What are Calcium Deposits on My Teeth?
"Calcium deposits"— known more commonly as tartar or calculus — are a hardened layer of plaque or dental biofilm. Tartar is made of calcium phosphates, among other compounds, and looks white or off-white, so you may hear it called calcium.
Tartar can form anywhere on the tooth surface. It can be especially troublesome when it builds up between the teeth because many people neglect to clean between their teeth with floss, water flossers, or other interdental cleaners. Tartar irritates the gums and serves as a rough surface where disease-causing bacteria can collect, leading to periodontal disease and even inflammation in other parts of your body.
