Are Tae Yeon's top row of teeth porcelain veneers? I always thought they were veneers based on the difference between her smile in her pre-debut photos and her current photos, but my friend doesn't think so. He thinks they just filed them to look that way since his cousin's teeth were filed to look nice. He also thinks Yunho's (from DBSK) new (well, not so new now) smile are not veneers, but I'm pretty sure they are veneers since his crooked teeth disappeared overnight. Just wondering...
