Loose Crowns

Mitchell Pohl, DDS, Boca Raton FL

Crowns (whether porcelain or acrylic-composite) that are cemented to an existing tooth can easily become loose if leakage occurs. Bacteria can move into the cementation interface and slowly destroy the underlying tooth.

With routine biting and chewing behaviors, it is not uncommon for a tooth to completely fall out. Patients have also been known to swallow loose crowns during sleep.

The most common reason "believed" to be the problem is faulty cement. In situations where leakage has not occurred, an occlusal event is usually the cause for a crown to loosen. Adjacent teeth that are not properly maintained can have wear issues that affect how opposing teeth operate upon a crown. If a lateral or sideways force is produced.... a properly cemented crown can fail.

Crowns that are mounted onto dental implants (cemented or screw retained) can fail due to cementation errors, lateral forces and failure of the dental implant (more >>>).

Any suspicion of a loose tooth on a dental implant warrants immediate treatment (if not today, tomorrow). A loose crown can move enough to cause lateral forces to operate "against" a dental implant which becomes immediately telegraphed to the bone tissue at the implant site.

Left untreated for even a short time, the implant can fail, requiring a new implant surgery often accompanied by additional bone grafting products.
