What can I do about my porcelain crowns being uneven? (Photo)

Your porcelain crowns on top teeth are uneven, and in dentistry term we say the teeth or crowns are canted !Unfortunately your good dentist can not just shave or adjust the crowns to correct your smile, he must now remove all your crowns and redo them, and take face-bow recordings, and pay much more attention to details of your lips, eyes, nose , ears and your bite and occlusion.He might also need to alter the preparation, but it can all be fixed to your satisfaction. 

The veneers are certainly canted.  They will likely need to be remade.  There are steps that your dentist will take to be sure that lab is able to correct this in your new set.  Good luck.

Thanks for posting a photo. It really helps to evaluate your situation. Yes you are definately uneven. This is called a cant. The only thing you can do is return to the dentist and have the crowns remade. It should not be difficult to correct with better attention to detail by both your dentist and the lab.

My recomendation is to re do the complete proceedure , one of the most important things is before you let them place in , there are methods to check the last layout.you can see the way they will look before they glue them .one they are glued there is not much to do.if your doctor is a cosmetic doctor he will be the first to tell you , they need to be re done .but yes you have a solution!
