Hello! I know that dental care/fluoride treatment has been discussed a lot on this forum, but I have kind of a general question I'm hoping someone could help me with.
The dental oncologist prescribed me to just use the Gel-Kam fluoride daily (in dental trays) for life. I am approaching 2 years post treatment, and so far I haven't had any real dental issues, aside from a couple of small cavities.
However, I noticed the amount of fluoride in the treatment is actually very low (on par with the amount in my toothpaste), and I have seen other people on the forum discuss that Gel-Kam isn't enough. I also get pretty bad dry mouth, especially at night.
My question is this: if I haven't had any issues so far, should I assume that it's working for me and not worry about changing to prescription, or is the tooth decay a very gradual thing that could already be happening now, and I need to switch ASAP?
My dentist said my teeth look good and when I asked him about switching, he said it wasn't necessary. However, he is not a dental oncologist so I figured I would consult with my team of experts here before I push the issue further

Thank you!
