Gold crown vs zirconia crown for molars? which is better?

Better?: Better is a subjective term. Better in what way? Each has pros and cons. If a any type of crown was universally better, it would be the only one used. Gold crowns cannot break and are softer and kinder to the opposing teeth. Zirconia crowns are strong but are more esthetic. This is a subject best discussed with your dentist who is most familiar with your specific situation.

Zirconia for molars: Zirconia crown is strong and durable as gold, but translucent with a better cosmetic result and less expensive.

Both : Both are great!! Gold wears more like enamel but esthetics are not there since its gold. Zirconia is esthetic & uber strong. Due to market pressures & cost most dentists will do zirconia over gold in today treatment. I'd go with zirconia but Both are great options for molars.

Speak with DDS: Speak with your dentist in regard to your individual parameters. Zirconia is more aesthetic than gold, but gold is the "gold standard".
