THE GMO TOOTH MICROBE THAT IS SUPPOSED TO PREVENT CAVITIES

Summary from the TLDR newsletter

Lumina is a one-time treatment that can present cavities. It can be applied either at home or by a dentist. The treatment, which can be pre-ordered for $250 (before taxes and shipping fees), is expected to be released by mid-June. Marketed as a cosmetic product, the treatment has yet to successfully move through human clinical trials, leading to safety and ethical concerns.
