If your fillings are still working well, there may be no need to remove them. An emergency dentist can help you decide what’s best for your oral health.

April 3, 2025Amalgam fillings, or silver fillings, used to be really useful. They contain a mix of metals, including mercury, silver, tin, and copper. These fillings last a long time and withstand years of chewing pressure. However, many people are thinking about replacing amalgam fillings. Some worry about mercury exposure, while others dislike the way silver fillings look. Let Kirkland Dental Excellence put your mind at ease.
Do Amalgam Fillings Need to Be Replaced?
Replacing amalgam fillings isn’t always necessary. If they are intact, free of cracks, and still sealing the tooth, you can keep them. But in some cases, replacing them makes sense.
Many people worry about the mercury in these fillings. Health experts, including the ADA and FDA, say these levels are safe for most people. However, pregnant women, young children, and those with certain health conditions may be more sensitive to mercury exposure. So, they are in more need of an amalgam filling replacement. For those seeking a safer and more natural-looking alternative, a dental bonding can restore teeth without metal.
Even without mercury concerns, we have some amalgam fillings side effects. They expand and contract while the temperature changes, which can crack teeth over time. They may also wear down or loosen, which allows bacteria to cause decay.
Reasons to Replace Amalgam Fillings
There are several good reasons for replacing amalgam fillings:
- Silver fillings stand out, especially on the front teeth. Many people prefer tooth-colored options that blend in naturally.
- These fillings can put pressure on the surrounding tooth and cause cracks or fractures over time.
- If this filling becomes loose or worn down, bacteria can enter the space and cause new cavities.
- Metal fillings conduct heat and cold, which can make teeth more sensitive to temperature changes.
- Though rare, some people develop allergic reactions to the metals in amalgam fillings.
Replacing Amalgam Fillings with Composite
One of the most popular options for replacing amalgam fillings is composite resin. Composite fillings are built from a blend of plastic and fine glass particles. They match your natural teeth color, which makes them nearly invisible.
The Process of Replacing Amalgam with Composite
To replace amalgam fillings with composite:
- Your dentist examines the old filling and checks for cracks, decay, or leaks. Then, they use local anesthesia to numb the area.
- Your dentist carefully drills out the old filling. They take care to remove as little tooth structure as possible. Then, they thoroughly clean the tooth to remove bacteria and prepare it.
- Your dentist layers the composite material into the cavity and shapes it to fit the tooth. Then, they use a special light to harden the composite material.
- Finally, your dentist smooths and polishes the filling to ensure a perfect bite.
Benefits of Composite Fillings
They:
- Match the color of your teeth.
- Require less drilling than amalgam.
- Create a strong, secure seal.
- Do not expand or contract while the temperature changes.
