All About Metal-Free Fillings

In the last two decades, dentistry has come a long way. Earlier, tooth decay and cavities were fixed with metal fillings. But with the advancements in dental technology, metal fillings are increasingly being replaced with composite or tooth-colored fillings. These metal-free fillings have many distinct benefits, including aesthetic appeal, versatility and are entirely safe for the health.

What Are the Disadvantages of Metal Fillings?

Metal-free fillings allow you to avoid the harmful effects of the amalgam materials that were previously used to treat cavities. There are several adverse effects of amalgam, which is composed of silver and mercury. Though amalgam is hard and durable, it looks nothing like teeth and can negatively impact the appearance of your smile. Also, as you age, these fillings absorb moisture and expand, chipping the tooth structure. In addition, metal fillings need a significant portion of the tooth structure to be reshaped to secure them.  Lastly, metal fillings are vulnerable to temperature changes and can weaken the teeth, causing bacterial infections and eventual tooth decay.

What Are Metal-Free Fillings?

Composite fillings have become the most widely preferred solution to fix cavities. They do not cause any problems usually associated with the metal fillings and they offer several benefits, including:

  • Aesthetic Enhancement

Composite fillings are fabricated from resin and contain either plastic or glass. They are designed to match the color of the natural teeth and blend in seamlessly. The composite fillings have a discreet appearance and offer great aesthetic appeal. 

  • Versatility

Composite fillings are also highly versatile and durable. They offer the same toughness and wear resistance as metal fillings but also provide enhanced cosmetic appeal. Composite fillings can even be used to repair chips, cracks, and fractures or worn down as well as decaying teeth.

  • Non-Toxic

The tooth-colored filling material is composed of composite resins, making it a safer alternative to metal fillings. They do not trigger allergic reactions and are entirely safe for patients.

  • Minimal Tooth Structure Reduction

Amalgam fillings require a significant amount of enamel removal, causing teeth to become weak and prone to pain. On the other hand, composite fillings can be placed with the least amount of tooth reduction possible. These fillings provide additional support to decayed teeth, allowing for preserving your remaining teeth's structural integrity.

  • Resistant to Temperature Change

As the amalgam fillings are made of metal, they expand and contract when exposed to heat or cold, leading to tooth fractures and breakage. On the other hand, the insulating properties of composite fillings shield them from hot and cold foods, making them resistant to temperature changes.

  • Durable

With the latest technology, the function and quality of composite fillings have improved, and they can now last for years.
