It can cause damage to your teeth. Radioactive Iodine caused me to have a very dry mouth. For over a year I couldn't make very much saliva at all. That has led to erosion of enamel (without saliva to protect it) and now I just had to get my first filling ever not due to cavities, but due to holes in my tooth's enamel exposing nerves from losing enamel due to dry mouth caused by radioactive iodine treatment. It's been a week since the filling and starting grinding my teeth again (I feel stressed) and the same tooth has crumbled a little (IT HURTS!) and is soft due to radiation. I have brushed regularly, flossed, swished forever trying to prevent this. If your mouth is even slightly feeling dry (I didn't notice it that bad at first, I was just really thirsty. The thirst was because my mouth was drying out.) Avoid alcohol and alcohol based mouthwashes. Use something like Rincinol or Aloclair. I've at least done damage control down to one tooth affected. Best wishes!
