That is not going to fix itself. I had the same problem twice with my favourite stimmie, but she couldn't be fixed a second time. These both occured when eating and she put the prey item on the ground and was "above" it pushing down on it, if that makes sense. So the prey is facing downwards and the snake is putting pressure on it the jaw gets pushed across and the teeth trap it under the skin. Hers was a bit further across though.
They will have to sedate it and then cut it open, move the skin off the teeth and stitch it back up. I think it only cost about $300 including the after hours vet bill.
