Help please stuck in feasters lair

[WOOHOOICECREAM!!!]

hey guys i got the quest to kill the boss in feasters lair. I made my way through nerveroot and im at the checkpoint called sunken bones in feasters lair. Only problem is my path is blocked by a obstacle that looks like teeth and whenever i try to go through it it just chomps me. I tried going up but that leads nowhere and this seems like the primary path. I am totally stumped. Any help would be greatly appreciated cause i love this game and just want to play it more.

jump over without touching teeth

Are they long and pointy teeth, like from a guinea pig? You can jump through those without touching them or dash which I prefer. If they are the bigger set of teeth, wider and thicker, dashing through them is better, because they will react faster.
Edit: Maybe it´s an area you need to access from the other side and can´t yet get there because you can´t yet use an ability. Overall if you encounter something that stumps you, come back to it later.
