![]() A somewhat sharp hand instrument may remove the first few millimeters of a calculus deposit, but if continued scaling occurs without resharpening the blade, the instrument will become dull and start to smooth the calculus without removing the remainder of the deposit. One of the main causes of burnished calculus is dull dental instruments. If not removed properly, tartar can lead to larger health concerns. This thorough teeth calculus cleaning process helps keep the patient’s teeth and gums healthy. Calculus is more difficult to remove, so when patients go to their dentist’s office, the dental hygienist will use special tools to remove any tartar. When plaque stays on the teeth too long, it can harden and become tartar.įortunately, removing plaque is relatively easy with regular brushing and flossing, preventing gum disease and permanent tooth decay. Plaque contains bacteria that can harm tooth enamel and cause cavities. Tooth calculus formation occurs when the bacteria in the mouth mixes with proteins and food residue to form a sticky film on the teeth and gum line known as dental plaque. Unlike burnished calculus, regular calculus - also referred to as tartar - is rough and porous.

This article discusses the causes of burnished calculus and the complications of removing the deposits, along with some burnished calculus removal tips and suggestions for preventing tooth calculus buildup. Although the surface of the tooth with burnished calculus may appear smooth and pristine, the deeper layers of its calculus are still full of pathogenic biofilm. Removing burnished calculus is imperative because even the smallest amount of burnished calculus can cause an ulcerated lesion in the overlying tissue, leading to a chronic state of inflammation and potential infection until the calculus is removed. This makes it difficult to remove the deposit because the cutting edge of the dental instrument easily slips on the deposit’s smooth surface. Burnished calculus is smooth because the outermost layer has been removed.
