Thanksgiving is right around the corner. As you and your loved one’s gather at the dinner table, you’ll share stories and swap information, just like the Pilgrims and Native Americans did during the first Thanksgiving. However, hunting and gathering tips probably weren’t the only things they learned from one another. They learned about each other’s oral hygiene methods, too. Although we don’t chew on twigs to keep our teeth clean, early oral hygiene techniques paved the way for modern brushing and flossing habits.
