I have 2 upper carilitage ear piercings. I have had these two gosh four saken holes for about 10 years and I kid you not I have never not had a problem with them. Would I be better off to just let them grow over and have two new ones (only have the holes made by needle on the upper curve rim of outter skin around cartiliage). Wouldn't that be OK? All my other numerous lobe holes have always always done fine.

I guess I'm not understanding your question - if these piercings are not a problem why would you consider letting them "grow over" and then getting new piercings?

Not to mention, but the resulting scar tissue could present future problems if you were to let them heal and get re-pierced.

Some people's never grow over. I got mine pierced in the70's. I can go over 5 years without earrings and still wear earrings.
