"Dental disease - I have Sjogren's Disease as well as RA and other auto immune diseases. I recently attended my dentist who I see every 6 months. On this visit she concentrated on informing me of the risk I take because of my dry mouth. She has prescribed Ducophat toothpaste which has a very hihe concentration of fluoride 5000. This will help stop the damage done by my diseases and therefor prolong the health of my teeth. This toothpaste is only available from dentist on prescription. I have looked on the web to source it, and certainly cheaper than I was charged. What I found was that my dentist was by far the cheapest £8.50 per 21ml tube. I hope some of you are able to get some benefit from this info."
