I had a tooth 13 pulled and I quit eating and chewing that side totally for 2 months waiting for the extraction whole to shrink, I then am forced to the other side which I avoid at all costs because of severe teeth sensativity. Teeth 2,3 4,So now its not sure how to act having hot and cold near them so I started using sensative toothpaste and started using a waterpik my 3 teeth that are horrible sensative, I started having little twinges of pain. Its not a tooth pain more like gum pain, also my jaw was sore, I have tmj but havent had a flare up in over 10 yrs. I stopped the waterpik and the sensative toothpaste and started flossing, I wasnt flossing because the floss wouldnt fit finaly I found one that works, during my recent flossing the gums are bleeding pretty good, just the 3 sensative teeth I have been bugging. I have today gone to a new dentist they are running a free exray and exam, the dentist was very thorough he did a cold test first, zing zing zing, then he did a electric current test, again zing zing zing. He then takes the tool to the gums on these teeth and says 6mm pocket, and a 5 mm pocket. He said he see's 2 small cavities under the fillings, here comes the salesman,lol you can put 2 crowns over the teeth a new build up of course, and that might help with the sensativity. I said we need to start with a cleaning dont you think he says yes that might help. OMG, so confused. Is the pain I am getting whch feels like its in my cheek too, is this gum disease? He didnt elaburate on the gums at all I think sales of some crowns which I have none and never wanted any. These fillings are at least 37 yrs old they are silver and I have had zero troulbe with my teeth. The teeth dont hurt. What should I do? would it help right now to salt water rinse? None of this started until I started the sensative toothpaste or waterpik, and yes the flossing seems to have made it worse. Thank you and I am so sorry its so long, hopefully I explained it ok
