What to do if you have swallowed the crown?
If a crown has been swallowed accidentally, the person concerned should wait until he or she has bowel movements and catch them. The crown poses no risk of injury to internal organs, as it is so small that it does not damage any structures. After the crown has been cleaned and disinfected, it can be firmly reattached without any problems.In most cases, no temporary restoration is required for the transitional period, since bowel movements can be expected after about 8 hours. During this time, chew on the other side to protect the residual limb.
What materials are used for the dental crown?
A crown can be made from different materials. Less popular today are gold crowns, which were considered the standard solution 20 years ago. Nevertheless, gold is very suitable as a crown material because of its good biocompatibility.
Biocompatibility describes to what extent the body tolerates the material. Furthermore, there are almost no gold allergies. The gold crown has been almost completely replaced by the development of non-precious metals.
The alloy chrome-cobalt-molybdenum has proven to be very suitable in terms of mechanics, durability and biocompatibility and can be produced at a much lower cost than gold. Furthermore, only a small percentage of allergies is known. Metal crowns and veneer crowns with a metal framework are generally used with phosphate cement.
This non-precious metal crown can also be veneered with ceramics, so that it appears tooth-colored. However, the ceramic crown made of zirconium oxide offers an even more aesthetically pleasing solution, since it does not have any metal-colored margins, as the non-precious metal crown does, and is therefore the best restoration, especially for the optically visible area. The ceramic restoration is somewhat more expensive than a non-precious metal restoration and must be used with special materials.
The tried and tested phosphate cement is not suitable for this purpose. This non-precious metal crown can also be veneered with ceramics, so that it appears tooth-colored.
