Your earlobes will not "heal" by themselves. The "tracts" or "holes" are vertically or longitudinally stretched as is very common with time, age, and wearing heavy earrings over time. The best solution in my opinion is to repair this and allow it to fully heal. This is a simple office procedure I do commonly. We typically re-pierce the earlobes 6 weeks after healing. I hope this helps!
Your large piercings may need to have the skin along the inside of the holes removed, and have sutures placed to bring the skin together. Sutures are removed around one week postoperative, and ears may be re-pierced in an area close to, but not on the scars. There is no non-surgical method for repair that we are aware of.
