Invention: Light Curing Dental Adhesives and Restoratives
3M is also one of the world’s largest dental companies! Using nano-ceramics and light-curing resins, 3M has developed new tooth-colored fillings. The new fillings still show up on dentists’ X-rays, but they prevent the tinsel-teeth effect of metal fillings. And the fast-curing materials make your trips to the dentist quicker.
