When is it necessary to remove calculus from teeth?

The necessity of removing calculus from teeth prior to performing coronal polishing is crucial for several reasons. Calculus, or tartar, is hardened plaque that adheres to the surface of the teeth and can create a rough texture. If not removed before coronal polishing, the polishing will be less effective, as the abrasive materials used during the polishing process may not adequately reach the surfaces of the teeth beneath the calculus. Additionally, leaving calculus in place can lead to gum irritation and complications with periodontal health, ultimately undermining the goals of coronal polishing, which is to enhance the smoothness and appearance of the teeth.

In contrast, while it is important to remove calculus before orthodontic treatment and during routine check-ups, these contexts do not specifically align with the timing of coronal polishing. Similarly, removing calculus after brushing is not standard practice, as the purpose of brushing is to prevent plaque buildup; any calculus present should ideally be addressed beforehand to ensure optimal oral health and hygiene.
