What causes the body to produce dental tartar, and how does tartar control toothpaste reduce the amount of tartar buildup on the teeth?

Tarter is caused by a bacteria that resides in your mouth, plaque. When plaque builds up it creates a biofilm. If you leave this biofilm on your teeth it will eventually harden which is commonly known as tartar. Toothpaste uses a combination of “cleaning” chemicals that interact with the biofilm to dispel it, however, biofilm are hard to get rid of which is why we use toothbrushes to physically remove it.
