Your tiger tooth aloe is stretching for several reasons: First, it needs more light. Second, it's getting too much water. Third, the soil needs better drainage. Fourth, it lacks nutrients. If you have these issues, you're not alone. Many plant owners have these problems, and they can be fixed! My advice? Repot it with cactus or succulent soil, fertilize it regularly with a liquid fertilizer, and watch it thrive quickly!
