SANS EFFORT- Exhibition of delicate caries curing technique ( From the National Library of Medicine, Bethesda, Maryland )

Long ago dentists determined that the loss of teeth was due to tooth decay caused by the destruction of toothe enamel from acids, resulting in bacterial invasion of the pulp through the broken barrier.

Not too far wrong(!)

But if Dentistry ever discovers a way to prevent all tooth decay, the job of saving teeth will be less than half done- because more teeth are lost from gum irritation, inflammation and recession, than from tooth decay.
