The mouth is the window to the soul. It’s prime real estate in your body, and every biological system that you have puts up a flagship store there — from the digestive system, nervous system and even the immune system. On this week’s show, we examine the dentist’s role in the opioid crisis, talk about a decision many parents face when their child is tongue-tied, and we look back at the long history of mouth decor.

Plus, we take a trip to the aquarium to look into one of the most feared and revered mouths on our planet. 

Open wide and say, “ahhhhhh!”
