3 double jaw surgeries to fix a cant and asymmetry, but my smile has been made worse. It shows very little teeth (Photo)

I'm sorry to hear about your distress. It's understandable to feel overwhelmed after multiple surgeries that haven't fully addressed your concerns. A fourth surgery could potentially help, but it would depend on several factors, including your overall health, the condition of your jaw, and whether the desired outcome is achievable.
Here are some steps to consider:
Get a Second (or Third) Opinion: Consulting with other experienced oral and maxillofacial surgeons who specialize in complex cases could provide new perspectives on your situation. They might be able to offer different techniques or approaches that could be more effective.
3D Imaging and Surgical Planning: Advanced 3D imaging and virtual surgical planning can provide more precise outcomes. These tools allow surgeons to simulate the surgery beforehand, which may increase the chances of getting the desired result.
Consider Non-Surgical Options: If further surgery carries significant risks, you might want to explore non-surgical treatments, such as orthodontic adjustments, dental veneers, or gum contouring, to improve aesthetics.
Emotional Support: It’s understandable to feel distressed after such a challenging journey. Seeking support from a counselor or a support group for people who’ve undergone similar surgeries might help you cope with the emotional toll.
Ultimately, a detailed consultation with your healthcare providers will be critical in making the decision about whether another surgery is advisable.
