A pea-sized amount is enough for adults and rice-sized for kids :)

Thank you for the great question, I get that a lot in my clinical practice! So it’s very similar with toothpaste as it is with cleaning your car or doing the dishes- if you just pour it over and then rinse it, it won’t do much! You have mechanically remove the dirt, the toothpaste will only help (and it has some beneficial ingredients). In summary, the toothpaste is not the most important factor, but if you want some examples, here it goes: - If you have very average dental hygiene routine and not against fluoride in the toothpaste, then I advise one that contains fluoride. In any case, you don’t really ingest the fluoride if you spit out the remaining toothpaste after cleaning. - whitening toothpastes do more damage than good. If you want your teeth to be whiter, a professional tooth whitening is best:) - If you have sensitive teeth, then a toothpaste that is labeled for sensitivity is advised. There are some more tips and trick for alleviating sensitivity coming up! - If you have gum disease, then special techniques for cleaning the interdental space are required. Hope that was helpful!
