Either my jaw, teeth, or lip is crooked. How can I fix it? (Photo)

Asymmetry of the face is a normal part of how our faces are supposed to look. Creating more symmetry to the face can help bring balance and harmony of the face.  A detailed in person analysis can help determine the cause of asymmetry including:
Underlying skeletal imbalanceSoft tissue asymmetryAsymmetry in dynamic movements of the face and expressionsNot all treatment options involve surgery with some less invasive options involving facial fillers and neuromodulators helpful in many cases.

Thanks for the question and thanks for including the photo – another one with a closed mouth could also be helpful for us. We always recommend that you make a consultation with a board certified dermatologist or plastic surgeon to have a thorough examination and to learn all of the potential therapies that would exist to even things out. We are all asymmetric in some shape or fashion. When fillers and neurotoxins are used correctly, it is possible to minimize these asymmetries. Find the proper physician and see what is best for you.

Your current picture is not helpful in answering your question. Non-smiling closed mouth pictures are needed from different angles to make a more thorough facial/jawline assessment.
