Porcelain Crowns
When a tooth is cracked, decayed, or damaged, a crown may need to be fitted onto
the tooth. A crown is a permanent covering that fits over the original tooth. Crowns
can be made of porcelain, gold and other metals, acrylic resin, or an amalgam (a
mix) of these materials. Porcelain crowns typically have the most realistic appearance,
although they tend to be less durable than other materials. Crowns can whiten, reshape,
and realign existing teeth, adding to a healthy and vibrant smile.
Preparation
During your first visit, the dentist will numb the tooth to be crowned and remove
the decay in or around it. The tooth is then rescultped to provide an easy fit for
the crown. This is a painless process that is performed in the dentist's chair.
An impression of your teeth is then taken and sent to the dental lab where permanent,
custom-made crowns are created (this usually takes one to two weeks). During this
interim period, temporary crowns made of an acrylic resin are fitted onto the teeth.
Applying the Crown
On your next visit, the dentist removes the temporary crown and fits the permanent
crown onto the teeth. He or she makes sure the crown has the proper look and fit,
and then cements the crown into place.
Maintainance
The proper dental hygiene for normal teeth should be applied to your new crown.
Daily brushing and flossing will help to keep the teeth, gums, and new crown free
from the bacteria that can cause gum disease. Avoid chewing on hard foods such as
ice or pistachios, which, over time, can cause crowns to crack or break. Given proper
care, crowns can last several decades, and may last a lifetime.
