If you want a smile that's your crowning glory, you may need a crown to cover a badly decayed tooth,fractured tooth, protect and strengthen the tooth, or to help restore it to its normal shape and size.
A crown can help strengthen a tooth with a large filling when there isn't enough tooth remaining to hold the filling. Crowns can also be used to attach bridges, protect a weak tooth from breaking or restore one that's already broken. A crown is a good way to cover teeth that are discolored or badly shaped.
A crown (often called a cap) covers the tooth and restores it to its original shape and size. Decay is removed and cleaned from the tooth and a preformed crown is placed over the tooth. Unlike adult crowns, in which the crown is made to fit the tooth, which require 2 appointments, baby crowns are placed in one visit, because the tooth is prepared to fit the crown.
Advantages to crowns are they are incredibly strong due to the fact that they cover the entire tooth. This protects and strengthens the remaining tooth structure. They are the best chance for survival of a tooth that has had a baby root canal.
There are few disadvantages with crowns, however most children's crowns are silver in color.
Typically there are no good alternatives to crowns. If the tooth has sustained enough damage to require a crown then the best prognosis for the tooth is to receive the crown. Placing a filling on a tooth that should have a crown will likely result in fracture, recurrent decay, and loss of that tooth.
