Dr. Ghasaq Al-Bakkal of the Belmont Dental Clinic in London, Ontario promotes dental hygiene and offers cosmetic options such as zirconium crowns. Zirconium crowns have several advantages over porcelain crowns: they look natural with translucent color that can be adjusted, avoid the black line around porcelain crowns, are at least five times stronger and less prone to breaking or chipping, and are biocompatible with the body over many years. Proper dental hygiene is still needed with zirconium crowns to prevent decay of supporting tissue.
