Alpaca you're pretty tough for a Kiwi mate!

I had a tooth decay problem before my other problems, my dentist told me to rub a thin smear of Sensodyne toothpaste on my teeth, spit but don't rinse, and leave it on when I go to bed. Worked ok, but I couldn't handle it when my mouth went crazy during treatment. I would try it and if it doesn't bother you sleeping, its a cheap treatment.

You don't mention mouthwashes? You must be pretty trained and experienced on the bicarb mouth washes by now yeah?

Hey if you need some inspiration I had a picture of a brave girl installed at your house. I put it above the bathroom sink.
