Get to know the major disadvantages of non-certified zirconia crowns.

Non-branded zirconia crowns are also called Chinese dental crowns or non-medically certified dental crowns. They are basic dental crowns that are not certified by any agency or company. Even the manufacturing company does not claim that it does not have any side effects. They are comparatively cheaper but come without a warranty. On the other hand, the crowns made by certified or branded companies also called premium zirconia crowns are the ones which are free from all types of problems in your mouth and do not give any side effects or allergies. Certified companies manufacturing these crowns give a warranty on their product which may be 10 years to 15 years. These crowns can go on for a lifetime also.
