just over a month ago I got a full restoration of B1 porcelain veneers and crowns in Costa Rica. Since then my teeth have turned more and more yellow as seen in photos. I don’t eat or drink anything routinely that would cause yellowing to normal teeth besides 1 coffee per day. I’ve reached out to the dentist and I’m waiting to hear back but wanted to get some opinions on how this can be happening. I am at a total loss and obviously very upset/concerned. Thanks for any insight!
