Safe Mercury Amalgam Removal Technique (SMART)

All dental amalgam restorations contain approximately 50% mercury, and reports and research are consistent that these fillings emit mercury vapors.

Scientific research demonstrates that dental mercury amalgam exposes dental professionals, dental staff, dental patients, and/or fetuses to releases of mercury vapor, mercury-containing particulate, and/or other forms of mercury contamination. Furthermore, mercury vapor is known to be released from dental mercury amalgam fillings at higher rates during brushing, cleaning, clenching of teeth, chewing, etc., and mercury is also known to be released during the placement, replacement, and removal of dental mercury amalgam fillings. Utilizing the available scientific evidence, the IAOMT has developed extensive safety recommendations for removal of existing dental mercury amalgam fillings, including detailed protective measures that are to be utilized for the procedure. The IAOMT’s recommendations build upon traditional safe amalgam removal techniques such as the use of masks, water irrigation, and high volume suction by supplementing these conventional strategies with a number of additional protective measures, the need for which have only recently been identified in scientific research.

Holistic/Biological Approach

Studies by Clarkson (1998) and the World Health Organization found that one silver amalgam filling could release anywhere between 3-18 m gm/day of mercury.

I recently moved into the area and needed to find a dentist I felt I could trust. After reading about Medplex I knew that they were a good fit for me given their holistic approach to dentistry. After my first visit, I was BEYOND satisfied with the care and service I was given! Dr. Castellini is a very relaxed and most importantly HONEST practitioner. I am looking forward to giving even greater care to my oral health with the Medplex Dental team behind my back :)

From the moment you check in at the front desk, you can feel the kindness. Maite is excellent and always takes the time to explain paperwork and always makes me feel at ease. She also has a great sense of humor. Nelly, the hygienist has the most gentle smile and also has a gentle touch, so does Susanna the dental assistant. Robert Castellini , the dentist, never makes me feel rushed and has a great personality. I will never go anywhere else as I’ve found my home.

This dentist is amazing! My experience at the office is always pleasant. They’ve been nothing but kind and helpful. I had to get a lot of fillings done and it was all pain free, which I definitely wasn’t expecting. If you need work done on your teeth definitely check this place out.
