Before and After Replace Amalgams with Composite Resins
Posted on 6/15/2026 by Davis Dental Practice |
 Let's talk about tooth fillings! For many years, silver-colored fillings, also known as amalgams, were the go-to choice for dentists. They were strong and lasted a long time. But today, many people are choosing tooth-colored fillings, also called composite resins. This article will explore what happens when you switch from amalgams to composite fillings, and why you might consider making the change.
What are Amalgam Fillings?
Amalgam fillings are made from a mix of metals, including silver, mercury, tin, and copper. They've been used for over a century because they're durable and can withstand the forces of chewing. However, their dark color makes them stand out in your mouth.
What are Composite Fillings?
Composite fillings are made from a mixture of plastic and glass. They're designed to match the natural color of your teeth, making them much less noticeable. Dentists bond the composite material directly to the tooth, which can help strengthen the tooth structure.
The Replacement Process
Replacing amalgam fillings with composite fillings usually involves a few steps. First, your dentist will examine your teeth and take X-rays to assess the condition of your existing fillings and the surrounding tooth structure. If everything looks good, the dentist will numb the area around the tooth to ensure you're comfortable.
Next, the dentist will carefully remove the old amalgam filling. They'll use special tools to break it up and suction it away, making sure not to damage the healthy parts of your tooth. Once the amalgam is removed, the dentist will clean and prepare the tooth surface for the composite filling.
The dentist will then apply the composite material in layers, using a special light to harden each layer. This process ensures a strong and durable bond between the filling and your tooth. Finally, the dentist will shape and polish the filling to match the natural contours of your tooth, making it look and feel natural.
Benefits of Switching to Composite Fillings
There are several reasons why people choose to replace their amalgam fillings with composite fillings.
| • |
Aesthetics: Composite fillings blend seamlessly with your natural teeth, making them virtually invisible. This can significantly improve the appearance of your smile. |
| • |
Tooth Structure: Composite fillings bond directly to the tooth, which can help strengthen the remaining tooth structure. Amalgam fillings, on the other hand, don't bond to the tooth and can sometimes require the removal of more tooth structure to create space for the filling. |
| • |
Mercury Concerns: Some people are concerned about the small amount of mercury in amalgam fillings. While studies have shown that amalgam fillings are generally safe, some individuals prefer to avoid mercury altogether and opt for composite fillings. |
| • |
Reduced Sensitivity: Composite fillings are less likely to cause sensitivity to hot and cold temperatures compared to amalgam fillings. This is because composite material doesn't conduct heat and cold as readily as metal. |
What to Expect After the Replacement
After getting composite fillings, you might experience some mild sensitivity to hot and cold for a few days. This is usually temporary and can be managed with over-the-counter pain relievers. It's important to maintain good oral hygiene by brushing and flossing regularly to keep your new fillings clean and prevent decay.
Switching from amalgam to composite fillings can be a great way to improve the appearance and health of your smile. Talk to your dentist to see if composite fillings are the right choice for you.
