I've never used that much. I just assumed it was to look nice since a pea sized about would look silly in a picture. I think it I used that much my mouth would be so full of foam it would be uncomfortable

I swear it's also why they made that newer garbage cap design that slowly leaks toothpaste and gums up unless you carefully clean the end and fully close it every time. I know y'all know what I am talking about!

Fools up your game. Tom's toothpaste is so absolutely classy. My gums never felt this good. Better ask jeeves.good ass toothpaste.

in fairness the directions on the back of the tube still state you should use a pea sized amount. i feel like that's not all that helpful though, peas come in lots of different sizes.
