Different Types of Crowns
Crowns are made from various types of materials. Depending on which tooth needs a crown, your dentist will suggest a material, or combination of materials, that is right for you.
Metal Crowns are made of gold. They generally last a long time and won’t chip or break. They tend not to wear down your opposing natural teeth. However, the gold colour does not look natural, particularly on front teeth.
Composite Crowns look natural. They won’t chip as easily as porcelain crowns, but they tend to wear more quickly from chewing. Tooth brushing tends to remove the highly polished surface of composite crowns and this causes them to stain more easily.
Porcelain Crowns look the most natural. They are more brittle than metal or composite and may chip more easily. Because of this, they are not usually placed on back teeth.
Porcelain-fused-to-metal Crowns look natural and are stronger than porcelain or composite crowns. They won’t chip as easily as porcelain or ceramic crowns. However, depending on their design, the metal may show if your gums are thin or shrink.
What Else Should I Know?
Crowns are strong and generally last for about 10 years or longer if you take good care of them. Brush and floss your crown, just like you clean your natural teeth. Crowns may not be as strong as your natural teeth. So like your natural teeth, remember not to bite down on hard objects or use your teeth to open or cut things.
