The concerns about the changed bite, jaw position, facial asymmetry and neck pain need a proper clinical examination. Orthodontic treatment can change the bite and tooth position, but it is not possible to say from this history alone that it caused facial asymmetry or scoliosis. A tongue-tie may also contribute to certain oral or functional problems, but it needs to be assessed individually.

Hlo mam…..The symptoms described here suggest a complex interaction between dental alignment, temporomandibular joint (TMJ) function, tongue biomechanics, and posture. A definitive diagnosis requires an in-person clinical exam, bite analysis, and imaging (such as a TMJ MRI or OPG x-ray). Suspected Diagnoses & Underlying Reasons:- 1)Temporomandibular Joint Disorder (TMD) / Occlusal Dysfunctional Bite: An altered bite following clear aligner therapy can shift how the upper and lower teeth meet, causing backward (retruded) or asymmetrical (left-deviated) jaw position. This forces the jaw joint and surrounding chewing muscles out of alignment. 2)Cervicogenic Pain & Postural Compensation: The neck (cervical spine) and the jaw joint share extensive nerve connections and muscle networks. A misaligned jaw shifts head posture forward or laterally to compensate, triggering neck pain, muscle spasms, and functional spinal imbalance (often mimicking or exacerbating scoliosis-like symptoms). 3)Ankyloglossia (Tongue Tie): A restrictive lingual frenulum limits tongue mobility. The tongue plays a key role in resting against the roof of the mouth to support upper jaw posture; a tongue tie can exacerbate airway restriction, improper swallow patterns, and poor jaw placement.

I would recommend an evaluation by an orthodontist and an oral & maxillofacial surgeon, preferably with experience in jaw-joint (TMJ) and facial asymmetry cases. They can assess your bite, jaw position, facial symmetry, TMJ and tongue movement and decide whether an MAD is actually appropriate. If the cervical pain is significant or you have been diagnosed with scoliosis, please also consult an appropriate spine/orthopaedic specialist. Treatment should be planned after a proper examination rather than starting an MAD immediately.
