Compared to fillings which just cover a small portion of a tooth, a crown (or cap) encases the entire visible portion of a tooth. In effect, the crown acts as the tooth's new outer surface. A dental crown is used when a tooth is broken or decayed to such an extent that fillings aren't able to repair the problem. The crown is able to provide a protective shell around the damaged or decayed tooth to strengthen it, as well as to improve the appearance of the tooth. They can also help restore a tooth to its original shape and are used commonly for teeth that have been broken.
What to expect:
Prepping the tooth for a crown can take a few visits. Typically, a portion of the tooth will have to be removed for the crown to fit properly. After the tooth has been reshaped, the dentist will size your child’s tooth and then order the crown that best fits. Before cementing the crown in place, the dentist will ensure that it fits comfortably.
