I can feel a little cavity in my right back molar. Unfortunately, moving to La Crosse, I'm dentist-less for now. I got this little miracle worker at Wal-Greens for $7.00 - and amazingly fashioned myself a temporary filling until I have some time to get my tooth fixed. It tastes and feels a little funny, but oh well. Definitely a life saver for the next few days (which are going to be a whirlwind).
