I assume you mean in phase 1?
Each of the three phase 1 attack are telegraphed with a different visual or audio cue depending on the attack, at least 0.5 seconds before it could hit you, even if you run directly at it.

I have also previously made changes ensuring that the hitbox of the teeth is sized so that it can be dodged from any position in a hallway, even the middle of a a vertical one.

As soon as you hear the sound of the teeth appearing, hold either left or right, and you should be able to consistently dodge them.
