Hi, I had a full set of veneers placed about 6 months ago and I’ve noticed the biting surface of one of the central incisors feels chalky when I brush my finger over it. The other incisor and the other veneered teeth have a smooth glossy feeling. Does this mean that the lab didn’t glaze this veneer properly? How could this be fixed? I don’t recall if the dentist smoothed the biting edge upon installation but could this have caused the chalky texture?
