A Lost Tooth -Replace it
with a Dental Crown
• A local anaesthetic will be administered and the dental surgeon will
concern himself with filling and sealing the tooth roots after first removing
the nerves. Impressions are then taken so that the dental mechanics at
the laboratory can make a plaster cast of your entire gums and teeth. A
porcelain crown is an exact replacement for a tooth. The plaster molds of
your complete jaw and teeth will be sent back to the dental surgeon with a
strip of wax attached. This is in order for you to bite and leave and
impression on it. This is a very important procedure as you must have a
correct bite.
• Once this is done it is sent back to the dental laboratory together with an
exact colour swatch of your teeth. This is in order to ensure the crown
colour matches the rest of the teeth. After a week the plaster molds will be
received back by the dental surgeon. In the place where the broken or
decayed tooth was located, will be a white metal/porcelain crown, usually a
composite material of platinum and porcelain. This is not the final
product as it has to be baked (fired in an oven) at a temperature of around
950oC. There may be a post in the crown which will fit down into the
socket the dental surgeon had provided for added strength. At the first
fitting of this crown it will not be cemented in place but fitted to make
sure the bite is correct. It is possible that it will need a little grinding so
that it fits in with the rest of the teeth. After this is accomplished it is
returned once again to the dental laboratory for baking in the oven.
Finally, the finished product is returned to the dental surgeon and is
securely cemented in place with an extremely strong two-part adhesive
and the job is done. You will not be able to tell the difference in this crown
from your own tooth, a complete replacement.
