Introduction

It's time to show off those pearly whites and get ready to celebrate National Smile Day on May 31! National Smile Day was created in 1999 in response to the growing number of people that felt disconnected from one another. The idea behind this day is to spread happiness and positivity by encouraging everyone to smile, no matter what their circumstances may be. On this day, it doesn't matter if you're rich or poor, young or old – all that matters is that you put a smile on someone else's face. So let's make sure we take some time out of our busy lives and show some random acts of kindness and smiles to all those around us!
