NEED ADVICE ON JAW ASYMMETRY, WISDOM TEETH AND PREMOLAR EXTRACTION

Hi everyone! I’ve recently started diving into the world of orthodontics and jaw health after realizing I’ve been a chronic mouth breather for years. It’s been an eye-opening journey, and I’m now uncovering issues I never knew I had. I’d really appreciate your insights and advice as I try to navigate this confusing situation.

My Situation:
For a long time, I thought my bite was fine, and even a dentist confirmed it. However, upon closer inspection, I noticed a clear asymmetry:
- The right side of my bite seems okay.
- The left side has a noticeable gap between the upper and lower premolars (I think they’re premolars, but I’m not entirely sure).

I recently took an X-ray, and it revealed:
- My left wisdom tooth is impacted (lying horizontally and not erupted).
- The left side of my jaw appears underdeveloped, with the ramus almost nonexistent.
- The right side, where the wisdom tooth is erupting, looks normal.

Additionally, when I open my mouth wide, my face deviates to the left side (the underdeveloped side).

I also have a scalloped tongue, which I’m concerned about because I have a narrow palate. I’ve read that this could be related to tongue posture or jaw issues, but I’m not entirely sure.

My Concerns:
I initially wanted to fix my teeth alignment, but when I consulted a dentist, they recommended extracting 4 premolars to create space, as my wisdom tooth is stuck due to crowding. However, I’ve read that premolar extractions can narrow the jaw further, and I already have a narrow, long face. I’m worried this could make things worse.

My Questions:
1. Could my asymmetric jaw development be linked to my mouth breathing or the impacted wisdom tooth?
2. Is premolar extraction the best option, or are there alternatives to address crowding without compromising my jaw structure?
3. How can I improve the underdeveloped side of my jaw? Are there specific treatments or exercises that could help?
4. Could my scalloped tongue and narrow palate be contributing to these issues? What can I do to address them?
5. Should I consult an orthodontist or maxillofacial surgeon for a second opinion?

I’ve attached photos with more specific questions for clarity.

Thank you so much for taking the time to read this! I’m feeling a bit overwhelmed but hopeful to find solutions. Any advice, personal experiences, or recommendations would mean the world to me. Grateful for this community and your expertise!
