Saliva deposits: Dental tooth plaque is formed from deposits from your saliva. Some people have more such deposits than other people. It is a factor of your saliva. You can do proper toothbrushing to prevent a build-up of plaque deposits on your teeth. You can also use listerine plaque preventive mouthwash, which helps reduce the build-up with proper toothbrushing. If you get a lot of plaque go to the dentist.

Arterial Plaque: Atherosclerosis, also known as “hardening of the arteries”, occurs when areas of the artery wall thicken in response to either increased modifiable (high LDL particle levels, smoking or high blood pressure )and non-modifiable (genetics, age, gender) risk factors. Over time, areas of focal thickening may grow into a larger lesion called a “plaque" that can limit blood flow through the vessel.
