I am a 45 year old female who has gray stained teeth due to taking Tetracycline in my early childhood. It is my understanding that there were no warnings that this could be a possible side effect. I have suffered from major depression most of my life because of this. I hate to smile, and don't like taking pictures. I am very self conscious. I wish I had the money to fix my teeth but have never had the financial means to do so. I have tried to research and find out if there have ever been any class action lawsuits regarding this and have found anything. I would appreciate any help or information you could give me.
