Have you checked out the Oil Pulling forum here on Curezone? I have dental problems also and not much has helped yet, but lately I have been reading about oil pulling and I am hoping this might be just the thing that will help. I've been doing it for about 3 days now and my teeth feel great, however it's too soon to say what is going to happen.
My general feeling is that you have to throw out all your ideas about dental health and rethink them all (how to brush and what to use, what really causes decay and problems, whether dentists and their treatments are helpful or a big part of the problem, how does fluoride affect teeth, etc.). I've completely changed the way I care for my teeth and so far I am happy, but I won't know for sure if I've solved my problems until more time goes by.
