How clean are YOUR teeth?
Using disclosing tablets we were able to find out how clean our teeth were? We had to crunch a tablet and swirl it around our mouth. We then had to sup some water to rinse our mouth and spit out the tablet.
Some of us did not like this investigation, but we all took part and tried hard to keep the tablet in our mouth.
Using mirrors we could see the plaque on our teeth. Our teeth were red and so were our lips. We looked like we were wearing red lipstick!
