No, they cannot withhold your crown if they have already prepared the tooth. They are obligated to see the procedure through to completion once it has been started, regardless of payment status. However, this does not mean you do not have to pay or can get away without paying. If you do not pay, they will go through a collections process, or possibly even sue you for non-payment of services rendered. It is generally easier just to arrange payment terms than to deal with collections, legal concerns, credit concerns, and possibly wrecking whatever relationship you have with your dentist.
Did you sign an agreement for the procedure? In my experience the impressions are made after the dentist has already built the core and installed a temporary crown. They usually order the permanent crown at that time, which they pay for. So the charge is justified. If this is not the case they should only be allowed to charge for the actual work done (office visit and taking the impression).
To get his crown. :)
For the extraction of his gold crown.
The cost of a crown will depend on what dentist you go to and what other things you have to go through to get the crown. On average, a crown will cost around $400.
I had a crown recemented by a dentist and it cost $96, but this seems really high to me.
Make an appointment with a competent dentist.
You can't whiten a crown. The shade of a crown is permanent and will not change with any whitening agents.
You could try asking the dentist about "bonding". I needed a crown, but my dentist chose not to crown it, but to build up the tooth. They matched it great and it's not that expensive.
When you visit a dentist for your crown or bridge, your dentist will "prepare" - remove your old crown, remove cavities of your tooth, etc. Then your dentist will take an impression of your "prepared" tooth and send it to a dental lab. The dental lab will then make your crown or bridge to replace your "prepared" tooth. Depending on the lab, your crown can be very good or not so good. When your dental crown crackles it is because of your crown is not prepared well. For more information about Dental crown visit www.identallab.com

You could do that, but I would not recommend it.First, you need to find out WHY the crown came off. If it is because of new dental decay, you want to have that taken care of by a dentist before you need a root canal.Second, super glue is not very effective as a dental cement. The crown will probably come off very soon again.Third, when a crown is placed, the dentist needs to check the bite. If it is off, even by a fraction of a millimeter, it can cause untold misery.Just see a dentist. If the crown can be re-cemented, the dentist can do it properly and quickly.
More than likely, the gums are either irritated by the temporary crown or they are inflamed due to inadequate oral hygiene. Ask your dentist for a prescription of Chlorhexedine Gluconate .12% (trade names are Peridex or Periogard). Rinse and brush with it daily until your permanent crown is placed.
