Sometimes, crowns fall out. In
some cases, a crown may come loose because there is decay underneath it. After
crowning a tooth, decay often starts near the gum line where the crown and
tooth meet. The decay destroys part of the tooth, so it no longer has a tight
hold on the crown.
Sometimes and inevitably, crowns
fall off. Usually, this is due to an improper fit, a lack of cement, or a
slight amount of tooth structure remaining that the crown can hold on to.
Sometimes are due to poor
workmanship, some are due to the tooth itself. There wasn’t enough tooth
structure to hold onto the crown. Sometimes the teeth are so short that when
tooth is prepared them for a crown, there’s not much tooth left for the crown
to “grab on to” when it is finally in place. This is more common in back teeth
that have been worn down over years of use and are short.
Sometimes eating too much sticky
foods. Generally speaking, people with artificial or restored teeth should
avoid eating sticky foods. Chewing sticky foods like chewing gums, some sticky
chocolates can gradually loosen your crown as you consume them. Eat enough
sticky foods and your crown might even fall out. If a crown becomes loose due
to sticky foods, it can be recemented.
Sometimes the crown is broken or
otherwise damaged. While crowns consist of durable materials, still these are
not as strong as your natural teeth. The truth is that the enamel of teeth is
the strongest part of entire body. Habits like chewing on hard items or
grinding teeth can fracture a crown over time. When a crown is damaged, the
only solution is to replace it with a new one.
Sometimes it is due to poor
shaping and faulty impression taking by dentist. The shaping crown is highly
skilled work, if tooth to be crowned is improperly shaped, poorly defined
margin placement is strong reason to fall out crown. The improper margin
shaping is strong reason results in improper fit of crown and leakage between
crown and tooth, eventually results in caries underneath tooth and of
inflammation gums near margin.
Sometimes it is due to poor
fabrication of dental technician. The latest CAD-CAM technology is best
solution which minimize the human errors to fabricate the crown in dental
laboratory.
The quality and technique to use of cement is also important factor.
