Dear Dr. Manhart – We had a conversation about a month ago and I told you about this mysterious pain I get in my teeth in the evening. You thought there could be a problem with my front and suggested my dentist send you my x-rays. I spoke with my dentist and he studied my x-rays going back to 1977. Yes, there are two root canals that are failing in that exact spot. I recently had a full set of x-rays and he sent a copy to you. You should be receiving them. I’m grateful for our conversation and would appreciate any further suggestions. You zeroed in exactly where the problem is. By the way, since I’ve been using the calcium therapy (brushing and rinsing) the pain is less! Thank you, Warmest regards, – VB in NY
