Metal crowns give the most precise fit of all crown types since they are very flexible. The preparation of a tooth for a metal crown is the simplest and least complicated preparation for the dentist since there is minimal tooth structure removal. This allows for a large portion of the healthy tooth structure to remain untouched. Metal crowns also do not cause wear on opposing teeth over time. There is no possibility of chipping and they offer a healthier environment for the gum tissue.
Although their metallic color makes them a poor choice for highly visible teeth, dental crowns made of metal can be an ideal option for repairing decayed or damaged back teeth. They are extremely durable and can be applied with less removal of the natural tooth than all porcelain or ceramic crowns. Metal crowns may consist of various materials, including gold alloy, palladium, nickel alloy, or chromium alloy.
Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down. Also, metal crowns rarely chip or break. The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight molars.
The degree to which this type of event is a problem will vary. Some problems are loss of tooth function, compromised cosmetic appearance, or the creation of a situation that makes maintaining oral hygiene difficult. The porcelain lost from a PFM crown cannot be reattached or replaced with new metal. It can be possible that dental bonding can be used to make a patch, although the long-term success of this type of repair is tentative. If the chip is just minor, no repair may be needed. At the other extreme however, a broken crown may need to be replaced with a new one.
