Special metal and toxin diagnostics
Current measurement
All metal alloys in the oral cavity corrode over time. The resulting low-level electrical current can be measured using special, patented carbon electrodes. Carbon is used because it has no electrical current of its own.

Chewing gum saliva test
A chewing gum saliva test can be use to determine the extent of abrasion of heavy metal sources in the mouth that takes place during everyday chewing. For this test, saliva is collected over a 10-minute period during which the patient chews chewing gum.

DMSA chelation test
The oral DMSA chelation test detects heavy metal deposits. After oral administration of DMSA the patient's urine and stool samples are examined for heavy metals commonly used in dentistry.
If the patient does not tolerate DMSA or DMPS, we can use a hair analysis to determine mercury contamination which is not so accurate because it does not show long term intoxication

Biopsies
Oral tissue biopsies show the concentration of metals absorbed in the tissue. These biopsies are taken under local anesthesia. Hair mineral analysis is an available but not accurate alternative for patients with multiple allergies and intolerances that cannot undergo a surgery . Formaldehyde detection Nearly twenty years ago, we became one of the first practices to demonstrate that formaldehyde, a carcinogen/allergenic, can be detected in the bone and dental root. Until that point, it had been assumed that formic acid and methyl alcohol were the only detectable decay products. In order to detect formaldehyde, we send sterile test tubes containing chronically inflamed bone parts to an environmental laboratory, where the samples are then tested for formaldehyde.
