Dental decay treatment
Dental decay treatment ranges from fluoride care for early mineral loss to fillings, root canal treatment, or removal for deeper disease.
The short answer
Dental decay is treated according to how far it has progressed: early mineral loss may be managed with fluoride and plaque control, while a cavity may need a filling, and pulp involvement may require root canal treatment or removal.

What is the direct answer?
What does this question mean?
Decay is a disease process in which acids produced by plaque bacteria remove minerals from enamel and dentine. If the tooth surface breaks down, the cavity can deepen toward the pulp, the living tissue containing nerves and blood vessels.
What can you do next?
Brush twice daily with fluoride toothpaste, clean between teeth, limit frequent sugary or acidic exposures, and attend examinations so early lesions can be assessed. A dentist may use visual inspection, drying, bitewing radiographs, or other tests to determine the depth.
When should you seek dental care?
Seek care for pain, sensitivity that lingers, a visible hole, food trapping, a dark or soft area, swelling, or a broken tooth. Facial swelling, fever, or difficulty swallowing needs urgent assessment.
What should you ask the dentist?
Ask how deep the lesion is and whether it is active. Ask whether fluoride management, a filling, a larger restoration, root canal treatment, or removal is needed, and how the tooth can be protected afterward.
