Things are going great during my winter break. Now that I have completed 3 whole weeks of using Invisalign it has become second nature. The Invisalign dieting is working pretty well too =). Instead of seeing something that I want to eat and just putting in my mouth, I have to make a conscious decisions whether it is worth the effort to remove my aligners and clean my teeth afterwards, just for a little snack. I also have gotten used to just drinking water all day, even when i have my aligners off. It is healthier for my body as well as my teeth.
As far as cleaning, I continue to brush my teeth and aligners after each time I eat. Some morning I use the Listerine pre-brush rinse and I think it works pretty well. They look a lot clearer and smell minty fresh after I soak them in the solution for a while. The active ingredient is hydrogen peroxide, so you could just use that, which is much cheaper.
Dr. Kammer informed me that the CCD does have the sonic/ultrasonic cleaners as well as the retainer brite tabs. They are resonably priced. When you go to the clinic ask about it if you are interested.
