    <dc:description>DATASET CORRECTION — Version 2, 13 July 2026

Version 1 of this dataset included:

per-state braces cost estimates;
per-state veneers cost estimates;
a “Composite Cost Index.”

An internal audit found that these series were not based on independently observed data. They had been derived from the dental implant series using fixed multipliers.

These series have therefore been retracted and removed.

Validated data

The dental implant cost series remains valid and is based on independently collected data. It has been externally validated against the ASQ360° / CareCredit Average Procedural Cost Study, with a Spearman correlation of 0.945 across 51 jurisdictions.

Index revision

The former “Composite Cost Index” has been renamed:

Restorative Cost Index

It has also been rebased as follows:

100 = observed national average dental implant cost of $4,507

Required action

Please discard all copies of Version 1 and use only the corrected Version 2 dataset.

Restorative Cost Index: 10.5281/zenodo.20531728
Procedural cost dataset: 10.5281/zenodo.20819436
City-level dataset: 10.5281/zenodo.20819438

Independent 2026 dataset of average dental prices across all 50 U.S. states and the District of Columbia: single dental implant (low/avg/high), per-tooth veneer, full-course braces, a composite Cost Index (100 = national average), the state cost-of-living index, and an affordability score. Key finding: dental prices track cost of living at Pearson r = 0.835; cheapest Alabama ($3,759), priciest California ($5,733). This is market and pricing research, not clinical advice.
