Many dental products contain dangerously high levels of fluoride. For years, manufacturers and dentists failed to warn consumers about the risks from ingesting these products. Although the FDA (USA) now requires manufacturers to warn consumers that fluoride products are poisonous when swallowed, manufacturers and dentists are still using these products in ways that expose consumers and patients to potentially toxic levels of fluoride.
The vast majority of toothpastes now contain fluoride.
Although research suggests adult-strength fluoride toothpaste (1,100-1,450 ppm F) can reduce tooth decay, this potential benefit comes with the risk of disfigured teeth.
Use of fluoride toothpaste during childhood is a major risk factor for dental fluorosis, particularly for children who brush before the age of three and who live in areas with fluoridated water.
Children who swallow fluoride toothpaste can reach fluoride levels in their blood that exceed the levels that have been found to inhibit insulin secretion and increase blood glucose in animals and humans.
All fluoride toothpastes sold in the U.S. must now include a poison label that warns users to “contact a poison control center immediately” if they swallow more than used for brushing.
Just one 1 gram of fluoride toothpaste (a full strip of paste on a regular-sized brush) is sufficient to cause acute fluoride toxicity in two-year old child (e.g., nausea, vomiting, headache, diarrhea).
In 2009, U.S. poison control centers received over 25,000 calls related to excessive ingestion of fluoride toothpaste, with over 378 users requiring emergency room treatment.
In adults, fluoride toothpaste can cause skin rashes around the mouth known as perioral dermatitis as well as canker sores.
