Question: 1 / 400

What is the nature of the abrasive action of chalk in dental polishing?

Aggressive and deep

Mild and surface-level

The abrasive action of chalk in dental polishing is mild and surface-level, making it suitable for use in oral hygiene. Chalk is composed primarily of calcium carbonate, which provides a gentle abrasive quality that can effectively remove plaque, stains, and debris from tooth surfaces without causing damage to the enamel. This property is particularly important in a dental context, as overly aggressive abrasives could lead to enamel wear and increase the risk of tooth sensitivity and decay.

The mild nature of chalk allows dental professionals to polish teeth effectively while preserving the integrity of the tooth structure. By focusing on surface-level cleaning, chalk helps to maintain a bright smile while minimizing potential harm to the enamel surface. This characteristic makes it an ideal material for coronal polishing procedures aimed at enhancing the appearance of teeth and promoting overall dental health.
