I used my trays every night through treatment and for almost a year. My saliva returned to about 75-80% of what it was so I started to use them less. My teeth are fine, but when the oral surgeon heard I was down to using them about once a week and brushing with flouride a few times a week, he really encouraged me to use the trays 3-4 times a week as a preventative measure. I'm taking his advice and started to use the trays daily.

I get my teeth cleaned every 4 months. I find that my teeth and tongue stain quite a bit (yay for drinking red wine and coffee). It's probably due to the decrease in saliva and also in the type of saliva. I use a tongue scraper daily and sometimes use some biotene gel with it.

As far as brushing my teeth...while I was home during treatment, I brushed my teeth probably 8 times a day. One thing I found extremely helpful is going to someone who speacilized in oral cancers. The oral surgeon I see is "out of network," and expensive, but he has given me great advice. He also tends to do more of a physical exam than the oncolgist or ENT. He checks for fibrosis in my neck and pokes around my mouth a lot.
