Natural Smiles with Metal-Free Dentistry

By Gerald Regni, DMD on March 28, 2018

Only a few years ago, metal-free dentistry was an unknown concept. Most fillings were made of a silver-mercury alloy, while inlays, crowns, and bridges were composed of cast gold. These were the best materials available for their time, but decades of research and technological advances have made possible more attractive—and possibly safer—alternatives. Dr. Gerald Regni and Dr. Adil Salik of Dr. Gerald Regni & Associates routinely employ the latest technology in their Philadelphia, PA, dental office to practice virtually metal-free dentistry. In doing this, they also use natural and holistic methods that focus on total body health. As evidenced by the success stories and reviews from satisfied patients, they have the experience, skill, and training to perform procedures while prioritizing your health.

Metal Dental Restorations Have Drawbacks

The use of metals for dental restorations can be traced back thousands of years. They are strong, inexpensive, readily available, and easy to work with. They are still used today, but they can have certain drawbacks.

  • Appearance – Since metals do not have the same appearance as natural teeth, they are not aesthetically pleasing.
  • Tendency to Corrode – Some metals can corrode and cause an unpleasant taste or bad breath.
  • Heat Conductivity – Metals transmit heat and cold much faster than natural teeth, which often contributes to tooth sensitivity.
  • Galvanic Current – Dissimilar metals in the mouth can create an electrical current. This can cause a painful sensation known as galvanic shock.
  • Mercury Toxicity – Silver-mercury alloy filling materials are known to release low levels of toxic mercury vapor, which accumulates in the body's vital organs.

There Are Nonmetallic Alternatives

  • Composite Fillings are tooth-colored plastic materials. They are safe and effective and can be used as an alternative to silver-mercury amalgam material. In addition to being virtually invisible in the mouth, they bond directly to enamel, making them very retentive.
  • Porcelain Veneers are thin sheets of porcelain fabricated in the dental laboratory and bonded to visible surfaces of teeth. They effectively cover teeth surfaces that are worn or broken down or marred by stains or old fillings.
  • Inlays and Onlays are conservative restorations that restore teeth, which have been broken down by decay or old fillings. Though traditionally made of cast gold, they can now be fabricated in the dental laboratory from safe and biocompatible ceramic materials.
  • Dental Crowns are caps that completely enclose broken down natural teeth to increase their strength and resistance. They can also serve as false teeth attached to dental implants. Like inlays and onlays, crowns were traditionally made of cast metal but can now be fabricated from tooth-colored ceramic materials.
  • Dental Bridges fill spaces caused by missing teeth. They can be attached to natural teeth or implant abutments. These too were conventionally made of cast metal but can now be fabricated—either all or in part—using nonmetallic, tooth-colored materials.
