Do we have to fluoride application?

I heard that in case of Byeongseol kindergarten, fluoride application is applied. If you ask me if I should fluoride application , I'd advise you to do it. In fact, the fluoride application at the dentist is used to clean your teeth with a clean instrument, dry your saliva, and use 5% varnish. The fluoride in kindergarten or school is not completely removed from your teeth and you use 2% gel. You don't have to worry too much about the low levels of fluoride.~^^ I tried to produce the easiest word in the video. But if there was a difficult word, I couldn't think of the appropriate word. Please understand me.^^ How was it? Was my video helpful today for you all? If it was helpful, please like the video and subscribe to the channel. I will see you in the next video.
