In the Netherlands, the water is not fluoridated. Since food contains very low amounts of fluoride, it may be beneficial to obtain some extra fluoride in some way. My question: is it recommended by health authorities that all adults who do not get their recommended dose of fluoride from drinking water swallow their toothpaste?
In one portion of toothpaste, there is approximately 1.3 mg of fluoride. So if people ingest all toothpaste after brushing and do this twice a day, this will add 2.6 mg of fluoride per day. This would help to get to the recommended 3 mg of fluoride per day.
However, toothpaste also contains other ingredients. Would it be harmful in some way to always swallow all toothpaste?
