I used to have an underbite But had it fixed at the dentist. I've always had a protruded chin, especially when I smile. My chin over the years has seemed to protrude even more and throughout the past year my chin has seemed to shift towards my left side. Is it even possible for a chin to shift towards one side while you age/get older? If so, will it get worse as time goes by and what can I do to fix it? Are there any non surgical procedures?The center of both my upper and lower teeth align.
