Metal-Free Fillings


For a long time, metal crowns and metal fillings were acceptable treatments for some dental conditions. They were used for treating the teeth at the back. Findings talking about the potential toxicity of mercury in the crowns and fillings encouraged people to develop and look for healthier alternatives. We at the San Anselmo Family Dentistry are serious about your oral health. We offer metal-free fillings and crowns for your dental work while still improving your natural smile and health.


There are many advantages that come with choosing fillings for your teeth that are free of any metal, some of which are listed below:

  • Eliminate toxins: Findings pointed to slow release of toxins from metal fillings. Mercury vapors after escaping from the fillings can reach other parts of the body – heart, lungs, stomach, liver, intestines, etc. The onset of the symptoms and effects of mercury poisoning can be slow taking over 20 years. Toxic mercury can cause other issues such as dizziness, depression, neurological damage, migraines, ulcers and more. Although the debate is open, claiming that the levels of mercury are too low to cause any serious damage, it is better to protect the overall health of your body.
  • Less sensitivity: Metal fillings can be more sensitive to cold and hot causing toothache.
  • Stronger bond: Metal-free fillings bond directly to the surface of the tooth ensuring a strong bond. Old metal fillings had the risk of causing some movement or shift.
  • Better look: The metal is seen in the metal fillings showing dark lines that are not aesthetically pleasing. Metal-free fillings are made to match the shade of the rest of your teeth giving it a natural look that you can flaunt with confidence.


Accumulation of plaque and tartar along with bacteria cause tooth decay. Cavities are formed causing damage to the enamel and the inner layers of the teeth. At the far end of the severity scale, root canal treatment would be needed to restore the teeth. But at the early stages, fillings from a variety of materials can be used to cover up the holes created by the cavities.


Metal-free fillings are called composite resins. The material comes close to the natural color of the teeth, which adds to the appeal. Your dentist will first remove the decayed part of the tooth that is to be repaired. A gel and bonding agent is used to prepare the teeth before filling it with the composite resin to ensure that it bonds firmly to the teeth. The resin is then filled, layer-by-layer, and molded to the required shape. Special light is used to harden it, after which it is trimmed and polished.
