Dental crowns are a common restorative procedure used to protect and strengthen damaged or weakened teeth. They're essentially tooth-shaped caps that fit over the entire tooth, restoring its shape, size, strength, and appearance. But why are they necessary? Let's delve into the reasons people choose to get dental crowns.
What are the Main Reasons for Getting a Dental Crown?
The primary reasons for needing a crown revolve around protecting and restoring a compromised tooth. These include:
-
Significant Tooth Decay: When a cavity is too extensive to be repaired with a simple filling, a crown becomes necessary to cover the weakened tooth structure and prevent further damage. A large filling can also weaken a tooth, making a crown a preventative measure.
-
Cracked or Broken Teeth: Teeth that have fractured or chipped significantly often require crowns to hold the remaining pieces together and prevent further breakage. This is particularly important for teeth that are under significant stress, such as molars used for chewing.
-
Root Canal Treatment: After a root canal, the tooth becomes brittle and more susceptible to fracture. A crown provides crucial protection and structural support, helping the tooth last much longer.
-
Large Fillings: If a tooth has a very large filling, it may become weak and prone to cracking. A crown will encompass the remaining tooth structure and provide strength and stability.
-
Cosmetic Purposes: While primarily restorative, crowns can also improve the appearance of a tooth. They can correct discoloration, shape irregularities, or gaps between teeth. This is especially important for front teeth where aesthetics are a major concern.
-
Protecting Teeth After Dental Implants: Crowns are commonly placed on top of dental implants to restore the appearance and function of a missing tooth.
-
Teeth Grinding (Bruxism): For people who grind or clench their teeth (bruxism), crowns can protect teeth from excessive wear and tear. They act as a protective barrier against the forces of grinding.
What are Dental Crowns Made Of?
Dental crowns can be made from various materials, each with its own advantages and disadvantages:
-
Porcelain: Known for its aesthetic appeal, matching the natural color of teeth very well. It's durable but can be more prone to chipping than other materials.
-
Porcelain Fused to Metal (PFM): A strong and durable option that combines the strength of metal with the aesthetic qualities of porcelain.
-
Metal: Highly durable and resistant to wear and tear, often used for molars where strength is prioritized over aesthetics. Gold, alloys of different metals, and even base metals are utilized.
-
Zirconia: A strong, biocompatible, and highly aesthetic material that is becoming increasingly popular due to its strength and natural look.
How Long Do Dental Crowns Last?
With proper care and maintenance, dental crowns can last for many years, often 10-15 years or even longer. However, factors such as oral hygiene, diet, and the underlying health of the tooth can influence their lifespan. Regular dental checkups and professional cleanings are crucial for maintaining the longevity of dental crowns.
What Happens During a Crown Procedure?
The process typically involves two appointments. The first appointment involves preparing the tooth by removing some enamel, taking impressions for the crown, and placing a temporary crown. The second appointment involves removing the temporary crown and cementing the permanent crown in place.
Are Dental Crowns Painful?
Most patients report minimal discomfort during the procedure. Local anesthesia is typically used to numb the area, making the process painless. Some mild sensitivity might be experienced after the procedure, but this usually subsides quickly.
How Much Do Dental Crowns Cost?
The cost of dental crowns can vary depending on the material used, the dentist's fees, and insurance coverage. It's best to discuss the costs with your dentist directly to get an accurate estimate.
This comprehensive overview should provide a clear understanding of why people get crowns on their teeth. Remember, consulting a dental professional is crucial for determining the appropriate treatment plan for your specific needs.
