Types of Dental Crowns
- Stainless steel crowns are silver in color. They don’t last as long as other metal crowns, so dentists use them on adolescent teeth mostly.
- Gold alloy dental crowns contain a combination of gold, copper, and other metals. Gold alloy is strong and will not break. It will also not wear away the underlying tooth.
- Base metal alloy crowns resist corrosion and are also very strong. The metals are gentle against other teeth and your dentist removes only a minimal amount of the tooth structure.
- Ceramic and porcelain-based crowns primarily restore front teeth. Their natural color and texture blend easily with your natural teeth, but porcelain crowns get brittle under the biting force of molars.
- Resin crowns are less expensive than other crown types. However, they wear down over time and are more prone to fractures.
What to Expect at Your Appointment
Preparing a tooth for a crown usually requires two visits to your dentist. The first appointment requires examining and preparing the tooth. The dentist will take X-rays to check the roots of the tooth and the surrounding bone. If the tooth has extensive decay or if there is a risk of infection or injury to the tooth’s endodontium or pulp, a root canal treatment may need to be performed before a dental crown can be placed on the tooth.
At the second visit, your dentist will remove the temporary crown and check the fit and color of the permanent crown. If everything is acceptable, your dentist applies a local anesthetic to numb the tooth and permanently cements the new crown in place.
