Tooth mobility during orthodontic treatment?


Hello Doctor,
I started orthodontic treatment in March of this year using the so-called LH line and Damon braces.
When my second incisor on the right side erupted, it was inwardly positioned.
After the doctor helped to reposition that tooth, I noticed it became loose, and the looseness is quite noticeable.
For example, it wobbles when I brush my teeth.
I'm unsure if this is normal.
I have looked at various online resources and asked my orthodontist, and they all said it is normal.
However, it still feels like the wobbling is excessive, and I even have difficulty biting and cutting food.
I informed my doctor about the situation, and they separated the braces from the wire, suggesting that the tooth should rest for a while.
However, it has been a month since the separation, and due to the lack of force from the braces, the tooth has shifted back, but it still feels unstable.

I would like to ask the doctor, is this situation really normal? Thank you :)

More Info


Tooth mobility during orthodontic treatment is a common phenomenon and can often be considered a normal part of the process. When braces or other orthodontic appliances are applied, they exert forces on the teeth to move them into desired positions. This movement occurs because the periodontal ligament, which surrounds the tooth roots, adapts to the applied forces. As a result, some degree of tooth mobility can be expected, especially in the early stages of treatment or when significant movements are being made.

In your case, it sounds like you have experienced noticeable mobility in your teeth after the orthodontic adjustment. This can be concerning, especially if it affects your ability to chew or bite properly. However, it is important to understand that orthodontic treatment involves a delicate balance of forces, and the teeth may feel loose as they shift. The mobility you are experiencing is likely due to the adjustment of the periodontal ligaments and the bone surrounding the teeth as they adapt to the new positions.

Your orthodontist's decision to temporarily remove the appliance to allow your teeth to "rest" is a common approach when there is excessive mobility or discomfort. This rest period can help stabilize the teeth and allow the surrounding bone to remodel. However, it is also important to note that without the continuous gentle forces from the orthodontic appliance, the teeth may begin to drift back toward their original positions, which seems to be happening in your case.

It is crucial to maintain open communication with your orthodontist regarding your concerns. If the mobility persists or worsens, or if you experience pain or discomfort, it is essential to follow up with your orthodontist for further evaluation. They may need to adjust your treatment plan or provide additional support to ensure that your teeth are moving in a healthy and stable manner.

In terms of your ability to chew, if the mobility is significant enough to hinder your function, your orthodontist may consider temporary measures to improve your comfort while still allowing for necessary tooth movement. This could include adjustments to your diet or even temporary splints to stabilize the teeth during the treatment process.

In summary, while some degree of tooth mobility is normal during orthodontic treatment, it is essential to monitor the situation closely. If you feel that the mobility is excessive or affecting your quality of life, do not hesitate to reach out to your orthodontist for guidance. They are best equipped to assess your individual situation and make the necessary adjustments to your treatment plan. Remember, the goal of orthodontic treatment is not only to achieve a beautiful smile but also to ensure that your teeth and bite function properly throughout the process.
