I visited a nearby dentist for tooth whitening of a dead tooth which was turning black. She applied a dental solution to make it white ,but it caused a sensitivity in nearby 4 tooths. It has been couple of months but the problem is sustaining. I was using sensodine as toothpaste in these 2 months. Post that I visited her and she suggested shy nm toothpaste twice a day by applying on sensitive teeth for 10 minutes before brushing. She has given nerve inflammation antibiotics as well to calm the sensitivity down on the selective teeth. Can anyone suggest me what should be the course of treatment ahead .will the sensitivity go in time.
