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.
Also at around age six, children start to lose their primary teeth. The roots slowly get weak, and the tooth falls out. Children lose primary teeth until they are about 12 years old. It's okay for children to wiggle their primary teeth if they are loose. But it's not okay to use force to pull out a tooth that's not ready to come out. When a tooth comes out at the right time, there will be very little bleeding.
