Before Toothpaste Was Invented We're lucky that we know so much now about taking care of our teeth. Long ago, as people got older, their teeth would rot away and be very painful. 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. While you're swishing that minty-fresh paste around your mouth, think about what people used long ago to clean teeth: • ground-up chalk or charcoal • lemon juice • ashes (you know, the stuff that's left over after a fire) • tobacco and honey mixed together It was only about 100 years ago that someone finally created a minty cream to clean teeth. Not long after that, the toothpaste tube was invented, so people could squeeze the paste right onto the toothbrush! Tooth brushing became popular during World War II. The U.S. Army gave brushes and toothpaste to all soldiers, and they learned to brush twice a day. Back then, toothpaste tubes were made of metal; today they're made of soft plastic and are much easier to squeeze! Today there are plenty of toothpaste choices: lots of colors and flavors to choose from, and some brands are made just for kids. People with great-looking teeth advertise toothtpaste on TV commercials and in magazines. When you're choosing a toothpaste, make sure it contains fluoride. Fluoride makes your teeth strong and protects them from cavities. When you brush, you don't need a lot of toothpaste: just squeeze out a bit the size of a pea. It's not a good idea to swallow the toothpaste, either, so be sure to rinse and spit after brushing.

История зубной пасты

Раньше люди страдали от зубной боли и потери зубов. Чистка зубов была важна, но зубной пасты не было. Для чистки зубов использовали:

  • измельченный мел или уголь
  • лимонный сок
  • пепел (остатки после пожара)
  • смесь табака и меда

Примерно 100 лет назад появилась первая зубная паста в виде крема, а затем и тюбик, что сделало чистку зубов более удобной. Во время Второй мировой войны зубная паста и щетки выдавались солдатам. Современные тюбики сделаны из пластика.

Сегодня существует множество видов зубных паст. Важно выбирать пасту с фтором, который укрепляет зубы и защищает от кариеса. Для чистки достаточно небольшого количества пасты размером с горошину. Не рекомендуется глотать зубную пасту.

Основная мысль: С развитием технологий зубная паста прошла долгий путь от примитивных средств до современных продуктов, обеспечивающих уход за зубами.
