When a tooth is cracked, decayed, or damaged, a dental crown may need to be fitted onto the tooth. A dental crown is a permanent covering that fits over the original tooth. Crowns can be made of porcelain, gold or a combination of both materials. Porcelain crowns typically have the most realistic appearance, although they tend to be less durable than other materials when used on your back molars. Dental crowns can whiten, reshape and realign existing teeth, adding to a healthy and vibrant smile.
The preparation of a tooth for a gold crown is the simplest and least complicated preparation. There is minimal tooth structure removal with as much as possible of the healthy tooth structure remaining untouched. While porcelain is hard by comparison, it may cause wear on opposing teeth over the years, where gold is not as likely to do so. Gold is also easier to fit to the area where the tooth and crown meet for a better fit. Gold is also a healthier environment for the gum tissue.
