• It cannot fix an overbite due to the fact that the mouthpiece is designed as one shape to fit the mouth rather than multiple parts that can fit a mouth with an overbite.
    • This limitation makes the device only useful to those that wish to straighten their teeth due to malocclusion or cosmetic reasons, but unfortunately won’t be able to help those with a misaligned jaw.

    • This puts the bulk of the responsibility on the patient themselves if the device is not used correctly or as often as it should, it may not produce the desired results.
