So...I will be at the half way mark with rads tomorrow and I wanted to pass anlong an idea I had that has been working great with my floride trays. Mt dentist said to lay a very small beed of floride inside the trays and it would "smush" all over my teath just right. I've found it difficult to get the right amount in there and evenly without rubbing it around the trays with my finger. Last week I asked a dental hygenist friend of mine to get me a couple if the big plastic syringes they give you to fulsh out the holes where wisdom teath used to be when you have them out (big bent plastic syringes with no neeedle). Oddly enough I had asked her for them so I could seel some grout in my new shower without getting any on the tile itself. I have since found that I can squirt some of the floride into the back of the syringe (pull plunger out) and push out a perfect beed into the trays without making a mess or using my finger. I also put a small piece ot tape over the end of the syringe so the floride doesn't dry up over night. I believe they are either very cheap or even free. I hope this can help some folks. It's made it A LOT easier for me. Will Zinn
