Health. All-ceramic veneers have excellent light transmittance, and the teeth can be prepared flush with the gums, which is beneficial to protecting the gums, making impressions, and bonding porcelain veneers. The area where porcelain veneers connect to the gums is only on the labial side, which causes less irritation to the gums, and there is no discoloration of the gums caused by metal ions from metal porcelain teeth. There are many different colors of porcelain blocks to choose from when making porcelain veneers, and external dyeing can be used to fine-tune the color. During clinical bonding, there are five different shades of adhesives and white shading agents that can be used to assist in adjusting the color of the porcelain veneers to achieve an overall coordinated cosmetic effect.
