As illustrated above, teeth with larger fillings are more likely to fracture than those with smaller fillings. The size of the filling depends on the size of the cavity previously present - the larger the cavity, the larger the filling.
Fractures are unpredictable. When teeth fracture, they usually break in such a way that the tooth cannot be rebuilt, resulting in its loss.
To avoid having such fractures, the dentist will often recommend a crown-restoration when he notices the filling to be too large. Sometimes, a crown can still be placed on a tooth - even though a fracture has already occurred.
Before preparing the tooth for a crown, the dentist would first re-build the missing tooth components.
The dentist would then prepare & shape the built-up tooth for a crown. An impression (duplicate model) is then taken of the prepared & shaped tooth. The impression is sent to the lab for custom fabrication. In the meantime, a plastic temporary crown is placed on the prepared tooth.
When the custom fitted crown returns from the lab, the dentist removes the temporary crown & cements the permanent crown.
