Calculus
Calculus, also known as tartar, is a hardened deposit that can form on the surfaces of teeth. It is a common dental condition that occurs when plaque, a sticky film of bacteria and food particles, hardens and mineralizes over time. Calculus can accumulate both above the gumline, known as supragingival calculus, and below the gumline, known as subgingival calculus.
Supragingival Calculus
Supragingival calculus is the type of calculus that is visible on the tooth surface, typically along the gumline. This type of calculus is usually yellow or brown in color and can have a rough or grainy texture. Supragingival calculus is formed when plaque interacts with certain minerals in the saliva, such as calcium and phosphate, causing it to harden and become calcified.
The presence of supragingival calculus can lead to several dental issues. It can irritate the gums, causing them to become red, swollen, and prone to bleeding, a condition known as gingivitis. Gingivitis is the earliest stage of periodontal (gum) disease and, if left untreated, can progress to more advanced stages of the disease, such as periodontitis.
Supragingival calculus can also make it more difficult to effectively clean the teeth, as it can provide a rough surface for additional plaque to accumulate. This can further contribute to the development of gum disease and tooth decay.
Subgingival Calculus
Subgingival calculus is the type of calculus that forms below the gumline, in the space between the tooth and the gum (known as the periodontal pocket). This type of calculus is often more difficult to detect and remove, as it is hidden from view.
Subgingival calculus is generally more problematic than supragingival calculus, as it can lead to more severe gum disease. The presence of subgingival calculus can cause the gums to become inflamed and the periodontal pockets to deepen, which can ultimately result in the loss of supporting bone and tooth loss.
Causes of Calculus Formation
Calculus formation is influenced by several factors, including diet, oral hygiene habits, and the natural composition of an individual's saliva. Individuals with higher levels of certain minerals in their saliva, such as calcium and phosphate, are more prone to developing calculus. Additionally, certain medications and medical conditions, such as dry mouth (xerostomia), can contribute to the formation of calculus.
Removal and Prevention of Calculus
Calculus can only be removed through professional dental cleaning procedures, such as scaling and root planing, performed by a dentist or dental hygienist. During these procedures, special instruments are used to carefully scrape away the hardened deposits from the tooth surfaces, both above and below the gumline.
In addition to professional cleaning, maintaining good oral hygiene at home is essential for preventing the buildup of calculus. This includes brushing teeth twice a day, flossing daily, and using an antimicrobial mouthwash. Regular dental check-ups and cleanings are also important for the early detection and removal of calculus before it can cause more serious dental problems.
Calculus: Conclusion
Calculus is a common dental condition that can have significant consequences if left untreated. Understanding the formation, types, and impact of calculus, as well as the importance of professional and home-based oral hygiene, is crucial for maintaining good dental health. By working closely with a dentist or dental hygienist, individuals can effectively manage and prevent the buildup of calculus, reducing the risk of gum disease and other dental problems.
