Can You Replace Old Fillings with White Ones?

Many patients who have older metal (amalgam) fillings now wonder, "Can you replace old fillings with white ones?" The simple answer is yes—and it’s a popular choice for both cosmetic and health reasons.

Why Replace Old Fillings?

Older fillings, especially those made from silver amalgam, were once the standard for restoring decayed teeth. While effective, they come with several drawbacks:

• Aesthetic Concerns: Metal fillings are very noticeable, especially when laughing or talking.

• Cracking and Leakage: Over time, metal expands and contracts with temperature changes, potentially causing cracks in the surrounding tooth structure.

• Mercury Content: Amalgam fillings contain mercury, a toxic metal. Though the levels are low and considered safe by many dental associations, some patients prefer to eliminate any potential risk.

• Wear and Tear: Like any dental material, fillings wear down over time and may need replacement to prevent further tooth damage.

Benefits of White Fillings

White fillings in Docklands, also known as composite fillings, are made of a tooth-colored resin material that blends seamlessly with your natural teeth. They offer several benefits:

• Improved Aesthetics: Composite fillings match your natural tooth color, making them virtually invisible.

• Stronger Bonding: They chemically bond to your tooth structure, which helps support and strengthen the remaining tooth.

• Less Drilling: Removing less natural tooth structure is often possible with composite materials, preserving more of your healthy tooth.

• Mercury-Free: White fillings contain no metals or mercury, appealing to those seeking more holistic dental care.

The Replacement Process: What to Expect

Replacing old fillings with white ones is a straightforward procedure that can typically be done in a single dental visit, depending on how many fillings need to be replaced. Here’s what the process usually involves:

1. Consultation and Examination: Your dentist in Docklands will assess the condition of your existing fillings and determine if they can be safely removed and replaced.

2. Removal of Old Filling: The old amalgam filling is carefully removed. This may involve protective measures to prevent inhalation of mercury particles.

3. Tooth Preparation: The tooth is cleaned and prepared for the new composite material.

4. Filling Application: The composite resin is applied in layers and cured with a special light.

5. Shaping and Polishing: The dentist shapes and polishes the filling to match the contours of your natural tooth.

Is It Safe to Remove Amalgam Fillings?

Yes, but it should be done by a qualified dentist using appropriate safety protocols. Some patients opt for what's known as SMART (Safe Mercury Amalgam Removal Technique), which includes:

• High-volume suction

• Dental dam barriers

• Mercury-absorbing masks and filters

These steps help ensure that the procedure is safe for both the patient and dental professionals.

When Should You Replace Fillings?

Not all fillings need to be replaced right away. However, you should consider replacement if:

• The filling is cracked, leaking, or worn out

• You experience tooth sensitivity or discomfort

• You’re concerned about the appearance of your smile

• You want to eliminate mercury from your dental work

A routine dental exam is the best way to determine whether your old fillings need replacement.
