Teething! (Me, not a kid)

So I've been growing this new tooth for a while, one of my 18 year old molars, apparently, taking their sweet ass time. It's not really bothering me at all, no pain or discomfort or anything, I thought it might've been something stuck in my gums when I first found it! Except that now (as of about an hour or two ago actually)I'm starting to be more aware of it. I can feel it there, or sometimes it feels like I'm chewing on my gums or something. Is that what teething rings are for, when babies go through this? Any tips or tricks for toothy sprouts? When did your last sets of teeth come in, (molars & wisdom teeth) and what was it like?
