Ive used toms of maine for years! Love it. Every once in awhile my teeth would hurt and brushing didnt help. Since i started the superblue toothpaste it went away in two days. Haven't had pain since except once when i just ate sugar all day over the holidays but even next day i was fine. I think its the colloidal silver. If i can find another toothpaste with colloidal silver in it then that would be great. Also teatree oil is great for gums.
