Why does my crown keep on chipping and cracking on one side?

Question

I replaced my 30 year old crown and since then i only had problems. It is going to be re-done for a 3rd time. What can i do about that?

If the same problem keeps occurring after three tries, it's probably time to alter the approach. There may be changes to your mouth that require a new fitting, a different crown material, or an alternative approach, which may require changes to the neighboring teeth. Talk to your dentist about your concerns in case there are problems with the lab, as well.

The breaking crown can be the result of the wrong choice of material the crown is made from for the forces.  Ceramic rrowns are only strong after excellent bonding procedures.Bite issues can also be involved in your crown breaking.Occasionally in all ceramic crowns sharp edges on prepared tooth can lead to breakage.It is also possible that there is a lab error in producing the crown.There are high end labs that are very expensive and very cheap labs.  Both can be good but in general you get what you pay for.  Doctors in PPOs and HMOs usually are forced to use cheaper labs due to small financial margins for the doctor.
