Whenever you have a tooth or teeth missing, a bridge could be a good treatment option. A bridge has 3 or more crowns connected together. The crowns in the middle of the bridge fill in the space for the missing tooth or teeth. Once teeth on either side of the missing tooth or teeth are prepared, an impression is taken. Once the bridge comes back from the dental laboratory, it is permanently cemented in the mouth. Bridges can be made in all porcelain, porcelain and metal, or all metal.
