Can a zirconium crown de drilled in the future for a root canal without damage?

Question

A piece broke off my topback molar. The x-ray doesn't show that I need a root canal but when the doctor did a bite test it hurts when I bite on something with a lot of pressure. He suggested a zirconium crown and said that it’s a possibility that I need a root canal later. He would drill a whole on it if I need it. Today's technology why can I get a better scan to confirm that root canal is needed or not? Also how can a Zirconium crown be drilled without any damage! I'm sceptica

There is surely a risk of damaging the Zirconium crown, but it is still possible to make the root canal treatment without any problem. It can only be decided and seen during the treatment process.

Thanks for the question.
It is not really possible to drill the zirconium crown without damage. Even if its aesthetic quality persists, the endurance will be very poor which results in a decrease in life expectancy of the crown. Therefore, if the pain persists root canal or indirect pulp capping can be applied; nevertheless, without physical examination and x-ray neither of them can be included in treatment plan.
All indications given are estimated and can be changed after the physical examination and x-ray.
