Hachibi actually lost that tooth earlier in the battle against the Juubi. (Chapter 615)

At that time, Bee launched himself at the Juubi in his Hachibi form, and aimed a Bijuu Dama (Tailed Beast Bomb) at the Juubi's mouth. He exploded the Bijuu Dama inside the Juubi's mouth causing it great pain, but the Hachibi also took some damage, losing a tooth and yet another horn.
