Dental calculus cleaning is the removal of mineralized plaque and tartar that accumulate on the teeth and between the teeth and gums, performed by a skilled dentist. 

During a dental check-up, your dentist will typically perform the following steps:

1. Examination: Your dentist will first examine your teeth and gums to assess the presence of plaque and tartar buildup.
2. Scaling: If plaque and tartar buildup is identified, your dentist will use either ultrasonic instruments or hand tools to gently remove the dental calculus from the surfaces of your teeth and along the gumline.
3. Polishing:Following scaling, your teeth may be polished using a special instrument to make them cleaner and smoother. Fluoride may also be applied to strengthen your tooth enamel and provide additional protection against cavities.
4. Recommendations: Finally, your dentist may provide recommendations for improving your oral hygiene at home, including regular brushing, flossing, and the use of interdental brushes. They may also offer advice on diet and lifestyle factors that can affect your oral health.

Dental calculus cleaning is typically a painless procedure, although some individuals with sensitivity or gum issues may experience some discomfort. This process is essential for maintaining healthy teeth and gums and supports good oral hygiene when combined with regular dental check-ups.
