What is the primary purpose of a dental scaler?

The primary purpose of a dental scaler is to remove plaque and tartar from the surfaces of teeth. Dental scalers are specialized instruments designed to effectively clean teeth, particularly in areas where buildup is prevalent, such as along the gum line and in between teeth. By removing these deposits, scalers help prevent gum disease and cavities by maintaining oral health and hygiene.

Plaque is a soft, sticky film that forms on teeth, while tartar, or calculus, is hardened plaque that has mineralized and can only be removed through professional cleaning. Using a dental scaler makes it possible to thoroughly clean these deposits, thus allowing for a healthier mouth and reducing the risk of dental issues.

The other options, such as polishing teeth, applying fluoride treatments, and checking for cavities, are important activities in dental care but do not reflect the primary function of a dental scaler. Polishing is typically performed after scaling to smooth the tooth surface and enhance appearance. Fluoride treatments are preventive measures against decay, and checking for cavities involves diagnostic techniques, rather than cleaning.
