Do you have a family history of heart disease or periodontal disease? You may want to consider the MYPerioPath saliva DNA test. You simply swish with a sterile saline solution in your mouth and spit into a tube. The sample is then sent to OralDNA Labs, where testing is performed. The same bacteria that can cause periodontal disease are the same pathogens that can be responsible for heart disease. The mouth is the window to your health, keep it happy and healthy!
