When Are Crowns Necessary?
We use dental crowns for several situations. A crown is most commonly used to protect a weak tooth from breaking. For instance, a cracked or decayed tooth can be held together using a dental crown. Crowns can also be used to restore a tooth that is severely worn down. If a large filling falls out, or there is not a lot of tooth left, Dr. Walmsley may repair it with a crown. Other uses include:
|•||Holding a dental bridge in place
|•||Covering a severely discolored tooth
|•||Covering a severely misshaped tooth
|•||Covering a dental implant
|•||Covering a root canal
|•||Make some other cosmetic alteration|
Types of Crowns
Crowns can be made from several materials including, ceramic, resin, porcelain and metal, gold, silver amalgam, or stainless steel.
Ceramic or porcelain crowns have become increasingly popular in recent years. Thanks to technological advancements, porcelain can support a stronger bite force than ever before. Porcelain also provides a more natural color match than other crown alternatives. These days, porcelain crowns can be used for front and back teeth.
Resin crowns are the least expensive; however, they do wear down much faster than other options. They are also more prone to fractures.
Next to all-porcelain crowns, porcelain and metal crowns look most like your natural teeth. The underlying metal can show through in certain cases, but the metal provides additional strength. These crowns are a great choice for back teeth that need additional support.
Gold and silver amalgam crowns can withstand the forces of chewing very well and usually last the longest. Although they are less common today, they are a good choice for out-of-sight molars. Metal crowns offer unmatched durability when it comes to these teeth.
Stainless steel crowns are prefabricated and usually a temporary solution. Children may need to receive a stainless-steel crown to protect a primary tooth, and ensure a health eruption of their permanent one.
A dental crown requires a minor procedure that is usually split up into two visits. During your first appointment, Dr. Walmsley will completely reshape your tooth, removing a large portion of enamel to accommodate the crown. Next, an impression of the new shape will be taken and sent to a dental laboratory, where they will fabricate your crown. This process may take several weeks. In the meantime, we will give you the temporary crown.
At your second appointment, we will remove the temporary and check the margins of your new crown. We may need to make some minor adjustments to ensure the perfect fit. Once Dr. Walmsley is happy with the results, your crown will be permanently cemented into place.
Under the right care and maintenance, your crown will last 15 years or longer. Dr. Walmsley will give you a detailed list of instructions before you leave the office.
