The removal of both subgingival (below the gum line) and supragingival (above the gum line) calculus is primarily achieved through mechanical methods. This approach typically involves the use of hand instruments, such as scalers and curettes, as well as ultrasonic scalers.

Mechanical methods are effective because they rely on physical force to disrupt and remove the hardened deposits of plaque and calculus that can form on and around the teeth. The scaling action helps to clean both the visible surfaces of teeth and the areas that are not directly visible to the eye, extending beneath the gum tissue where subgingival calculus can accumulate.

While there are other methods like chemical dissolution, regular brushing, and laser treatment, these alternatives may not comprehensively address the calculus that has formed in both areas efficiently. Mechanical removal is considered a standard practice for achieving thorough dental cleaning.
