Tooth number 2, one cusp and the root are lost, suggestions?

[rick422]

Hi! My molar (Tooth number 2) got damaged, one cusp and its root came out. I went to a dentist, he told me that he will place a PFM cap. This has absolutely confused me, because I believe that crowns are placed only if ENTIRE site (where tooth was lost) has some tooth above gumline. But in my case, entire cusp and root are lost, so how will he place the crown? one cusp of the crown will have nothing to support it from below. I suspect the crown will fall out.

Am I right? Kindly advise.

If root gone, then you must've had some partial extraction, correct? Would also mean your nerve (pulp) is exposed, and would need RCT. This doesn't sound likely to me. Provide Xray pls.
