Older porcelain crowns often chip or wear, leaving the fused metal base exposed. The area of the crown near the gumlines often leaves an exposed metal line along the tooth as well. This can appear dark and grey, leaving the patient self conscious of how their smile appears.
There is a way to avoid metal showing when you smile. All-porcelain crowns are a type of dental restoration that does not use any metal base for its fabrication. The entire crown is made of tooth-colored material so that no matter where it is placed in the mouth, you will not have to worry about metal showing. This is beneficial for patients who grind their teeth, or need to have their bites adjusted.
All-porcelain crowns also appear more natural in color than traditional crowns. Because teeth are actually more than one shade, porcelain crowns can use two or even three shades throughout the tooth to make it a better match.
Crowns are essential in treating teeth with large, older, broken restorations or large areas of decay. When a tooth has broken down so much, then thin outer shell of enamel is not enough to support a filling. Instead, crowns cover the entire surface of the tooth allowing it to hold up to normal uses like chewing. This distributes the pressure equally over the tooth and allows it to last years to come.
Some people also find that they are sensitive to certain metals. Tissue irritation and bleeding may occur. Because all porcelain crowns contain no metal, they are a wonderful option for these patients.
If you are in need of a crown, or have metal crowns and are thinking of having them replaced, consider all porcelain crowns. They function just as efficiently as other crowns but are much more aesthetically pleasing and easier on the delicate gum tissues.
