I am trying to create a mouth clenching it's teeth together as part of a trophy I am designing. It's supposed to be an angry basketball.

To create the mouth, I imported a shape and made it a hole to fit on my basketball. To create the teeth I just duplicated little squares and placed them next to eachother in the empty space which will be the mouth. I can't align the teeth to sit evenly as the shape of the mouth slopes down on either side and the teeth at the corners have to sit further back than the ones in the center or the teeth stick out. How do I align or design the teeth to sit stacked on top of and next to each other as forward as I can without the teeth spilling out of the sides?
