FutureStarrWhat is a crown for teeth
Over time, your teeth can get damaged. This can happen for a variety of reasons, like tooth decay, injuries or just use over time. Your teeth can lose their shape or size. Dental crowns are tooth-shaped “caps” that can be placed over your tooth. Think of it like a snug hat for your tooth. The crown restores the tooth’s shape, size, strength and appearance.
There are many types of crowns that can be used on your teeth. Onlays and 3/4 crowns are types of dental crowns that don’t cover as much of your underlying tooth as traditional dental crowns. A traditional crown will cover your entire tooth. Onlays and 3/4 crowns may be appropriate when you still have a solid tooth structure. It’s considered a more conservative approach compared to full coverage of your crown. In this procedure, your dentist removes the affected area and performs a reshaping of the tooth to receive the crown.Metal: There are several metals that can be used in dental crowns, including gold, palladium, nickel and chromium. Metal crowns rarely chip or break, last the longest in terms of wear down and only require a small amount of your tooth to be removed. They can also withstand biting and chewing forces. The metallic color is the main drawback of this type of crown. Metal crowns are a good choice for out-of-sight molars.
All-ceramic or all-porcelain: These types of dental crowns provide the best natural color match compared to any other crown type. They’re also a good choice if you have metal allergies. However, they aren’t as strong as porcelain-fused-to-metal crowns. They can also wear down the teeth opposite them in the mouth a little more than metal or resin crowns. All-ceramic crowns are a good choice for front teeth.Pressed ceramic: These dental crowns have a hard inner core. Pressed ceramic dental crowns replace the metal liner that’s used in the all-ceramic crown-making process. Pressed ceramic crowns are capped with porcelain, which provides the best natural color match. They’re also more long-lasting than an all-porcelain crown. (Source: my.clevelandclinic.org)
