You’ve finished your fixed braces, your teeth look great, your bite is perfect—and you might think you’re done. But now comes the crucial part of the entire orthodontic treatment, one that would be a big mistake to underestimate: retention. It is during this phase that removable braces, technically known as retention appliances, come into play. Why? And what can you expect? Find out in our article.
The reason is that teeth tend to shift back to their original position. Yes, even though you’ve spent the last X years with fixed braces in your mouth, your teeth can still shift back to the way they were before you got braces.
This is due to what is known as “tissue memory” and changes in the surrounding structures that occurred during orthodontic treatment. If you were to end treatment by removing your fixed braces without subsequent retention, you could lose all the progress you’ve made— within just a few months. And this is precisely where removable braces, or retention appliances, play a key role.
