Scaling (Dental Calculus Removal) Information
According to NHIA regulations, individuals aged 13 and above can apply for health insurance-covered full-mouth scaling once every six months; pregnant women and certain high-risk groups (e.g., diabetes, dialysis, malignant tumors, cerebrovascular diseases) can receive it every three months. Scaling is a periodontal maintenance procedure to remove calculus and plaque, performed by a dentist using ultrasonic or hand instruments. The following is neutral public information.
How is dental calculus formed?
Dental plaque is a bacterial film that adheres to tooth surfaces. If not removed by brushing and flossing, it gradually mineralizes and calcifies into hard dental calculus, which cannot be removed by brushing alone and requires professional removal by a dentist using instruments. Calculus buildup is associated with gingivitis and periodontal disease; regular removal helps maintain periodontal health.
General process of scaling
Scaling is a periodontal maintenance procedure to remove calculus and plaque. Common methods include:
- Ultrasonic scalers are often used to vibrate and remove calculus, accompanied by water spray.
- Hand instruments may be used to remove fine deposits or calculus at the gumline as needed.
- Polishing of tooth surfaces may be performed to reduce plaque reattachment.
Common temporary effects after scaling
Some individuals may experience the following temporary conditions after scaling, which usually improve gradually. If persistent or uncomfortable, consult your dentist:
- Teeth may become temporarily sensitive to hot and cold.
- Spaces previously filled with calculus may become visible, creating a sense of gaps.
- If gums were inflamed, slight bleeding may occur during cleaning.
Frequently Asked Questions
How often should scaling be done?
According to health insurance regulations, individuals aged 13 and above can apply for covered full-mouth scaling once every six months. Actual recommended frequency varies by individual periodontal condition and should be evaluated by a dentist.
Is scaling covered by health insurance?
According to NHIA regulations, individuals aged 13 and above can apply for covered full-mouth scaling once every six months. Pregnant women and certain high-risk groups (e.g., diabetes, dialysis, malignant tumors, cerebrovascular diseases) can receive it every three months. Subject to NHIA and clinic explanations.
What is the difference between scaling and deep scaling (root planing)?
Regular scaling removes calculus above the gum line; deep scaling (root planing) treats calculus below the gum line for periodontal disease, with different scope and cost. Whether needed is evaluated by a dentist based on periodontal condition.
Does scaling make teeth sensitive?
Some patients may experience temporary tooth sensitivity after scaling, which usually resolves on its own. If there are special conditions, inform the dentist during the visit. This site only compiles public information, not medical advice.
What should be noted after scaling?
Generally, maintain normal oral hygiene (brushing, flossing). If there are specific precautions, follow the dentist's instructions. This site only compiles public information.
Who may need more frequent visits than usual?
Patients with periodontal disease, pregnant women, or those with specific oral conditions may be advised by the dentist to have different recall and scaling frequencies. Actual frequency is based on individual treatment plans. This site compiles public information, not medical advice.
Does dental scaling make gaps between teeth larger or teeth looser?
This is a common misconception. Scaling removes plaque and tartar; it does not 'loosen' teeth. If gaps seem larger or teeth feel looser after scaling, it is usually because tartar was filling the gaps or inflamed gums were swollen, masking pre-existing issues. After removal, the underlying bone loss and gum recession caused by periodontal disease become apparent. In other words, scaling reveals existing periodontal conditions, not causes them. If teeth feel significantly loose, seek a dentist's evaluation for possible periodontal treatment. This site only compiles public information and is not medical advice.
