Question: What is Calculus?
Answer: Calculus, also known as tartar, is the hardened residue that forms on your teeth when plaque is not removed. Plaque can be removed by brushing twice a day and flossing daily. If tartar is allowed to remain on the teeth and below the gumline, it can lead to chronic infection and inflammation. The only way to remove tartar is to have your teeth professionally cleaned at your dental office.More Dental Care Q&A
