Doulbe crown

One of my front is teeth is currently a crown. It keeps coming loose and having to be recemented in or whatever it is they do to make a crown stay in. My dentist says that the post that is in there is partly damaged and my crown has no anchorage to stay in. I've only had it in but 6 months or so and it keeps coming loose. He said my only option is to get a double crown to have anchorage so that my crown can stay in permenantly. I am unfamiliar and unsure of this procedure. I have never heard of this before and is it truly effective? I would like to be more educated on the specific procedure and have some guarantees. I don't want my original tooth next to it to be ruined either. Is this my only other option as my dentist tells me? Can someone answer my questions? Please help! I did shedule the procedure but not for a little while yet. Need some professional experienced input!!!!

I am personally not a big fan of bridges if they can be avoided or in your case, a double crown joined together.  Did your dentist go over the option of a dental implant to replace the tooth?  It would require extracting the front tooth and replacing it with a titanium implant and then a crown on top.  That way, the other adjacent tooth is untouched.  The tooth with the loose crown sounds like it is non-restorable (non-salvageable).

   So how does a post become ruined in the first place? My dentist told me that the post is partially ruined underneath my crown. How does that happen? Reguarless if having insurance, I don't have the money to do an implant. My dentist did put my crown back in and believe it or not, it's the tightest and most stable it's EVER been. Should I just leave it alone for now and see what happens or will it eventually come loose again?

Its a chance you'll have to take if you want to leave it in. It may be fine or it may fracture or fall out again.  If it falls out, its not a big issue as long as it doesn't continue to break underneath.  I'm not sure where the break with the post is.  You'll have to ask him what he means by partially ruined.
