I have had root canal and it has cracked and left the root canal 'post' exposed. What are my next steps to resolve this? (Photo)

The tooth was treated 3 years ago, no crown was done. I have a small Amount of tooth to the front and whilst back remains ok. Does this mean a crown is possible? Or tooth bonding? I don't want to remove this tooth as cosmetically It's visble when I smile. I also have the same Tooth on the other side cracked and needing attention. The teeth are small, but again visible. I have been travelling and my dental care has gone out of the window in terms of routine checkups. help please
