Are Dental Crowns and Fillings Safe? Understanding Non-Toxic Materials in Holistic Dentistry

When it comes to dental restorations like crowns and fillings, safety is a top concern for many patients. In recent years, there has been growing awareness of the potential health risks associated with certain dental materials, particularly amalgam mercury fillings, fluoride, other heavy metals, plastics, BPA, and other carcinogens. Fortunately, safer alternatives exist, and modern dentistry offers non-toxic solutions for fillings and crowns. At Pure Smiles Center for Advanced Dentistry, we offer safe alternative materials for crowns and fillings and SMART amalgam filling removal to

protect our patients’ health.

The Problem with Amalgam Fillings

Amalgam fillings, also known as silver fillings, have been used for over a century due to their durability and affordability. However, they contain approximately 70% mercury—a toxic heavy metal that can release harmful vapors.

Research has shown that mercury exposure from dental amalgam can contribute to a variety of health concerns, particularly for sensitive populations such as pregnant women, children, and individuals with compromised immune systems. These concerns may include neurological issues, kidney problems, and allergic reactions. The World Health Organization (WHO) and other health organizations have recognized these potential risks, leading to a global shift from mercury-containing dental materials.

The Problem with PBAs & Plastics

Many dental materials, including sealants and composite resins, contain plastic-based compounds, some of which may release BPA—a chemical linked in some studies to hormonal disruption, developmental issues in children, and possible increased cancer risk. Even minimal exposure can be significant, especially in young or vulnerable patients.

Fluoride, the Hidden Threat

Fluoride, commonly used in toothpaste, mouth rinses, and professional treatments to prevent tooth decay, has long been under scrutiny by holistic dentists. Excessive fluoride intake, especially in children, can lead to dental fluorosis (white or brown spots on teeth) and may be associated with neurological concerns. Some researchers and public health advocates question the necessity of widespread fluoride use because the risks often outweigh the benefits in areas where fluoride is already present in the water supply. Increasing public awareness has fueled a demand for more natural, biocompatible alternatives like those used by Dr. Shahbazi.

Safe Alternatives for Fillings and Crowns

With advancements in dental materials, patients now have safer and more aesthetically pleasing options for fillings and crowns.

Safe and effective filling alternatives include:

1. Composite Resin Fillings – Made from a blend of resin and ceramic, composite fillings are durable, tooth-colored, and free from toxic metals.
2. Ceramic Fillings (Porcelain Inlays/Onlays): Porcelain fillings are strong, long-lasting, and completely free of toxins. Our ceramic fillings are available the same day.

Safe and effective alternatives for crowns, all of which are available the same day, include:

1. Porcelain Crowns – Known for their strength and natural appearance, porcelain crowns are metal-free and biocompatible.
2. Zirconia Crowns – Made from a durable ceramic material, zirconia crowns are both safe and resistant to wear.
3. Lithium Disilicate Crowns – This advanced ceramic material offers strength and a natural look.

These alternatives not only provide a non-toxic solution but also enhance the appearance of your smile without compromising health.

The SMART Method: Safe Removal of Amalgam Fillings

Dr. Shahbazi and her dental care team use the SMART (Safe Mercury Amalgam Removal Technique) method for patients who already have amalgam fillings and wish to have them removed safely. The International Academy of Oral Medicine & Toxicology (IAOMT) endorsed the SMART protocol. It involves a series of protective measures to minimize mercury exposure during removal. These steps include using a rubber dam to prevent mercury particles from entering the mouth and high-volume air filtration and suction to remove mercury vapors. We also provide an external oxygen supply to avoid inhaling toxic fumes. We also use copious amounts of water and chunk removal of the amalgam to reduce mercury exposure.

Although amalgam fillings pose potential risks due to their mercury content, we offer safe and effective alternatives such as composite, ceramic, and zirconia restorations. Additionally, the SMART method provides a secure way to remove existing amalgam fillings while minimizing mercury exposure and giving us the opportunity to replace them with better, safer alternatives.
