Dental health fluoride products

It is the same fluoride product I used in elementary school. I have been using it consistently because I think using it once a month will be good for my dental health. It is a tooth mineralization promoter containing fluoride ions, so it is said to strengthen and solidify weakened teeth by inducing the absorption of minerals such as calcium and phosphorus on tooth surfaces that have become porous and brittle, making them vulnerable to cavities and sensitivity. I like that it is simple to use, taking only 1 to 3 minutes and just once a month.
