Which activity is commonly performed during dental hygiene appointments?

During dental hygiene appointments, professional cleaning is a commonly performed activity. This involves a thorough cleaning of the teeth using specialized instruments to remove plaque, tartar, and stains from the surface of the teeth. Professional cleaning is essential for maintaining oral health, as it helps prevent gum disease and cavities by ensuring that the teeth are clean and free from harmful bacteria.

In contrast, tooth extractions, cavity fillings, and orthodontic adjustments are procedures that typically fall outside the scope of a dental hygiene appointment. Extractions and fillings are dental treatments that usually require a dentist's intervention, while orthodontic adjustments are performed by orthodontists to modify braces or other orthodontic appliances. Therefore, professional cleaning is the main focus during dental hygiene visits, emphasizing preventive care and the maintenance of oral health.
