Operation Smile is getting underway this week.
Operation Smile helps children who suffer from cleft lip and cleft palate through surgery, speech therapy, and dental and orthodontic care.
This month, you'll find Lay's potato chip bags that feature infectious smiles. When you buy one, Lay's makes a donation to Operation Smile.
You can even make your own smile bag by going to Lays.com by the end of the month and uploading a picture of yourself or a friend smiling.
