Crown and bridgework is a very reliable solution for major dental problems caused through accidents, diseases or wear and tear. Major problems can usually be corrected using these techniques. Material used in these repairs is either high-grade porcelain or porcelain bonded to gold. A higher strength of the porcelain and gold materials is recommended to treat the most serious of dental problems. Where accidental damage has occurred, resulting in lost teeth, or where teeth have broken away through excessive wear, or as the result of old fillings breaking, dental crowns and/or dental bridges can be used as a long-term solution.nnMany people have unexplained pain from filled back teeth, which is usually due to hairline cracks in the chewing part of the tooth. Placing crowns on these teeth relieves the pain and allows a return of full dental function for these teeth. In front teeth, older fillings can both weaken the teeth and cause “appearance” problems due to staining or chipping. Porcelain crowns and bridges are suitable in cases where porcelain veneers are not. In teeth with root canal fillings, dental crowns can prevent breakage.
