I lost my upper tooth on the right side (#5) 10-15 years ago. The gap between the teeth has almost closed. I noticed that my lips are assymetric now, since the teeth moved in a little and it caused a loss of volume in the right side of my face. Also the nasal-labial fold on the right side of my face is more prominent. What could be the option to fix it. Is it still possible to push over the teeth and put an implant or is it too late?
