Quick Contact
A damaged tooth that is left untreated rarely improves on its own. A crack that starts small grows. A tooth weakened by decay or a large filling becomes susceptible to fracture under normal biting forces. When a tooth has been compromised to the point that a filling is no longer sufficient, a porcelain crown restores its full strength, protects it from further damage, and brings back its natural appearance.
At Lumin8 Dentistry in Lakewood, WA, Dr. Jun Carrington places custom porcelain crowns that fit precisely, look completely natural, and are designed to last. As a core part of our restorative dentistry services, crowns are one of the most versatile treatments we offer, addressing everything from severe decay to cracked teeth to worn-down enamel.
What Are Zirconia Crowns?
Zirconia crowns are tooth-shaped caps placed over injured or weakened teeth to restore their size, shape, strength, and appearance. Made from high-quality materials, these restorations mimic the translucency and color of tooth enamel better than most alternatives. The material creates a restoration that blends invisibly with surrounding teeth. These crowns serve multiple purposes, including the following:- They protect teeth that have undergone root canal treatment
- Hold together cracked teeth
- Restore severely worn teeth
- Anchor dental bridges
The Crown Placement Process
A zirconia crown usually requires two appointments. During the first visit, the dentist reshapes the injured tooth to create space for the crown. This preparation involves removing a small amount of tooth structure from all sides and the biting surface. After reshaping, the dentist takes detailed impressions of your teeth using digital scanning or traditional impression materials. These digital impressions are sent to a dental lab, where skilled technicians craft your custom crown. The process takes about two weeks, during which you’ll wear a temporary crown to protect the prepared tooth. At the second appointment, the dentist removes the temporary crown, checks the fit and color of your permanent restoration, and cements it permanently in place. Some dental offices now offer same-day crowns using CAD/CAM technology. This advanced system designs and mills crowns in-office, allowing you to receive your permanent restoration in a single visit.Materials and Durability
Modern zirconia crowns are one of dentistry’s most significant technological advances. This advanced ceramic material combines exceptional strength with natural aesthetics, making zirconia an ideal choice for virtually any tooth restoration. Unlike traditional materials, zirconia maintains its structural integrity while mimicking the translucent quality of natural enamel. Zirconia’s crystalline structure provides remarkable durability for back teeth enduring significant chewing forces. The material resists fracturing and wears better than many alternatives, making it suitable for molars and premolars. Front teeth benefit equally from zirconia’s ability to blend seamlessly with surrounding teeth while maintaining the strength needed for daily function. With proper care, zirconia crowns typically last 10 to 15 years, with many functioning well beyond that. Studies show that approximately 95% of dental crowns remain intact after five years when patients maintain good oral hygiene. Avoiding habits like teeth grinding, chewing ice, or opening packages with your teeth helps prevent damage and extends the life of your restoration.Benefits of Choosing Zirconia for Your Crown

When a Crown Is Recommended
Dr. Carrington recommends a crown when a tooth’s structure has been compromised beyond what a filling or cosmetic bonding can repair. Common situations include a large cavity that has destroyed too much tooth structure, a cracked or fractured tooth that is at risk of splitting, a tooth that has completed root canal treatment and needs protection, or a tooth that is severely worn due to grinding or acid erosion.
Crowns are also the final step in dental implant restoration, placed on top of the abutment to create the visible tooth. And as part of a dental bridge, crowns anchor the restoration on either side of a gap.
