Porcelain crowns have several benefits for patients. They can restore a natural appearance when a tooth is damaged by accident or when its enamel is badly eroded by tooth decay or other causes. They are also used when grinding has compromised the integrity of a tooth. Crowns cover a defective or unsightly tooth from the tips to the gum line, taking the place of old fillings and matching the tooth’s original color.
Being fitted with a crown requires multiple visits to a dental office. It takes time for laboratories to make them, so dentists fit patients with a temporary crown.
Porcelain crowns do have some drawbacks. Some patients report sensitivity to hot and cold foods. Although crowns are durable, natural teeth are more flexible, and patients may have to avoid certain foods. A mouth guard may be necessary to preserve the porcelain from pressure by those who grind their teeth or clench their jaws during sleep.
