Welcome to our forum luckytiger. Many Lupies have Sjogren's symptoms, and drymouth can cause halitosis. If you have dry mouth (like I do) make sure that your mouth rinse doesn't contain alcohol which drys the mouth even more. I also use Biotene toothpaste and floss daily. I have also been looking on Amazon which has quite a few dry mouth products and I'm going to order Thera Breath lozenges.
Another thing to consider is some of the meds we take cause bad breath and I don't think there's anything we can do about
If are organs are causing this we could have them removed, wait a couple of weeks to see if our problem is solved, and then have the doc put them back. Of course we would be on ice for those couple of weeks.
