The appearance of calculus loss usually means clinically that the calculus has reached a very serious condition, because early calculus is relatively very small and adheres firmly to the surface of our teeth, or within the gingival sulcus. This condition is common in patients with very poor oral hygiene and thick calculus. This kind of patients must be recommended to go to a professional dentist as soon as possible for calculus cleaning, which is what we usually call scaling. Scaling is a method of shattering large pieces of calculus by means of ultrasonic vibrations and rinsing out the broken calculus by applying sterile water. Scaling is also professionally known as supragingival scaling, and is the best way to deal with calculus at this time. Long-term calculus deposits can cause poor periodontal hygiene, which can lead to gingivitis, periodontitis, swelling and bleeding of the gums, and eventually gum recession and resorption of the alveolar bone, causing loosening and loss of teeth.
