Today, toothpaste tubes are filled using machines. All the empty tubes are lined up on a conveyer belt with their caps downwards and the unsealed end pointing up. A big container filled with toothpaste is fixed above the conveyor belt.
From a nozzle at the bottom of the container, the toothpaste is let into each of these tubes as they move along the conveyor belt. But the paste is not filled all the way to the brim. About half an inch is left so that it can be sealed. Now the tube is ready to be squeezed!
Many people in India use datun, the twig of a neem or babool tree, instead of a factory-made brush. Datun keeps teeth and gums healthy. But do you know which the best brush in the world is? Your fingers, say dentists! Great for the teeth and gums.
Have you tried tooth powder? What are the different smells that you can detect in it? Herbs and spices that are good for teeth include mint, clove, cinnamon, black pepper and tulsi. Eating fibrous fruits and vegetables, like apples and carrots, is good for cleaning teeth.
