Tooth decay at gum line treatment cost
The cost of treating gum-line decay depends on lesion depth, tooth location, moisture control, material, and whether the pulp is involved.
The short answer
Gum-line decay is a carious lesion near the enamel-cementum junction or an exposed root surface.

What is the direct answer?
What does this question mean?
The dentist removes softened tooth structure when needed and may restore it with glass ionomer or resin composite; deep disease may need pulp treatment and a crown.
What can you do next?
Brush gently along the margin, clean between teeth, limit frequent sugar or acid, and do not scrape the lesion.
When should you seek dental care?
Arrange prompt care for a visible notch, sensitivity, food trapping, or rough margin; swelling or spontaneous pain may signal deeper disease.
What should you ask the dentist?
Ask how deep the lesion is, which material fits the site, and what the proposed treatment includes.
