A dental crown is used to strengthen a weak tooth or to restore a tooth that is heavily damaged. A tooth with a lot of decay should not have many dental fillings because there is an increased risk of the dental fillings failing. It is best for that tooth to have a dental crown instead. A weak tooth that is prone to fracturing becomes stronger when a dental crown is placed on top. Dental crowns are also placed on top of dental implants. However, the process requires two dental visits and a temporary dental crown is placed in between the visits.
