Hello doctor,

My teeth were not straight in the past, so I had braces to straighten them up (just finished my treatment last year). However, I still think there are multiple odd things in my face and upper/lower bites.

When I open my mouth wide, the right side of my face pops and my chin does not move straight down, instead it moves slightly to the left hope photo clears the situation. Second problem, I think my chin is recessed as shown in the side-profile photos.

Third problem is my upper and lower bites are not aligned below the center of the teeth and are not on top of each other. There is a clear gap between my upper and lower bite. It seems that my upper bite is forward but also my lower bite is recessed. Sometimes I feel my chin is too big for my face. It looks huge even when I only have a slight smile on my face.

I hope these issues make sense. I struggled to point out what is wrong with my face for years. Am I a good candidate for jaw surgery? What do I need to fix these issues?

I will answer your questions point wise as you mentioned.

The pop might be due to any joint dislocation present on the same side. And also considering your age, this is the time generally for the eruption of third molars what we generally call as wisdom teeth. When they come, they usually cause certain amount of deviation of one side of face and it usually subsides by itself after the teeth erupt. If not, we can go for treatment, no problem. Your chin is not recessed definitely. In fact the teeth and jaws are a little projected outward which is making you feel the chin is recessed (anyways this can be confirmed in a lateral cephalogram x-ray).

The alignment of the teeth, yes, the upper and lower centers are not in the midline. That has be corrected either with aligners, braces, or orthognathic jaw corrective surgery.

Yes, there is a gap between upper and lower teeth. The gap in between is called overjet and the depth is called overbite. This is due to presence of your upper jaw little forward and downward compared to the lower jaw. Here again, the mode of treatment for correction could be tried with braces and if not possible have to go for an upper jaw corrective surgery.

Yes, the chin looks a little too much. It can be corrected with a surgical procedure of chin reduction. Overall, I want to tell that all these issues definitely are present. But all these are not huge abnormalities, only minor issues. You definitely make a good candidate for a bimax surgery (both upper and lower jaw surgery) along with chin reduction.

My suggestion is as all these issues are not too severe, just try once more with braces usage and still, if not satisfied, you can go the surgery. Surgery definitely may give a good result, but still you have to get it done. Just think well, and then take a decision.
