What could be a potential consequence of not replacing a damaged tooth in time?

Not replacing a damaged tooth in a road grader in a timely manner can lead to uneven grading outcomes. The teeth on a grader are essential for cutting, shaping, and leveling the surface of the road. When one or more teeth are damaged, the cutting edge is compromised, resulting in inconsistent material removal. This can produce uneven surfaces, which not only affects the quality of the road but can also lead to safety hazards for vehicles and increased wear on the grader itself.

The other options do not directly relate to the immediate consequences of neglecting to replace a damaged tooth. Options involving fuel efficiency, grading performance improvements, and tire condition restoration do not address the specific outcome of compromising the grading process due to damaged equipment. The focus should remain on how the functionality of the grader is affected by the condition of its components, particularly how a missing or damaged tooth results in subpar performance in the grading task.
