All dental amalgam restorations, also commonly referred to as silver fillings, contain approximately 50% mercury1. Unsafe mercury removal can be harmful to the patient, dental professionals and the environment. Dr Nguyen is an accredited member of the IAOMT and one of the few certified dental providers who specializes in safe mercury-amalgam removal using the strict SMART protocol, which consists of:

  1. Charcoal and chlorella to rinse and swallow before and after the treatment.
  2. A dental dam is placed to isolate the tooth being worked on to avoid any contact with soft tissues or swallowing particles.
  3. Protective garments are placed on the patient including surgical gown, hat, and face and neck shield.
  4. Oxygen is delivered to the patient via a nasal canula during the mercury removal process.
  5. A separate oral aerosol vacuum, with is placed 2 to 4 inches from the patient’s mouth to mitigate mercury exposure. Slow and high volume suction is also used at all times.
  6. An amalgam separator is used to collect all mercury particles from being released into the environment.
