Those old gumline cavities are practically diagnostic for Sjogrens. My dentist was the first one to mention possible sjogrens to me. Saliva has protective enzymes in it which help protect the enamel on our teeth. And especially the saliva that comes from the inner cheek saliva glands.
Here's what I do (it's from JoAnnRDH): I get my teeth cleaned every 6 months. I use an electric toothbrush (she recommended Sonicare FlexCare), waterpik, and floss. I use the PBF version of Biotene toothpaste and mouthwash (the latter often throughout the day and night). I also had the dentist make some of those tooth-whitening trays which I fill with either Prevident (Rx F toothpaste, yucky tasting) or MI Paste (a remineralizing paste) and soak my teeth in it for about 1/2 hour each week.
It finally paid off. My last visit was squeaky clean.
It's a lot of work and expensive, but not nearly as expensive as repeated fillings followed by extractions.
I think the fluoride and remineralizing pastes could help your teeth, maybe even reverse some of the damage? It's good to get on it quickly. Teeth are pretty vulnerable in Sjs.
