<<Disclaimer: Verify this information before applying it to your situation.>> Hi Everyone! I called Procter & Gamble (800-543-7270) and they said that Scope Mouthwash and all of the Crest Toothpastes are GF! I was using Aquafresh Whitening, which SmithKline Beecham (800-245-1040) says contains trace amounts of gluten. Regards, Julie
