What is the hardest substance in the body? Tooth Enamel. What can make the enamel even harder? Fluoride.
Fluoride is absorbed into the enamel and makes it a harder structure. This is beneficial because the plaque, which is bacteria in your mouth, produces acid, which eats away at the enamel surface until it makes a hole in it called “a cavity.”
The harder the enamel, the more difficult it is for the acid to eat a hole in it. Fluoride for teeth is supplied in pill form, in municipal water supplies, in toothpaste, and as a gel or liquid.
Dental offices use higher fluoride-containing gels as a treatment for tooth cleaning visits. Good, hard teeth have a much greater chance of lasting a lifetime.
