Teeth Comfort (ya zhou yan wan)

You need to take it as soon as you feel any dental issue - immediately. The problem resolves faster that way. Also, a Chinese Herbalist once told me that it's best to start with a double dose.

Stuff works...it does need about four or five bottles...my dentist was so impressed she asked for details about it as she saw the progress!

Didn't work for me, but I know at least three others who swear by it. I used it for tooth pain after prep for crown. I finished one bottle and had purchased several b/c I was told it sometimes takes that long. They felt results right away. I did not, so I guess that's why I did not continue.
