If you need to crown a tooth, then you have a choice of materials. While many people choose porcelain crowns, other materials, such as zirconia, have some advantages that might make them a better choice.
What are the benefits of zirconia crowns?
1. Extra Strength
While all crowns are designed to be strong and stable, these false teeth can get damaged just like your natural teeth. For example, crowns can chip, fracture, and even break. If you have an oral habit, say if you grind your teeth, then your habit can also wear down or damage a crown.
Zirconia crowns are strong and resilient. They are more likely to stand up to the stress of being in your mouth, even on your back teeth which have to deal with stronger chewing forces.
Plus, zirconia is better able to deal with problems such as grinding. It wears less than materials such as porcelain. If you've had problems with a crown in the past because you grind your teeth, then it's worth switching to zirconia in the future.
2. More Stain Resistance
While crowns are made from artificial materials, they can still stain just like real teeth. For example, crowns made from acrylics can stain or pick up color if you drink a lot of tea, coffee, or red wine. They will eventually stain if you smoke.
While no crown material can completely resist lifestyle color changes, zirconia crowns beat other crowns here. They keep their initial color more effectively as they age. They are less likely to stain or change color.
3. Better Biocompatibility
Some people have adverse reactions to some crown materials. For example, metal or porcelain-fused-to-metal crowns are sometimes a problem. People can find that they have a sensitivity to these crowns or that they experience allergic reactions to their metal content.
Zirconia is a biocompatible and hypoallergenic material. Even people with allergies can tolerate these crowns without any problems.
4. Easier Modification
If your crown doesn't fit well when your dentist fits it, then they might have to send it back to the lab for modification. They might not have the tools to make more than minor changes.
Dentists can make changes to zirconia crowns themselves. If your crown doesn't fit exactly at your fitting, then they can modify it on the spot. If you feel that the fit isn't quite right after you've worn the crown for a while, then they can reshape it in your mouth.
