[|Human|] I have had cubic zirconia crowns put on a couple molars over the past 3 years or so.  I have had nothing but trouble...cracking, breaking, chipping of these...at least 3 times!! this morning, the crown i had fitted one year ago just cracked/broke. So I am going in to see him this afternoon.  I was told its under warranty.  I have a new dentist now because my insurance recently changed.  Should i be looking into getting a different kind of material?The dentist said he recommended the expensive crowns because i have an immune system health issue.  Is he just trying to make more $$?
[|AI|]  Hi, Thanks for asking the query, Chipping and breaking of the zirconia crown occurs when your biting forces are high. I would suggest you to visit the Prosthodontist and look for a full ceramic or metal fused to ceramic crown, discuss with your Dentist about the treatment options. Zirconia crowns do not have any relation with your immune system, so you can definitely think of different treatment options. Maintain a good oral hygiene use antiseptic mouthwash rinses twice daily. Hope this helps out. Regards.
