Mine started coming in a few years ago and probably took over a year easily for them to finally stop coming up. They made the gums quite sore for that year, but now they are fine, I think. I haven't been to the dentist in a lonnnnnng time for anything except for chipped and broken teeth. Mine all feel pretty straight when I touch them with my tongue, and did not affect my other teeth... bu I really should make an appointment since it's been much longer than I am willing to admit that I have been in for a cleaning.....
