PLEASE HELP!

My 9 month old is in the midst of cutting another tooth. The first 2 didn't give us much problem, but little sucker has brought along sleep regression. She sleeps maybe a 3-4 span, then wakes up and just screams for hours on end. In these hours, she'll sleep for maybe 1-2 minutes and wake doing it again. It's miserable for her and us (mama and daddy). You can tell she's exhausted, as are we. Please, someone, give me some tips on what I can do to help this!
