The causes of tooth impaction.
While each case is unique, the most common cause of tooth impaction is that there is simply not a large enough open space for the tooth to make its way into a natural position through the gumline. It’s also common to observe teeth developing at a sharp angle that doesn’t guide the tooth towards a natural vacancy in the patient’s mouth. Both of these situations lead to the teeth residing in the bone rather than erupting into the mouth. The canine tooth is most commonly affected, but impaction can occur for any tooth.
In many cases, orthodontic treatment can create the space necessary for teeth to erupt naturally. Teeth naturally want to erupt, and creating appropriate space helps initiate this process in impacted teeth. For some stubborn teeth which don’t respond to the creation of space alone, an orthodontist can use a device called a “gold chain” which attaches to the tooth, and can be used to control the movement of the tooth and guide it into position.
