The Benefits of Metal-Free Tooth Fillings

Tooth Fillings San Diego

In the 1990s, following an exposé on 60 Minutes, public awareness of the hazards of mercury in amalgam fillings increased significantly.  Not coincidentally, around that same time, the use of metal-free fillings became more desirable. Many people even began to replace their old metal fillings with new ones made from resin composite.  

If you’re considering replacing your metal fillings with metal-free fillings, or if you’re just looking for some information on why that might be a good idea, you’ve come to the right place. At Soft Touch Dental, Dr. Fakhimi specializes in white fillings and composites.  Take a look below at some of the benefits of metal-free tooth fillings:


Metal fillings often contain some level of mercury, a toxic material that has been linked to a number of diseases and medical conditions. That mercury can sometimes leak from cracked fillings and require immediate treatment. Reducing mercury exposure overall is good for the health of people and the environment.


Both resin composite and porcelain fillings can be matched to the color of your teeth, so they look natural (and you don’t have to cover your mouth to hide unsightly metal fillings when you laugh). That’s much more aesthetically pleasing than the huge piece of silver or other metal broadcasting to everyone that you’ve had a cavity.

Less drilling required

We want to be as efficient with your time as possible. One of the benefits we’ve seen with metal-free fillings is that they can be applied more quickly. Composite fillings, for example, involve less drilling than the amalgam fillings of yesterday, largely because less of the original tooth needs to be removed in order to place the filling. Less time in the chair for you means we can restore your smile and get you back to your life as quickly as possible.

Durable and resistant

Ceramics are naturally resistant to abrasion as well as staining from coffee and other foods and drinks. Resin is more susceptible to staining but gains strength and resilience when combined with other materials such as glass ionomer. Ceramics have also been shown to last up to 15 years, meaning you don’t need to worry about them being repaired or replaced for quite some time.


Unlike resin and ceramic, metal conducts heat and cold. Also, your teeth expand and contract slightly when exposed to hot or cold food and drink, but metal does not. This means that eating or drinking anything above or below a “normal” temperature can cause at best discomfort and at worst severe pain in your teeth if you have metal fillings. Non-metal filling options are simply more comfortable, allowing you to live your life without wincing whenever you drink hot coffee or a cold milkshake.
