Hi\n\nI have a sharp pain on one of my back molars that like a stabbing pain and it occurs on and off and sometimes all the time. Sometimes it spreads to other teeth. I used to use Listerine every night after brushing but I’ve recently stopped as I’ve heard it can strip enamel. Work colleuges have told me it’s gum disease so I use corsodil once a day to see if it helps. I use oral b pro sensitive gental whitening/enamel repair and the pain still thier. What could it be????
