Metal-alloy crowns – these are typically a mix of gold blend with another metal such as silver, platinum, copper, palladium or tin.
Porcelain-fused-with-metal crowns – these types of crowns are composed of a thinner porcelain wrapping around a metal based that is fused to the remaining tooth. This option gives your dentist a better opportunity to match the outer porcelain to the shade of your surrounding teeth. These offer a more natural look than full metal crowns.
Full metal-free crowns – non-metal crowns are growing to be the most popular, and typically what your dentist will recommend. These are fabricated from materials such as alumina, leucite, zirconia and porcelain. These non-metal crowns are best for a natural appearance and should last the longest.
