Tooth cavity filling cost
The cost of a cavity filling depends on the tooth, decay depth, filling material, and whether diagnosis or additional treatment is needed.
The short answer
A cavity filling cost is determined by the tooth involved, the size and depth of decay, the material selected, and any examination or treatment needed around the filling. A dentist reaches that estimate after examining the tooth and, when needed, taking an X-ray.

What is the direct answer?
What does this question mean?
A filling repairs a cavity after the dentist removes infected or softened enamel and dentin. The final treatment may be a small direct composite restoration, a larger restoration, or another procedure if decay has reached the pulp or weakened the tooth.
What can you do next?
Arrange an examination and ask for a written plan that identifies the tooth, the decay extent, the proposed material, and each included step. Do not judge estimates by material name alone because isolation, bonding, bite adjustment, X-rays, and follow-up needs can change the treatment involved.
When should you seek dental care?
Book dental care promptly for toothache, sensitivity that lingers after hot or cold, food trapping, a broken tooth, or a visible dark or soft area. Urgent assessment is appropriate for facial swelling, fever, difficulty swallowing, or difficulty breathing.
What should you ask the dentist?
Ask how deep the cavity is, whether an X-ray is needed, which restoration suits the tooth and bite, and what happens if the decay is close to the pulp. Also ask what the quoted fee includes and whether a crown, root canal, or replacement would be considered if the tooth cannot be restored with a filling.
Frequently asked questions
Does a deeper cavity change the treatment?
Yes. Decay near the pulp may require pulp protection, root canal treatment, or a different restoration rather than a simple filling.
Which filling material should I choose?
The choice depends on location, moisture control, cavity size, bite forces, appearance, and the dentist's assessment of the tooth.
