Hello there,I'm sorry to hear that you are unhappy with your results. You photos are a bit blurry, but from what I can see your smile looks great! Unfortunately, the time to change the shade of your crowns was before they were permanently cemented. If you are unhappy with the shade of your crowns, they would need to be replaced. This would involve your dentist cutting your current crowns off and having new ones made. I would suggest speaking with your dentist again about your concerns. Often times, the worst thing to do is to cut off the lines of communication with your dentist because you are upset. Good luck and I hope this helps. Follow me if you have more questions.Sarah Thompson, DMDSt. Louis, MO area (O'Fallon, IL)Real Self 100
