Skin Rashes
Among some individuals, the use of fluoride toothpaste may cause or aggravate perioral dermatitis (a rosacea-like skin rash around the mouth). (McCaffery 2003; Mellette 1983, 1976). The condition usually appears in women between the ages of 20 and 50. Where fluoride toothpaste is the cause of the condition, significant improvement in symptoms will be experienced within a few weeks of using a non-fluoridated toothpaste. In addition to dermatitis, fluoride toothpaste may also causestomatitis (i.e., mouth ulcers, “canker sores”). (Brun 2004; Douglas 1957).
