WHY GUM CARE
Why is Gum Care
So Important?
Gums are the foundation of your teeth.
Healthy foundation means healthy teeth.
Cavity Prevention
Healthy gums protect tooth roots, reducing the risk of cavities.
Longer Tooth Life
Strong gums keep teeth stable, allowing them to last longer.
Avoid Implants
Gum care prevents tooth loss, helping you avoid expensive implants.
Cost Savings
Prevention is cheaper than cure. Regular care saves significant costs.
Gum Care = Tooth Preservation = Health + Savings
Prevention is the best treatment.

gum treatment is a good one.

COMPARISON
Isn't Brushing and Scaling
Enough?
Both are extremely important,
but perfect care is difficult with them alone.
Brushing
Maintain surface cleanliness
Cannot remove tartar (calculus)
Does not reach below the gum line
Scaling
Remove supragingival tartar
Prevention and minor treatment
Limitations in deep areas
Gum Treatment
Treatment deep below the gum line
Smoothing roots with root planing
Treatment for advanced disease

Frequently Asked Questions
Isn't scaling enough?
Scaling is the first step in tartar removal. However, if gum disease has progressed, precise treatment using special equipment to remove bacteria deep in the gums is necessary. Getting gum treatment every 6 months will help preserve your natural teeth longer.
I heard gum treatment is painful. Will it be okay?
Don't worry. Yonsei Ona Dental has a multi-step pain relief system. Many patients are surprised saying "I didn't know dental treatment could be this comfortable." We do our best to ensure treatment without discomfort.
How often should I get treatment?
Basic scaling once a year (covered by insurance), gum treatment every 6 months is ideal. In severe gum condition cases, 3-month intervals are more effective. Regular care can help you use your natural teeth for life without needing implants.
How does insurance coverage work?
Scaling is covered by health insurance once a year. If gum treatment is needed, insurance can be applied and treatment is done in stages. We'll explain detailed coverage scope during consultation.
Why do other clinics avoid gum treatment?
Honestly speaking, implants are more profitable than gum treatment. Also, if extraction becomes necessary after gum treatment, it can lead to patient complaints, so many clinics avoid it. However, Yonsei Ona Dental prioritizes natural tooth preservation and boasts high success rates with our collaborative care system.
