Why Do Teeth Loosen During Orthodontic Treatment?

"I heard that orthodontics can loosen teeth?", "Are there any side effects of orthodontics?", "Can orthodontics be done in my case?" It is human nature to love beauty. I believe many people are very envious of celebrities with neat and white teeth on the screen. And more or less have moved the idea of orthodontic treatment, but the understanding of orthodontic treatment is almost zero. Don't worry, today IMD is here to talk to you about a topic that everyone cares about orthodontics - whether orthodontic treatment will loosen your teeth.


1. What is the reason for loose teeth during orthodontic treatment?


First of all, we have to explain a concept, that is, "tooth loosening" is also classified, and they can be divided into pathological movement and physiological movement.


① Pathological movement: generally defined as tooth displacement that occurs when the balance between factors that maintain physiological tooth position is disturbed by periodontal disease. (In short, disease-induced loosening)

② Physiological Movement: it usually refers to the force acting on the teeth that dislodges the teeth. (In short, the safety loosening due to force)


Our normal teeth also have a certain degree of looseness. For example, when we use the index finger to pull the teeth forcefully, we will obviously feel a tingling sensation in the gums. At this time, the teeth are already moving slightly. The loosening is so slight that it is almost imperceptible.


Our teeth are not nailed in place like "nails", but "suspended" in the alveolar bone. Once subjected to force, the extremely elastic and tough periodontal ligament will allow our teeth to have a certain degree of loosening to avoid damage.


Note: if there is obvious loosening of the teeth, you need to be alert to whether it is pathological loosening, and you should go to the hospital for professional treatment as soon as possible.


2. What is orthodontic treatment?


As mentioned above, orthodontic treatment uses external force to make the uneven teeth move safely and slowly according to the treatment plan and align them neatly. It belongs to physiological movement.


This kind of loosening will not cause pathological damage to the tooth itself and its supporting tissues ( gums, periodontal ligament, etc.), which is a normal situation. As for how it is fixed after being displaced, it all depends on the biological response of alveolar bone, periodontal ligament and other tissues.


First of all, the orthodontic treatment of teeth is a process of movement and reconstruction, which involves four important roles of osteoclasts, osteoblasts, alveolar bone & appliances.


We can think of orthodontic treatment as a ploughing process. The alveolar bone is the soil, and the teeth are the crops. The appliance is like an ox that ploughs the field, guiding and applying force. Osteoclasts are like plows in the tilled field, constantly renewing the soil in front of them so that the teeth can move smoothly. Osteoblasts are like people who wield a leather whip, constantly waving the whip to move the plow forward and push the teeth forward.


When our tooth is re-transplanted to a new position, its roots will be extended and deeply plucked in the new soil to form a fixed structure. At this time, our teeth are officially orthodontized.


Doing orthodontic treatment must not blindly map fast! Once the correction speed is too fast, the speed of bone resorption is faster than the speed of new bone formation, and it becomes pathological loosening. Therefore, it is the most important thing to choose an experienced orthodontist before doing orthodontic treatment!


As for the loose teeth caused by the correction of moving teeth that everyone is worried about, there is no problem at all! After our teeth are moved into the correct position, the alveolar bone around the teeth is remodeled and will be as strong as before!


Some orthodontic patients may experience mild tooth loosening, soreness, discomfort, and inability to chew during orthodontic treatment, which are normal reactions during orthodontic treatment. In fact, after orthodontic treatment, since the teeth are aligned, it is conducive to oral cleaning, which can assist in the treatment of periodontal disease. In a sense, orthodontic treatment can also prevent the teeth from loosening after aging!
