Though the most common reason for a loose tooth in adults is periodontal disease (gum disease); trauma, bite injury or tumor can also cause teeth mobility. Certain amount of tooth mobility is always present and it is natural, as the teeth are not fixed tight in their sockets.
However, because the small roots should dissolve first, loose teeth should not be yanked out abruptly. Otherwise, it is possible for the remaining root to break and become infected. What to Expect explains that baby teeth typically start falling out when a child is 6 years old. The Parents website states that baby teeth can fall out as early as 4 years old or as late as 8 years old. Teeth emerge and drop out following the same pattern.
