What is the Warranty on a Molar Dental Crown Which Cracked and is Less Than 1 Year Old?

I would encourage you to call your dentist and tell him what happened.  Most dentists want to make you happy and if it was only temporarily cemented, there must have been a future plan about permanent cementation.  Most dentists will do work over at no charge or reduced charges if patients are not having success with their work.

Best of Luck,

Most dental practices do not warranty their work legally, but they want to make their patients happy and satisfied with their teeth and smile. The crown had temporary cement and you have had it only for nine months. Unless you grind or clench your teeth, or did something that would your hurt your teeth, as taking of bottle caps, I would think your dentist would replace it free of charge. Go back to your dentist and see why it happened and what he will do that would remedy the problem.  Some dental offices do warranty their work and will stand by what they say. Go see him and discuss the problem. I am assured you will be able to work this out!  I would replace it free of charge!

Each and every office differs in how they handle work that has failed.  For a crown that is less than one year old in my office I would replace it at no charge.  I would discuss your concerns with your dentist and see what they have to say.  Best of luck
