New study tests simple ways to erase chalky white spots on teeth without drilling

NCT ID NCT07704983

First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time

Summary

Dental fluorosis can leave chalky white spots on front teeth, affecting appearance even when the enamel is intact. This trial compares two gentle treatments—resin infiltration and enamel microabrasion followed by a calcium-phosphate paste—for masking those spots. Researchers measure color matching and spot size from photos taken before, right after, and up to six months later. The goal is to find which approach works better and lasts longer.

What this could lead to
If successful, this could offer a simple, effective way to improve the appearance of fluorosis-related white spots on front teeth without drilling or filling.
What could go wrong
This is a small, short-term study (42 people, 6 months). Results may not apply to everyone, and the effects might fade over time.
