Dental crowns are caps that are placed over your teeth from the top to your gums. They are often used to cover teeth that are broken or worn down. They can also be used to improve the appearance of teeth with severe discoloration. Other reasons for crowns:
protecting weak teeth; supporting teeth that have very large fillings; covering dental implants, keeping a bridge in place; covering teeth that have had root canals…
Dental crowns generally last between five and 15 years, depending on which type you get. Metal crowns are very durable and often used on back molars. Porcelain and ceramic crowns have a more natural appearance than metal, although they are not as strong. Either one is a good choice if you need a front tooth covered. Resin crowns are typically the least expensive option. If you want the best of both worlds, porcelain-fused-to-metal crowns offer a natural look and durable quality.
