This Scientist was ready to investigate if tea and coffee
stains teeth. She supplemented egg shells for teeth and explored how long it would take to stain the egg shells.
Sadly for the tea and coffee drinkers out there, Aiko discovered that they both stain your teeth. She investigated that tea is even worse than coffee because of the higher tannin content. The only good news is that Aiko recommends good dental practice to help reduce staining. Aiko enjoyed working in this project and did an excellent job. Now go and brush your teeth you coffee and tea drinkers.
