Crowns Q & A
What Is a Dental Crown?
A dental crown is a prosthetic cap that is placed over a tooth to improve appearance and functionality by restoring the tooth’s size, shape, color, and strength. Crowns are permanent and therefore cannot be removed. A crown will look like a normal part of your mouth as your own teeth. Crowns are normally used to cover damaged teeth, and because they fully extend to the gum line, no one can tell they are not part of your natural teeth.
Why Does Someone Need a Dental Crown?
Crowns are needed for cosmetic and restorative purposes. The most common reason for a crown is because a tooth has been broken or decayed and there is not enough tooth left to be eligible for a filling. Crowns can also be used to add support to weakened or fractured teeth to prevent them from breaking further.
Crowns can also be used in conjunction with other dental procedures such as bridges and dental implants. Crowns are the support that holds a dental bridge in place and are usually placed on the teeth surrounding the bridge. In a dental implant, crowns are attached to the abutment to cover the implant and therefore restore lost teeth.
What Are the Different Types of Crowns?
Crowns can be made using a variety of materials, including stainless steel, metals like gold or nickel, porcelain-fused-to-metal, full resin, and full ceramic or porcelain.
- Stainless steel is the easiest and cheapest material to use. This material is typically used for children’s crowns.
- Gold lasts the longest and is preferred for use on molars because they are not tooth-colored.
- Porcelain-fused-to-metal offers a realistic look as porcelain matches the color of your teeth and can be used in the front or back.
- The full resin is inexpensive but will wear down over time.
- All-ceramic looks the most natural but degrades the surrounding teeth over time.
