Dental Amalgam
Dental amalgam is a filling material that has been used by dentists for over 150 years. A mixture of metals that typically includes silver, copper and tin, dental amalgam fillings (commonly referred to as “silver fillings”) also contain mercury, which has raised safety concerns among patients from time to time.
In response to those concerns, the U.S. Food and Drug Administration (FDA), American Dental Association (ADA) and other organizations have conducted numerous studies over several decades and have repeatedly found that the small amount of mercury released during placement and removal of amalgam fillings does not cause adverse health effects.
Amalgam fillings remain a safe, cost-effective and durable choice when it comes to the restoration of decayed teeth.

Frequently Asked Questions about Amalgam Fillings
Why is amalgam still used to fill teeth when composite materials are available?
While composite (or “tooth colored”) fillings are more durable than ever thanks to advancements in technology, there are still many cases where amalgam fillings perform better (and longer). This is often the case with teeth that are naturally subjected to extensive chewing force, such as molars. Mercury is an important part of the amalgam mixture as it contains unique elements that allow it to be manipulated with ease during placement and then harden quickly after. In addition to the benefits of longevity, amalgam fillings are also more affordable than composites.
What concerns are there with mercury and its effects on the body?
Mercury is a naturally occurring metal and one that we are exposed to in small amounts through water, air and food throughout our lives. Excessive exposure to mercury can negatively affect the brain and kidneys – however, it is important to understand that amalgam fillings do not cause dangerous levels of mercury exposure. Numerous scientific studies and thoughtful research have led the FDA to stand behind its position: amalgam fillings are a safe and effective restoration method for patients over 6 years of age.
What is the ADA’s position regarding the use of silver amalgam fillings?
A thorough summary of evidence ranging from 2004-2010 led the ADA to reaffirm its position that amalgam is a valuable and safe choice for patients.
When is it appropriate to use composite fillings?
Composite fillings are typically made of a resin and glass mixture, tinted to the color of your tooth, and commonly referred to as “white” or “tooth-colored” fillings. They serve an important purpose for teeth that are visible when smiling, providing an aesthetic benefit not afforded by silver fillings. While resin composite fillings undoubtedly look better than amalgam ones, they are generally considered to be less durable, and therefore may not be ideal for teeth that are subject to extreme chewing and biting forces. It is worth noting, however, that composite materials continue to benefit from technological advancements, contributing to enhanced durability. The ADA supports composite materials in small or mid-size fillings on teeth that are exposed to moderate pressure from chewing, and acknowledges that they are a good choice for a more natural-looking filling.
The bottom line?
The ADA Council on Scientific Affairs has concluded that both amalgam and composite materials are considered safe and effective for tooth restoration.

Patient Review by Tamara’e T
Okay I'm not exactly sure where to begin ..I'm going to try to keep it as short as possible and straight to the point. I have very very bad anxiety and I stress myself to the point I can't stop crying and just have a very bad time being relaxed. I think my fear was caused from unpleasant dental visits as a child and throughout adulthood. I've been having a really bad tooth ache for a while. The pain would come and go but it finally got to the point that it was unbearable. I actually felt like the pain was in my left ear. A bit discouraged with finding a dentist during this covid-19 stuff going on I hopped on yelp and proceeded to look for dentist that had experience with treating clients with anxiety. Dr. Pena had very good reviews which prompt me to call. I reached out to Dr.Pena and she was really nice over the phone, she ordered me a prescription to help with pain and set me up for a next day appointment to be seen. Today was my first time visiting Dr.Pena and I can honestly say this was the best experience I've ever had in my life with visiting the dentist. She explained everything to me step by step. She and her assistant ( I don't remember her name we're so nice and attentive and caring) she numbed me very very good. The best numbing I've ever had. I've had experiences of not being numbed enough and feeling terrible pain during procedures. She knows exactly what she's doing and completed my root canal quickly. I felt pretty embarrassed at how bad I was crying during the procedure. I always humiliate myself,lmao and SMH. It's hard to explain but in that moment I actually feel like I'm dying... Thank goodness there weren't any children in the office. This experience has really changed how I feel about visiting the dentist. Even though I cried my heart out, I feel really proud of myself. Well anyways , I have to go back in a month or so to get the root canal completed. I already feel much better and I know what to expect now. I am so grateful to this wonderful professional and nice Dentist. I look forward to taking better care of my teeth and visiting the office in the future. I highly recommend Dr.Pena. P.S the office is clean, there is ample parking as well!

Patient Review by Brenda A
I cannot speak highly enough about this dental office. I called on Thanksgiving weekend with severe tooth pain. I left a message and within minutes I received a text from Dr Pena. She was able to call in antibiotics and see me the following Monday at 7am. The office staff and everyone has been so responsive and amazing. PS I hate having all dental work done this is one of the first places where I feel comfortable!! They are amazing!

Absolutely wonderful first visit. I have not been to the dentist in a very, very long time. I was prepared for the worst. Gail was incredibly pleasant and real, which I very much appreciated. Dr. Pena was also very gentle and communicated everything perfectly. I had a full understanding of what was needed and what my future visits would be like. Billing was painless and I had a clear understanding of the present and future costs, allowing me to plan accordingly. Very pleasant visit. Thank you!
