Inlays are an excellent and conservative way to protect, strengthen, and preserve tooth structure. Inlays can be made from gold alloys, pressed composite materials, or porcelain. Inlays are used to provide a strong replacement for large weakened fillings in posterior teeth and replacement of broken corners of teeth. Porcelain and composite inlays are a wonderful way to esthetically replace large fillings in weakened teeth when full crowns are not needed. They are also an excellent non-metal alternative for patients desiring to keep their teeth metal free.
