Types of Dental crowns and their description:
1. All- Porcelain Crown – this type of crown is best for front teeth as they can be color-matched to your teeth and looks exactly like natural teeth. However, this type can easily chip or break causing a wearing down of adjacent teeth. It is suitable for people with allergies to metal.
2. All-Metal Crown – this crown type uses gold alloys or nickel or chromium or another metal-based alloy. it lasts longer than any other crown type as it can endure biting and chewing forces and they seldom if not rarely break. It is the best choice for cannot-be-seen teeth like molars.
