A combination of decreased intake of tap water and the growing popularity of filtered and bottled water and drink sweet tooth that is lethal to prove young and adults.
Stuart Gairns, head of the Executive branch of the Dental Association of WA, Australia says there is a surge in dental caries, partly due to the fact that people who drink a little water taps.
Filtered and bottled water trend which means children lost in the drinking water fluoride, which protected the teeth. As a result, some companies are planning to release the water bottle of fluoride.
Dr. Gairns says even if people are using toothpaste, fluoride in the water is very important because of the fluoride in the water and toothpaste works differently.
"Fluoride in the water is absorbed into the developing tooth enamel," he said. "Fluoride in the toothpaste is surface protection to adults already erupted teeth."
