Why You Should Replace Metal Fillings

According to the Centers for Disease Control and Prevention (CDC), more than 90% of adults have had at least one cavity, and about 25% currently have untreated cavities. Although silver (amalgam) fillings were traditionally used to address these issues, recent studies have highlighted potential health risks associated with them. To learn why replacing silver fillings with tooth-colored options is beneficial and how they offer a safer, more attractive alternative, read on.

What Are Dental Fillings Made From?

Amalgam fillings are made from a blend of metals including silver, copper, and tin. They have been commonly used to repair teeth affected by decay and are known for their durability under biting and chewing forces. In contrast, modern dental fillings are created from composite resin, which combines dental-grade plastic with glass and ceramic particles.

Both amalgam and composite fillings effectively restore the strength and function of damaged teeth. Even so, many dental and health professionals now recommend composite fillings as a superior option to silver amalgam.

Disadvantages of Metal Fillings

Metal fillings come with several drawbacks that make dentists suggest getting composite ones instead, including:

• Tooth sensitivity and enamel damage –Amalgam fillings don’t stick well to teeth and can expand and contract with temperature changes. This can cause tooth sensitivity and small cracks in the enamel, weakening the teeth over time.
• Highly noticeable –Amalgam fillings are made of metal and can be quite noticeable, which may make you feel self-conscious about your smile.
• Mercury content –The FDA says amalgam fillings are safe, but some studies suggest that people with eight or more metal fillings might have higher mercury levels in their blood. Mercury can be toxic and may cause neurological issues, skin rashes, and other health problems.

4 Benefits of Tooth-Colored Fillings

Luckily, tooth-colored composite fillings offer several advantages over metal fillings, including:

• Seal out bacteria –Tooth-colored fillings form a tight bond with the tooth enamel, creating a barrier that prevents harmful bacteria from entering the tooth.
• Enamel preservation –Composite fillings are adaptable and chemically bond with the surrounding enamel, which helps strengthen the tooth and ensures a secure fit. Additionally, placing tooth-colored fillings typically requires little to no removal of healthy enamel.
• Lessen tooth sensitivity – Tooth-colored fillings are made without any metal, making them a great choice for patients with metal allergies or sensitivities. They also stay stable and do not expand or contract with changes in temperature.
• Seamless integration –Composite resin fillings are carefully color-matched to your natural teeth, blending effortlessly with your smile and making them nearly invisible.
