New to baby wearing, anyone know any carriers or slings that won't leave marks

You can get strap covers that they can chew on instead of the actual carrier. They often are a soft, thick fabric, with Velcro that wraps around the area of the carrier or wrap that many babies chew on, and come in lots of different patterns out there. Maybe that would also provide a softer surface for her face when she leans against the edge, although I don't know for sure.

I know Lenny Lamb sells things like that, and they aren't the only brand that does. Some carriers come with them, too.

I have a baby Björn mini in the cotton fabric and it’s very soft. My LO chews on the side as well and I haven’t seen any marks as far as I’m aware. They are also machine washable

The marks are like sock marks. If they fade after a while and baby doesn't seem too bothered, it should be fine. As Emmons says Lenny Lamb does suck pads. Or Annie's accessories makes lovely suckpads and other carrier covers for cold times too
