To get rid of a toothache, they had their teeth pulled out. Finally people learned that cleaning their teeth was important, but they didn't have toothpaste right away.
Today there are many toothpaste choices.
Look for one with fluoride , which makes your teeth strong and fights cavities . It's not a good idea to swallow the toothpaste, either, so be sure to rinse and spit. It was only about 100 years ago that someone finally created a minty cream to clean teeth. It was during World War II that brushing became popular. The U.S. Army gave brushes and toothpaste to the soldiers, and they learned to brush twice a day.
