Re: I need help with tooth sensitivity pretty please! PS lasting negative effects?

Having mercury Amalgams removed by a typical dentist can do more harm to the system (at least temporarily) than leaving them in the mouth. Biological dentists follow certain procedures not only to minimize mercury exposure, but to make sure all the mercury is out. Standard dentists don't address either these things so its tough to say in what condition your teeth were left. Having swallowed that large amount of mercury certainly can pose risks but hopefully your digestive system was able to expel it (rather than getting stuck somewhere).
Teeth have to be reduced so that a crown can be placed, and this alone causes extreme sensitivity if the crown wasnt properly placed on doesnt fully cover the tooth. I have a crowned tooth that bothers me with very hot or cold drinks.
Unfortunately crowns can be just as bad as Amalgams because they are typically made with nickel, or even worse, palladium. Dentists must keep track of the type of crown that was placed so you might be able to ask them. Most likely your dentist will think your nut in wanting that information but you might be able to get away by saying that your having a ring made and need to know the metal composition of the crowns so that you can use similar metal composition for the ring to avoid any complications or interactions.
I would have the crowns replaced if they are made of palladium or nickel; its even worse if the crowns are made of dissimlar metals as battery like effects in your mouth can degrade your teeth even further and affect the energy flow through those particular meridians.
I would also look into your diet to solve some of the allergies (the juice fast could have given your body a break on typical allergens found in food)
Good luck
