Do UV toothbrush sanitizers actually work?
Reviewer consensus
The evidence is mixed. Across r/microbiology and r/askdentists threads we read, commenters repeatedly flag that consumer UV-C toothbrush cases advertise '99.9% germ kill' without published study data, and an r/AmazonVine thread cautioned that some units generate ozone as a byproduct. Treat UV sanitizing as a nice-to-have, not a proven hygiene upgrade over simply letting the brush air-dry.
