Should I keep wearing them or just ditch them all together? (Photos)

Hello
The function of these is to retain the teeth in the position reached at the end of the orthodontic treatment.
The teeth have a natural tendency to move. Therefore, if the retainers are not used after orthodontics, they will eventually try to return to the position they had previously.
Regards.

It's pretty easy to move teeth. The complicated part of orthodontics is keeping them straight after treatment which is what retainers do. Typically teeth are moved to a position where they look good but are out of harmony with the muscles and bones. The best way to determine the right functional position is to stop wearing retainers. If the retainers either don't fit or are very tight, then you know that the forces moved the teeth. After four days probably not much shifting, but the only way to know if the shifting will continue is to not wear retainers. It is entirely possible that your teeth will go back to where they were before orthodontics, or close to it. Would repeating orthodontics be a problem? Would it be better to make some new retainers? These are questions that you have to ask yourself.
