show that exposure to BPA causes MIH. However, the exact nature of the mechanism through which this harm is done is not fully known by scientists.
Rodents in labs had their dental enamel ruined thanks to doses of BPA. Whether this is so in humans is a sort of guesstimate that will take a leap of faith on a scientific level.
Daily doses of both BPA and Vinclozolin were administered to rodents. After samples were collected from the teeth of the rodents, it was found that two genes in the rodents were changed.
These genes controlled the mineral content of the teeth. The second part of the experiment involved doses of estrogen and testosterone being given to the rats.

The ameloblast cells were examined under the microscope. The hormones increased the dental enamel in the rodents. Tooth enamel is thus helped along in its growth by certain hormones and destroyed by other hormonal disruptors.
