Hello doctor, What ppm and percentage of fluoride are good for adults? I am trying to figure out what kind of toothpaste is good, but I hate mint, so I am trying to check the percentages of fluoride that is good for an adult.
Hello. Fluoride content can be around 1000 to 1200 ppm which is more than enough for the prevention of cavities. No need to go higher than that. More important is the proper brushing technique. Go for up-down or circular brushing technique without too much pressure onto the teeth to prevent wearing away of enamel in the long term due to abrasion.
