Extraction of crowned/bridged teeth?

[ouchie mowchie]

I am in declining health, and can no longer keep my upper dental work clean enough to be comfortable.

I have about 4 to 6 adult teeth in my upper mouth (I never had the seeds for most of my adult teeth) and I have one big piece of bridgework that covers the top of my mouth with of course the adult teeth as the anchors.

I have read that crowned teeth are extracted with tooth and all at one time. However this is not possible in my case.

To remove these teeth that have been filed down for the bridge work, would it be more complicated and expensive to remove them as a regular tooth? or not?

Thanks for your replies.
