I think it depends on how long they were pierced. If they have only been pierced for a little while, there should be no problem.
If it's been a few years, and they just grew out to look funny, there will likely be a very slight scar... Like, a tiny little line that you can see if you look closely... Not a big deal.
Also... Depending on how long they were pierced, it may take quite a bit longer than 6 months to heal. Mine were pierced as a baby, and when I was old enough to do earrings myself I rarely bothered to put any in and would sometimes go a year or so without them closing. Heck, I went for 3 years without putting anything in, and they were still open. I got second holes when I was 13, and they are the same way. I only wore earrings in them regularly for about 2 years before I stopped wearing earrings much. I haven worn anything in them since the Mothers Day before last, and was still able to wear earrings in them for Halloween this year. My husband had his ears pierced when he was 10, stopped wearing his earring(s) when he was 16, and his are completely closed. I wouldn't even know get were ever pierced if his mom hadn't told me. Lol.
