I am worried about the development of my lower jaw.Please help.

Hello doctor,

• I have a question about the normal development of facial structure of a male going through puberty.

• I am 17 years old, my height is 5'7" and I weigh 119 pounds. My diet is normal.

• I am very frail in stature but, that is not what I am worried about.

• I am worried about the development of my lower jaw.

• It seems extremely small for my face and to me it seems like a problem.

• That is not only a very unattractive feature, but also seems unhealthy in a way.

• I had braces for a year and a half but, that did nothing.

• I am not sure if it is genetic or if it is a disease but, my jaw seems to be to small for the structure of my face.

• I am in deep need of help to further understand why is this happening as I grow and I was wondering if I could do anything to fix it without surgery.

• I feel like it is a problem and it is a flaw and I have been wondering this question for quite a while.

The sources I read lack information and contain uncertainties. Please explain.
