Redser,

I had both conventional radiation and brachytherapy, and from what I've read here, the post-treatment dental regimen is about the same in either case. It's good that you're being diligent about brushing and flossing and keeping your mouth as moist as possible.

Dry mouth problems can set you up for dental issues because your mouth isn't routinely getting the full range of enzymes in normal saliva that help to keep your teeth and gums healthy. Many of us have been using Biotene mouthwash/gel/spray/toothpaste products, which are specifically designed to deal with these problems. (I'm not sure whether they're available in Europe.) Also, I've been using Salagen (generic name: oral pilocarpine) on a regular basis to boost my saliva production -- I know this works better for some people than others. Another medication for this purpose is Evoxac.

It's also important to get some extra fluoride protection going forward. This can be done with "trays" that are fitted to your teeth and are typically used to apply fluoride gel for 5-10 minutes at a time. Alternatively, you can get a prescription fluoride toothpaste that you brush onto your teeth (I try to do this once a day -- an electric toothbrush is especially good for this).

You probably will also need periodic teeth cleanings more frequently than you did before. It's pretty standard after radiation to need cleanings every 2-3 months because plaque can build up faster.

If you don't have a dentist who's trained to look for post-radiation problems, I'd suggest that you try to find one (as well as a periodontist you can see from time to time to check on the condition of your gums).
