“Arterial plaque is a deposit of fat, cholesterol, calcium and scar tissue that develops in the artery wall. Plaque in the mouth is a bacterial film that builds up on teeth. While the two types of plaque are very different, patients with gum disease do seem to have nearly twice the risk of also having heart disease.”

Your decision to cut out sugars should help a lot. Fish oil is good for you and is also anti inflammatory.
