<<Disclaimer: Verify this information before applying it to your situation.>> Thanks to everyone for their suggestions and help in finding previous relevant posts. I will include only new information in this summary. Dentsply (800-989-8825, www.dentsply.com) - I called them and was told that their entire NUPRO line of products is GF. I asked about wheat, oats, barley & rye and the representative said they are very aware of gluten and get several phone calls a day about it. This product line includes: prophy paste for cleaning/polishing, topical fluoride, and a tooth whitening system. Reliance Orthodontics Products (800-323-4348, www.relianceorthodontics.com) - I called them since they carry an unflavored pumice (for cleaning/polishing) that is used at my daughter's dentist office. The company would not discuss the ingredients on the phone but were willing to fax the ingredient list to her dentist. There are only a few simple ingredients which all appear to be GF. The product is called "1st and Final" and her dentist said it is also used in orthodontics. ----------- Suggestions by other listmates: ProDentec (800-228-5595, www.prodentec.com) - carries a line of GF dental products Sultan Dental Products (201-894-5500, 800-238-6739, www.sultandental.com) - Customer Service says the following are GF: Topex Pina Colada Prophy Paste (the only flavor that is) and Topex Topical Anestetic Gel (numbing agent). Note: their Flouride Foam and other prophy pastes DO contain gluten I am a dental hygienist who is also a celiac. To my knowledge Nupro Prophy paste is gluten free. The Helio seal sealant is also gluten free. I'm not sure about the fluoride, but if your child is taking fluoride vitamins and brushes daily with a fluoride toothpaste, doesn't get excessive decay, you can probably forgo the fluoride treatment. ----------- My daughter's dentist is very supportive and even studied celiac disease (briefly) in dental school. If anyone is looking for a pediatric dentist in Metrowest Boston, send me a line. Cindy in Massachusetts
