How do I know when it’s time to replace old dental crowns?
Dental crowns are intended to protect natural teeth that have been weakened by providing a tough, durable casing of high-grade dental porcelain around the tooth. Over time, these crowns can wear down just like your natural tooth and may need replacing. If you have a PFM (porcelain-fused-to-metal) crown, eventually you may start to notice a black line between the tooth and the gum tissue. You may choose to upgrade to a new porcelain crown whenever you feel your crown appearance or functionality has been compromised.
What are the advantages of working with iTero™ digital impressions?
With guidance from a 3D digital image, our dental lab has a very precise and detailed map to use for the creation of your new restoration. This high level of precision helps us deliver tooth crowns that successfully meet your functional and appearance goals. Since the addition of the iTero system, we have been able to provide our dental crown patients with results that far surpass the crowns produced years ago.
What is the difference between a tooth colored filling and a porcelain dental crown?
A dental filling is used when a tooth has been affected by bacterial growth (a cavity). Calgary dentists Dr. Sahra Kanji and Dr. Mehbs Ali removes the damaged portion of the tooth and fills in the space with a tooth-colored composite material. A dental crown fits over the whole tooth and is recommended when the area of decay is too large to contain with a filling. Dental crowns may also be used when a tooth has suffered trauma from physical injury and requires strong protective measures.
Why is porcelain considered the ideal dental crown material?
Porcelain contributes many beneficial qualities to a dental crown restoration. Our tooth-colored porcelain material is translucent, reflecting light in much the same way as natural tooth enamel. This allows us to choose a distinct shade of porcelain to complement your natural shade. Porcelain is also very durable when bonded well, and it is resistant to breakage and staining.
