Dental fillings are used to repair damaged or decayed teeth and restore the tooth’s shape and function. Among the different types of fillings available, silver amalgam and white composite resin fillings are the most commonly used. Both types have their benefits and drawbacks. So, which dental filling treatment option is better for you? In this blog post, we’ll compare silver fillings vs white fillings to help you make an informed decision.
Comparison between Silver Fillings vs White Fillings
Amalgam fillings, also known as silver fillings or metal fillings, have been in use for more than 150 years. On the other hand, composite fillings, often referred to as white fillings or tooth-colored fillings, are a relatively recent innovation. They were introduced in the 1960s and have been gaining popularity due to their aesthetic appeal.
We’ll use the following criteria to compare silver fillings vs white fillings:
- Appearance
- Durability and Longevity
- Dental fillingProcedure
- Safety and Health Concerns
- Cost
Appearance
One of the main differences between silver fillings and white fillings is their appearance. As the name suggests, silver fillings, also known as amalgam fillings, are made of a mixture of metals, including mercury, silver, tin, and copper. They have a dark silver color that stands out against the white color of natural teeth.
On the other hand, white fillings, also known as composite fillings, are made of a mixture of plastic (acrylic) resin and powdered glass. The composite material can be color-matched to your natural teeth, making them virtually invisible. However, composite fillings may discolor over time, becoming more noticeable compared to their original color, especially if exposed to staining substances like coffee, tea, or tobacco.
Durability and Longevity
Silver fillings are known for their strength and durability, which is why they have been used in dentistry for over a century. They can withstand heavy chewing forces and last longer than composite resin fillings. On average, silver fillings can last 10-15 years with proper dental care.
White fillings, on the other hand, are not as strong as silver fillings but can still withstand daily chewing forces. They have a shorter lifespan of 5-7 years and require regular dental checkups and good oral hygiene habits. Initially, composite fillings were not as durable as silver amalgam fillings, but advances in dental technology have significantly improved their strength and longevity.
Dental Filling Procedure
Both fillings require one visit to the dentist, although the procedure for each is slightly different. The procedure for placing silver fillings is relatively simple and quick. After the removal of tooth decay, a base or liner is placed in the cavity, followed by the silver filling material. The filling is then shaped and polished to fit your bite.
The procedure for white fillings is a bit more complex. After the decayed part of the tooth is removed, the tooth is prepared with an etching solution. The composite filling material is then placed in the cavity, layer by layer. Each layer is hardened with a special light before the next layer is added. Once all the layers are in place, the composite filling is shaped and polished to match your bite.
An important thing to note in the comparison of silver fillings vs white fillings is the hardening process. Silver fillings (amalgam fillings) begin to harden almost immediately after placement and are usually completely set within 24 hours. This means you should avoid eating hard or crunchy foods on the side of the filling for at least 24 hours after the procedure. In contrast, white fillings (composite) are instantly hardened with the special light used during the procedure, allowing you to eat normally immediately after the appointment.
Safety and Health Concerns
One of the main concerns regarding silver fillings is their mercury content. While the American Dental Association (ADA) has deemed it safe for use, there is still controversy surrounding its potential health risks. Some people believe that mercury from silver fillings can leak into the body over time and cause health problems. However, numerous studies have found no evidence to support this claim.
White fillings are considered a safer alternative as they do not contain mercury. They are made of a composite resin material that is biocompatible and does not pose any known health risks.
Cost of Silver vs White Tooth Fillings
The cost of fillings is also a factor to consider when comparing silver fillings vs white fillings. Silver fillings are generally less expensive than white fillings due to the lower cost of materials and the simpler procedure.
White fillings are typically more expensive than silver fillings because they require a more complex procedure and use higher-quality materials. They also take longer to place, which can increase the overall cost.
Silver vs. White Fillings: Which is Better?
There is no definitive answer to the question of whether silver or white tooth fillings are better. The choice ultimately depends on several factors, including the location of the tooth, personal preference, cost and insurance coverage, and the dentist’s recommendation. Each type of filling has its own benefits and drawbacks that should be carefully considered.
Benefits & Drawbacks of Silver Fillings
Silver fillings, also known as dental amalgam, are a common type of cavity filling. They are known for their durability and can last over 15 years, making them an excellent choice for extensive decay. Amalgam tooth fillings are less expensive and often covered by insurance. However, they are more noticeable due to their silver color and are not ideal for front teeth, where they can be visible when you smile or talk.
Benefits of Silver Fillings:
- Highly durable and long-lasting
- Withstand heavy chewing force
- Suitable for molars and teeth not visible when smiling
- Cost-effective
- Generally covered by insurance
Drawbacks of Silver Fillings:
- Noticeable silver color
- Not suitable for front teeth
- Requires removal of more healthy tooth structure
- Potential for allergic reactions in some patients
Benefits & Drawbacks of White Fillings
White fillings, or resin composites, blend seamlessly with the natural tooth color, making them a popular choice for visible teeth. Although white fillings may not be as long-lasting as silver fillings, they can last 5-7 years with proper care. They are more expensive and might not always be covered by insurance, but the aesthetic benefits often outweigh the costs for many patients.
Benefits of White Fillings:
- Blends with natural tooth color
- Preserves more healthy tooth structure
- Ideal for front and visible teeth
- Provides a strong bond to the natural tooth structure
Drawbacks of White Fillings:
- Less durable than silver fillings
- Discoloration over time
- More expensive
- It may require more frequent replacement
- Not always covered by insurance
Factors Influencing the Choice of Dental Filling
When deciding which type of filling would be best, several factors should be considered:
- Location of the Tooth: White fillings are preferred for front teeth and other visible areas of the oral cavity, while silver fillings are suitable for molars and less visible teeth.
- Cost and Insurance Coverage: Silver fillings are typically more cost-effective and are more likely to be covered by insurance compared to white fillings.
- Aesthetic reasons: Patients who prioritize a natural tooth color and less visible dental work often choose white fillings.
- Dentist’s Recommendation: Experienced dentists and cosmetic dentists can provide valuable advice based on the specific condition of the tooth and the patient’s overall oral health.
Silver Fillings vs White Fillings – Conclusion
In conclusion, both silver and white fillings have their benefits and drawbacks. Silver fillings are more durable and cost-effective, while white fillings offer a more natural appearance and do not contain mercury. Ultimately, the choice between the two types of fillings will depend on your budget, individual preferences, and needs.
If you have any further questions or concerns about silver fillings vs white fillings, it is best to consult an experienced dentist. They will be able to provide you with personalized advice and help you make the best decision for your oral health. Remember, maintaining good oral hygiene habits and regular visits to your dentist are essential for preventing the need for fillings in the first place.
