High Gold Dental Crowns: Durability, Costs, and Concerns - Dentistry

Regarding gold dental crowns?


Hello Dr.
Chuang,
I have a few questions to ask:
1.
Is the lifespan of dental fillings made from resin materials relatively short, around 2 to 5 years, before they become susceptible to moisture and lead to secondary caries?
2.
Does health insurance typically only cover silver amalgam and resin materials for fillings?
3.
If high-gold crowns are used, are they more durable and have a longer lifespan compared to other materials?
4.
Is there a higher likelihood of experiencing sensitivity with high-gold crowns in the initial period compared to other filling materials?
Thank you for your assistance.

Hello: 1.
All recurrent caries are significantly related to oral hygiene.
Regardless of the material used for fillings, improper cleaning can lead to recurrent caries.
There are clinical cases where resin-based fillings have lasted a long time.
2.
There are also glass ionomer cements.
3.
The material you mentioned is metal, which theoretically has better durability, but it is still greatly influenced by oral hygiene.
4.
Metal has strong conductivity, so it can also be more sensitive.

When considering dental restoration options, particularly high gold dental crowns, it is essential to understand their durability, costs, and any potential concerns associated with their use. Here’s a comprehensive overview based on your questions.

1. Durability of Resin Fillings: Resin materials, often used for dental fillings, typically have a lifespan of about 5 to 10 years, depending on various factors such as the location of the filling, the patient’s oral hygiene practices, and the size of the filling. While it is true that resin fillings can be more susceptible to wear and tear compared to metal options, they do not inherently lead to secondary decay (cavities) if maintained with proper oral hygiene. The risk of secondary decay is more closely related to how well a patient cleans their teeth and maintains regular dental check-ups. If a resin filling is placed correctly and the patient practices good oral hygiene, it can last longer than the average lifespan.

2. Insurance Coverage: In many countries, including the United States, dental insurance often covers basic restorative materials such as amalgam (silver fillings) and composite resin fillings. However, coverage for more expensive materials, such as high gold crowns, may be limited or not covered at all. Patients should check with their specific insurance provider to understand what is covered under their plan. Some plans may only cover a portion of the costs for more expensive materials, leaving the patient responsible for the difference.

3. Durability of High Gold Crowns: High gold crowns are known for their exceptional durability and longevity. They can last 15 years or more, and in some cases, even longer with proper care. The high gold content provides strength and resistance to wear, making them an excellent choice for areas of the mouth that experience significant chewing forces. Additionally, gold crowns are less likely to fracture compared to porcelain or resin materials. However, the longevity of any dental restoration is still influenced by factors such as oral hygiene, diet, and regular dental visits.

4. Sensitivity with High Gold Crowns: It is common for patients to experience some sensitivity after receiving a new crown, regardless of the material used. This sensitivity can be due to several factors, including the preparation of the tooth, the fit of the crown, or the material itself. High gold crowns may have a different thermal conductivity compared to other materials, which can lead to increased sensitivity to hot or cold temperatures initially. However, this sensitivity typically diminishes over time as the tooth adjusts to the new crown.

In conclusion, when choosing between dental restoration options, it is crucial to weigh the benefits and drawbacks of each material. High gold crowns offer excellent durability and longevity, making them a worthwhile investment for many patients. However, individual circumstances, including budget, insurance coverage, and personal preferences, will also play a significant role in the decision-making process. Always consult with your dentist to discuss the best options tailored to your specific dental needs and conditions. Regular dental check-ups and maintaining good oral hygiene are essential for the longevity of any dental restoration.
