Hello Tuesday what a day I am having so restless and hot and not knowing what I am doing but being Tuesday it is tough stuff day.
Today's tough stuff is tooth enamel something all of us have for some of if not all of our lives.
Human tooth enamel is The hardest substance in the body. It forms in a thin layer over our teeth to give them strength and protection when we bite and chew.
Like bones it contains a lot of calcium and other minerals, if you tap your teeth you'll find the hard shiny enamel surface.
Although very strong enamel can be damaged by acid, which eats away at it making holes in the teeth. Bacteria that live on your teeth make acid when they feed on sugary food.
Brushing your teeth washes them away and protects the enamel.
Human tooth enamel, though isn't the hardest of all, Beavers, which like gnawing down trees have even harder ename; that contains a lot of iron.
The hardest material in the animal world is the enamel like substance that limpets teeth are made of.
When you exhume the body the teeth are left and so are the bones and hair.

ReplyDeleteDearest Jo-Anne,
ReplyDeleteWho would have guessed that those limpets (acquatic snails) do have the hardest enamel on their teeth?!
