What is a permanent crown?
A permanent crown, also known as a dental crown, is a tooth-shaped cap that is placed over a tooth to restore its shape, size, strength, and appearance. Crowns are often recommended by dentists to cover damaged, decayed, or misshapen teeth, and they can also be used to hold a dental bridge in place or cover a dental implant. In this article, we will explore the types, benefits, and procedures involved in getting a permanent crown.
The need for a permanent crown usually arises from various dental conditions. For instance, a tooth may have been weakened by decay, causing it to be more susceptible to fractures. A tooth may also be malformed or discolored, requiring a crown to improve its appearance. Additionally, crowns can be used to protect a tooth that has had a root canal treatment, as the crown can help to reinforce the tooth and prevent it from breaking.
There are several types of permanent crowns available, each with its own advantages and applications. The most common types include:
1. Porcelain-fused-to-metal crowns: These crowns combine the natural look of porcelain with the strength of metal. They are often used when a tooth requires both aesthetics and durability.
2. All-porcelain crowns: These crowns are made entirely of porcelain, making them an excellent choice for patients who want a tooth-colored restoration. They are ideal for front teeth and can be customized to match the surrounding teeth.
3. Gold crowns: Gold crowns are known for their exceptional strength and durability. They are often used for molars, as they can withstand the forces of chewing and biting.
4. Ceramic crowns: Ceramic crowns are another tooth-colored option, similar to all-porcelain crowns. They are often used for front teeth and are known for their natural appearance and biocompatibility.
5. Stainless steel crowns: These crowns are typically used as temporary crowns until a more permanent option can be fabricated. They are also commonly used for children’s teeth, as they can withstand the wear and tear of a developing mouth.
The process of getting a permanent crown typically involves several steps:
1. Consultation: The first step is to consult with a dentist to determine if a crown is the right treatment option for your dental needs.
2. Preparation: During the preparation phase, the dentist will remove any decayed material and shape the tooth to fit the crown. An impression of the tooth will be made, which will be used to create the custom crown.
3. Temporary crown: A temporary crown will be placed on the prepared tooth while the permanent crown is being fabricated. This temporary crown will protect the tooth and prevent sensitivity.
4. Crown fabrication: The impression of the tooth will be sent to a dental laboratory, where the permanent crown will be crafted to fit the tooth’s unique shape and size.
5. Crown placement: Once the permanent crown is ready, the dentist will remove the temporary crown and cement the new crown in place. The dentist will then check the fit and make any necessary adjustments to ensure a comfortable and functional bite.
In conclusion, a permanent crown is a dental restoration that can help improve the health, appearance, and functionality of a tooth. By understanding the different types of crowns and the procedure involved, patients can make informed decisions about their dental care. If you are considering a permanent crown, consult with your dentist to determine if it is the right treatment option for you.
