Amalgam Fillings

What are Amalgam Fillings?

Amalgam fillings, otherwise known as silver fillings, are a dental restorative material used to repair teeth that have decayed. Made from an alloy of mercury combined with other metals, they include silver, mercury, tin, and copper. Being very durable, resistant, and less expensive, amalgam has been used in dentistry for more than 150 years.

How Do They Work?

Cavity Preparation: The dentist removes the decayed portion of the tooth and prepares the cavity for the filling. This may involve shaping the cavity to ensure the amalgam can be securely placed.

Placement of Amalgam: Mix the amalgam material and pack it into the cavity. The dentist shapes it back to the natural contours of the tooth.

Hardening: Amalgam tooth fillings set rapidly—usually within a few minutes. The patient is then able to use the filled tooth almost immediately.

Advantages of Amalgam Fillings:

Strength: Because amalgam fillings are so strong, they bear the forces of chewing well, due to which they are used majorly for restoring the molars, where the pressure is maximum.

Longevity: Such fillings have a potential to last as long as 10-15 years or more if cared for properly; often, they outlast other kinds of fillings.

Cost-Effective: These are quite low-cost fillings when compared with other filling materials, be it composite or ceramic.

Less Moisture-Sensitive: Amalgam is placed in an environment slightly moist during one's placement, which is quite easier to work with, sometimes.

Considerations:

Aesthetics: The color of amalgam is dark, so these types of fillings are quite visible, especially in the visual appearance of the mouth.

Mercury Content: It has amalgam, which increases concerns over its safety. However, studies have returned that mercury in dental amalgam is stable and does not pose any harm to health. The regulatory bodies take amalgam fillings to be safe for most people.

Tooth Structure: Some healthy tooth structure must be removed for placing the amalgam fillings, as enough space is required to hold the filling in place.

Temperature Sensitivity: Amalgam is sensitive to temperature change; over time, it can cause a filling to expand or contract, which may lead to cracks or fractures on the tooth.

Who Might Need Amalgam Fillings?

Amalgam fillings are recommend for patients who have cavities, especially in back teeth where more force and durability is required. It also works perfectly for people who wish to have a more economically friendly treatment.

Procedure and After Care:

Procedure: An amalgam filling is typically placed in one visit. Patients may experience sensitivity after the procedure, but it usually subsides after a few days.

Aftercare: Good oral hygiene, therefore the habit of brushing and flossing regularly is of prime importance for the survival of the amalgam filling. Regular dental check-ups are also necessary.

Alternatives to Amalgam Fillings

Composite Fillings: Filled with resin that is tooth-colored, these types of fillings are more attractive. They can be less strong than amalgam, however.

Ceramic Fillings: The dental ceramic filling is very strong and tooth-colored. On the other hand, it can turn out to be quite expensive.

Gold Fillings: These are durable and biocompatible fillings. On the other hand, they are pretty expensive and take more than one visit for their placement.

Conclusion:

They provide an excellent method for restoring an original tooth that is affected by decay: amalgam fillings are durable, strong, and relatively inexpensive. Although some issues have been raised regarding esthetics and mercury content, it is still one of the most common and most reliable materials used in dentistry today.
