If any friends have any experience and comments or recommendation.
I recently visited a neighbor American dentist. The quote for root canal on one right side tooth is $1225. Crown $1095. And the dentist reviewed my left side tooth which was done root canal in China. The dentist needs to redo it for crown. The rationale is that the fill is too close to nerves, which may not be dead. I feel not perfect, but ok to live with it.
