Dental Demonstration

This week I’m teaching my four-year olds about dental hygiene. I’d like to have some of those chew tablets that turn your teeth red, showing the plaque, if you didn’t brush your teeth and tongue correctly. Does anyone know where I could get some and how I can ask for them in Chinese? I’m in Kaohsiung.

I’d also like to get a bottle of rubbing alcohol and Debrox ear cleaning solution, if anyone knows where I can get those. I’ve already been to four Watson’s and a couple of smaller mall pharmacies with no luck.
