Invisalign before and after jaw alignment
Clear aligners can move teeth and influence the bite, but they cannot reshape an adult jaw or correct every skeletal alignment problem.
The short answer
Clear aligners can straighten teeth and improve how the upper and lower teeth meet, but they cannot reshape an adult jaw or correct every skeletal jaw discrepancy. Before-and-after changes therefore depend on whether the problem is tooth position, the bite, or the size and position of the jaw bones.

How do teeth and jaw bones differ in aligner treatment?
An aligner is a thin thermoplastic tray that applies planned forces to individual teeth through attachments and staged trays. Jaw alignment may mean dental midlines and bite contacts, or a skeletal relationship between the maxilla and mandible, which requires different assessment and sometimes jaw surgery.
How is jaw alignment assessed before choosing aligners?
An orthodontist examines facial balance, jaw movement, photographs, scans, and bite records, then may use digital tooth movement planning. Treatment can include aligners, elastics, fixed appliances, growth modification in a child, or referral for orthognathic surgery when tooth movement alone cannot correct the bone relationship.
When should a jaw or bite concern see an orthodontist?
Arrange an assessment if the bite causes chewing difficulty, jaw pain, tooth wear, speech changes, or an inability to close the lips comfortably. Seek prompt care for a new locked jaw, major swelling, facial injury, or rapidly changing bite.
What should you ask about aligners and jaw alignment?
Ask whether your concern is dental or skeletal, what the planned tooth movements are, and which changes are realistic without surgery. Ask how attachments, elastics, retainers, bite refinement, and monitoring will affect the final result.
Frequently asked questions
Can aligners fix an overbite?
They can improve many tooth-position and bite relationships, but the achievable correction depends on the cause, growth status, and severity.
Will my face change after aligner treatment?
Tooth and lip position may alter facial appearance slightly, but aligners are not a substitute for treatment of a major skeletal discrepancy.
