What does “Orthodontic relapse” mean?
Orthodontic relapse is a change in tooth alignment or the bite back toward its original position after treatment.
Change in movement in the original direction
As the tissues surrounding teeth adapt to their new position, they tend to revert. Changes in arrangement due to growth and age that occur over time may also occur, so all changes cannot be explained by only one cause.
Check retainer and current arrangement
The position may change if you stop wearing the retainer, if the device is deformed or damaged, or if the fixed adhesive falls off. We check whether the device fits well, the changed position of the teeth, and the condition of the gums. Do not force the old device into place.
How to manage again
For small, stable changes, retainer adjustment or replacement may be considered. If tooth movement is needed, limited or additional orthodontic treatment may be considered. The extent depends on the current bite and desired changes, and a retention plan is still necessary after retreatment.
Frequently Asked Questions
Can recurrence occur even after using the retainer for a long time?
Teeth may change in the long term, and the condition and wearing of the appliance also affect it. The need for maintenance does not disappear just because it has been used for a long time.
Does relapse mean I need to start full orthodontic treatment again?
Not necessarily. The extent of the changes, the bite, and the retainer’s condition are assessed to determine whether retention can be improved or additional orthodontic treatment is needed.
