Dental crowns are a vital procedure in dental restorations, designed to support and fortify damaged or decayed teeth. They have been used for centuries, providing a durable solution for individuals with cracked, broken, or severely damaged teeth, but they are not always necessary. But when are dental crowns necessary, and how do they work?

A dental crown is essentially a cap made from a range of materials such as porcelain. These materials can be used in combination to create a strong, durable crown that matches the surrounding teeth. The tooth preparation involves the dentist shaping the affected tooth to fit the crown, which can take two appointments, depending on the complexity of the procedure.

There are several reasons why dental crowns are necessary. They strengthen a weak tooth:

• Support a weak tooth that would break easily
  
• Protect a tooth with severe decay that cannot be repaired
  
• Restore a tooth that has been damaged by injury
  
• Replace a tooth with a large filling that needs to be filled
  
• Improve the appearance of a misshapen tooth
  
  

Dental crowns work by providing an additional shield to the tooth. This prevents further damage and discomfort caused by biting. In addition, they enhance the function and appearance of the tooth, allowing patients to eat with confidence and peace of mind.

In some cases, dental crowns are used in combination with other treatments. For example, teeth that have been damaged by exposed roots may require a crown to support them, as well as a periodontal treatment to heal the gums. Similarly, teeth with missing or damaged fillings may require a crown in addition to a new filling.

When considering a dental crown, patients often have several options to select. Different types of crowns include:

• Metal crowns, which are usually made from gold

Ultimately, the choice of dental crown depends on the patient's specific needs and preferences. With proper care and maintenance, dental crowns can last for a long time, providing a durable and last-lasting solution for damaged or decayed teeth. If you are considering a dental crown, it is crucial to visit a a qualified dentist to determine the best course of treatment for your individual requirements.
