Use a Reusable Straw
It is a good idea to reduce the amount of juice/soda you consume in a day, but when you do have any liquid that contains sugar or acid, it is beneficial to use a reusable straw. The function of the straw is that it allows the fluid to bypass your teeth as you drink, thereby reducing the exposure to the sugars and acids contained in most drinks, and reducing cavity risk. Try to avoid plastic straws if possible.
