I have a number of cavities, but having had bad experience of dentists in the past, i only go if i get bad pain. I havent had any for several years. I started the methylation protocol about a week ago, and the day before yesterday my teeth started aching. At first i thought it was just a tooth had got bad, but then another tooth started aching too. and then anohter. all my dodgy ones are hurting now. This got me wondering why. Could it be some kind of change in my immune system? Perhaps brought on by starting the methylation cycle? Its the only thing i can think of that has changed. If so, then pain aside, i guess this is a good thing.
