Still, be aware that drinking through straws does not prevent tooth decay.
Let's vanquish this urban legend right now. Straws do not make it safer to drink sugary beverages, according to dentist Mark Burhenne, DDS.

Dr. Burhenne suggests rinsing your mouth with water after finishing your can of Pepsi, and brushing your teeth 30 minutes later.
Still, straws are cool, oral hygiene is cool, and saving the planet is cool!
