Relapse (movement) of teeth after previous teeth straightening is one of the most common reasons many of our patients seek Tooth Fairy Aligners. This is because many patients were not given retainers to keep their smile straight after braces treatment, or their retainers were lost/broken over time. Without adequate long term retention, your teeth will always want to move back into the position they were before. This is why retainers are useful.
We recommend for all our patients to wear their retainers ideally every night to prevent the relapsing of their teeth. The more you wear your retainers, the less movement will occur and the straighter your teeth stay! As you can imagine, by wearing retainers every night, it is very common for them to become worn or cracked in the space of one year.
