Dental Crowns: Gold vs. Non-Gold Options and Longevity - Dentistry

More Info

---

When considering dental crowns, particularly the choice between full gold crowns and those containing 20% gold, several factors come into play, including longevity, aesthetics, biocompatibility, and cost.
Longevity of Gold Crowns:
Full gold crowns are known for their exceptional durability and longevity. They can last anywhere from 10 to 20 years or even longer with proper care. This is primarily due to gold's resistance to wear and its ability to withstand significant chewing forces without fracturing. On the other hand, crowns with 20% gold, which typically consist of a mix of metals, may have a slightly shorter lifespan, generally lasting around 5 to 15 years. The longevity of any crown, however, is highly dependent on factors such as oral hygiene, the location of the crown in the mouth, and the patient's overall dental health.

Impact of Cavities:
If a crown becomes compromised due to decay underneath it, it may need to be replaced. In cases where a cavity forms beneath a crown, the dentist will assess whether the tooth can be salvaged. If the tooth structure is still intact and healthy, the dentist may be able to treat the decay and place a new crown. However, if the tooth is significantly damaged, extraction may be necessary, followed by the placement of an implant or bridge.

Biocompatibility Concerns:
Regarding biocompatibility, full gold crowns are generally considered safe and biocompatible, meaning they are less likely to cause allergic reactions or other adverse effects in the body. Gold is a noble metal, which means it does not corrode or react with bodily fluids. Crowns that are not made of pure gold may contain other metals, which could potentially lead to allergic reactions in some individuals. However, the risk is relatively low, especially with high-quality dental materials.
Cost Considerations:
From an economic perspective, full gold crowns tend to be more expensive than those with lower gold content due to the higher material costs. However, considering their longevity and durability, full gold crowns may offer better value over time, as they are less likely to require replacement.
Aesthetic Considerations:
While gold crowns are incredibly durable, they are not the most aesthetically pleasing option, especially for visible teeth. Many patients prefer porcelain or ceramic crowns for their natural appearance. These materials can closely mimic the color and translucency of natural teeth, making them a popular choice for front teeth. However, they may not be as durable as gold crowns, particularly in areas subjected to heavy chewing forces.

Conclusion:
In summary, when choosing between full gold crowns and those with 20% gold, consider the longevity, biocompatibility, cost, and aesthetic preferences. Full gold crowns offer superior durability and biocompatibility, making them a worthwhile investment for many patients, especially in posterior teeth where strength is paramount. However, for anterior teeth, where aesthetics are more critical, porcelain or ceramic options may be more suitable. Always consult with your dentist to evaluate your specific dental needs and preferences to make the best choice for your oral health.
