Surgeries and Procedures: Casts and Splints. Broken bones, or fractures, are a common hazard of childhood. And although breaking a bone takes only a split-second fall off the jungle gym or a quick collision on the soccer field, the healing process takes a bit longer.
In some cases, you may even grind your teeth back and forth, further stretching the ligaments. This can cause your teeth to feel loose in the mornings. Another common cause of loose teeth is gum disease. When plaque and other deposits begin to develop beneath the gum line, an infection can occur. When left untreated, this infection can destroy gum tissue and damage the periodontal ligaments holding your tooth in place.
As youngsters grow, their permanent teeth usually dissolve the roots of their baby teeth. Once the root is nearly gone, a baby tooth gets loose. Eventually it will fall out, and many children accelerate the process by wiggling it and pulling on it. Then the permanent tooth can grow in the empty spot. With shark teeth, the root doesn't dissolve quickly enough. The baby tooth stays in place, and the permanent tooth works its way up in the space behind it.
