crowns used ?
A crown may be used to repair a damaged or decayed tooth, to better the cosmetic appearance of a broken or decayed tooth and also to strengthen a tooth weakened by decay, breakage or injury.
a filling instead of a crown ?
problem is that this would be similar to building a whole house
wall using cement and no bricks or steel strengthening rods.
with teeth and just substitute the weight of the roof by the sheer
pressure exerted when one bites onto something.
Also - and this is the main reason - no amount of manual filling or sculpting by the dentists can get the freeform filling material into such a perfect mouth fitting shape as the lab made crown made from a cast form taken of both the lower and upper jaw.
So where there is too much tooth missing, it is easier, and much more practical to get a crown made than to plaster up the hole with filling material.
Last but not least
- a dental crown is made in the lab from the cast and is modeled, baked,
filed and heated outside of your mouth - which means much less fiddling
around on and around the broken or decayed tooth thus exposing the already
weakened area to even more pounding.
dental crowns prepared for, made and then fitted :
When all this is done a cast will be taken to get the exact form of the teeth and to allow the laboratory technicians to make an exact replica - or a precise copy of the crown which when fitted will fit with the existing teeth and the mouth bite.
Mostly, a temporary crown or a several teeth spanning bridge (a tooth out of the tube or fast made by the lab ) is fitted for the 3 or 4 days whilst one waits for the crown to be made by the lab.
Once the crown fits perfectly, and the patient and dentist are both happy that the jaw can close normally and the tooth has a good bite grip, with no part of the new crown too high or grating improperly on the teeth below or above it - it is then cemented permanently into place.

can a dental crown last ?
This depends on how big the crown was as compared to the size of what remained of the original tooth, where it is in the mouth, (hence how much pressure will be exerted - molars exert much more pressure than incisors) what material it was made from and many other factors concerning the care one has for their teeth etc. etc.
