Crowns and Bridges in BellevueTeeth that are chipped, cracked or have minimal natural tooth structure may need to be preserved with a full-coverage crown. Our office offers the following types of crowns: all-ceramic porcelain, zirconium, porcelain fused to high-noble metal and gold crowns. If a tooth or teeth are missing, a bridge may be necessary to fill in the space(s). Bridges stabilize the teeth, improve esthetics and provide the necessary surfaces for biting and chewing.
