Why Resin Composite Fillings Should Replace Amalgam Fillings

When it comes to dental fillings, there are two main options available: amalgam and resin composite. Amalgam is the traditional method of filling cavities, but the newest technology in dentistry is the use of resin composites. Resin composite fillings are made from a combination of plastic and glass particles, and they offer several advantages over traditional amalgam fillings. Let’s take a look at why resin composite should replace amalgam fillings. 

Durability 

One of the key advantages that resin composite fillings have over traditional amalgam fillings is their durability. Unlike metal-based amalgams, which can expand and contract with temperature changes, resin composites remain stable no matter what kind of conditions they are exposed to. This means that the risk of cracking or chipping is much lower with resin composites than it is with metal-based materials. Additionally, because they are so durable, they require less frequent replacement than their metal-based counterparts. 

Appearance 

Another advantage that resin composite has over traditional amalgam is its appearance. While metal-based amalgams tend to be dark grey — not exactly an ideal aesthetic for your teeth — resin composites can be customised to match the exact shade of your natural teeth. This makes them virtually unnoticeable when you smile or speak, giving you peace of mind that your teeth look as natural as possible after a filling procedure has been performed. 

Safety 

Finally, one big advantage that makes resin composite preferable to amalgam is safety. Metal-based amalgams contain mercury — a toxic substance that can be hazardous to your health if it leaches out into your system from the filling material itself or from abrasion caused by chewing or grinding your teeth together. With resin composites, you don’t have this problem; all materials used are non-toxic and completely safe for both short-term and long-term use inside the mouth.  

Conclusion 

The bottom line is that there are many advantages to using resin composites instead of traditional metal-based amalgams for dental fillings — increased durability, greater aesthetic appeal, and improved safety all make them an excellent choice for anyone looking for an effective filling option. If you're considering having a cavity filled shortly, talk to your dentist about using a high-quality resin composite instead of an amalgam filling; you won't regret it!

What are the benefits of resin composite fillings?

Resin composite fillings offer several advantages over amalgam fillings, including aesthetic appeal as they are tooth-coloured and match the natural shade of your teeth. They also bond to the tooth structure, creating a stronger seal and reducing the potential for decay under and around the filling. Additionally, less tooth structure is removed when preparing for resin composite fillings than with amalgam ones.

Are resin composite fillings more expensive than amalgam ones?

Generally speaking, resin composite fillings cost more than amalgam ones due to their higher quality material and longer procedure time. However, they may last significantly longer than amalgam fillings and require fewer replacements, which can help reduce long-term costs associated with dental care. 

Are resin composite fillings safe to use?

 Yes, resin composite fillings are considered safe for use in adults and children alike. They are recommended by many healthcare professionals as a better alternative to amalgam fillings due to their lower risk of toxicity and greater aesthetic appeal.
