How Do Teeth Move?

Greetings, in this week’s article, I will try to talk about the nature of tooth movement without going into too much detail and confusing.

A large amount of tooth movement, which is now considered very normal for orthodontists, can cause a great surprise, especially in people who are not very interested in the subject. The treatment plan we foresee at the beginning of the treatments sometimes comes to the patients as movements that are hard to believe.

First of all, as basic information, the teeth stay in a bone cavity suitable for their roots in the jawbone. In other words, on the back of the gum, which we cannot see, a bone completely surrounds the teeth. There is a micron-level gap between this bone and tooth, and in this gap, a large number of fibers hold the tooth and bone together. In simple terms, you can think of a large number of thread-like tissue stretching between the tooth and bone.

The main factor in tooth movement is the flexibility of these fibers. We can roughly compare this to a shock absorber system. Teeth are exposed to lifelong forces and they have developed the ability to move to meet these forces. If such a mechanism did not occur, the teeth would have to wear out or break in the face of the incoming forces.

Orthodontic tooth movement is also practiced using this feature of the teeth. The forces given in orthodontics should be at an optimal level, that is, the teeth should be moved without blocking the capillary blood flow in the tissues between the bone and tooth. As uncontrolled forces will damage the teeth or bone, it will negatively affect both the treatment process and the health of these tissues.

After the forces are applied, the movement of the teeth continues actively for the first 2-3 days, the next process is kept long to wait for the formation of new bone. Unfortunately, the desire to speed up the treatment with very frequent appointments, which our patients sometimes impatiently want, is unfortunately not possible due to these structural conditions. Applying force to the tooth repeatedly will not cause movement and will damage the tissues.
