How this works

This free scan uses teewai's CIEDE2000 colorimetry, the science of measuring color precisely using the same formula dental spectrophotometers use. No AI, no server. For the full analysis (visible staining and discoloration estimates, per-tooth shade breakdown, personalized plan), create a free account after scanning.

For the most accurate shade match, place a white index card next to your teeth as a color reference. teewai uses it to calibrate for your lighting.

Free scans are a quick estimate. Signed in scans are more accurate because they calibrate against your full scan history. Log in for the most accurate results.
