Bukwang Sirinmed Gum Care Toothpaste

My teeth are very weak, so I go to the dentist often. I started using this because the dentist recommended it.
It is said that it fills in missing areas after brushing and even coats the tooth surface, resulting in lower tooth wear and helping to prevent damage to the tooth surface.
My tooth sensitivity disappeared about a month after I first started using it, so I have been using it consistently ever since.
I used to use Sirinmed F, but lately I've been trying Gum Care because it says it contains vitamins to care for the gums. I don't notice a big difference yet, and Gum Care is a bit on the thinner side.
