###Human: Which crown is better for endodontically treated molar - zirconia or emax? ###Assistant: Hi. Zirconium crown will be a better choice because you are young. If the tooth is properly adjusted, that is, if the crown placement is done properly, there will not be abrasive effects. Yes, it costs a little more than ceramic or porcelain-fused metal crown, but they will chip off with time. For more information consult a dentist online -->
