Dental Crowns:
A dental crown is a tooth-shaped cap that is placed over a damaged or decayed tooth to restore its shape, size, strength, and appearance. Crowns can be used to restore a variety of dental problems, including large fillings, broken teeth, and teeth that have undergone root canal treatment. A crown is usually recommended when a tooth has been damaged by decay or trauma, but the root is still intact and healthy. Crowns are highly durable and can last for many years with proper care.
There are several types of dental crowns available, and the choice of crown material will depend on various factors, including the location of the tooth, the amount of tooth structure remaining, the aesthetic concerns of the patient, and the preference and expertise of the dentist.

Here are some common types of dental crowns:

• Porcelain crowns: These crowns are made of a tooth-colored porcelain material that closely resembles natural teeth in appearance. They are often used to restore front teeth or teeth that are visible when smiling.
  
  
• Ceramic crowns: These crowns are made of a translucent ceramic material that is highly aesthetic and can closely mimic the appearance of natural teeth. They are often used to restore front teeth or teeth that are visible when smiling.
  
  
• Metal crowns: These crowns are made of metal alloys, such as gold or silver, and are highly durable and long-lasting. They are often used to restore molars or teeth that are subject to heavy chewing forces.
  
  
• Porcelain-fused-to-metal (PFM) crowns: These crowns are made of a combination of porcelain and metal, with the metal providing strength and the porcelain providing an aesthetic appearance. They are often used to restore both front and back teeth.
  
  
• Zirconia crowns: These crowns are made of a strong and durable ceramic material that is highly resistant to chipping and cracking. They are often used to restore molars or teeth that are subject to heavy chewing forces.
