I was facing problem in my teeth and I went to a doctor for dental checkup.doctor described me my problem in deep.before 2 years ago I had cleaned my all teeth from dentist but after cleaning he didn't polished my teeths and because of that I have facing cavity and food stitches in my all teeth and whenever I eat cold and hot things I feel a heavy felling of sensitiveness.
So he told me to use sensodyne toothpaste. I tried this and really it worked for me.now I dont feel cold and hot in my teeth. Slowly this toothpaste also helps to whiten your teeths but I am not sure about cavities that whether this toothpaste will work for it or not.
Sensodyne comes in various flavours like sensodyne mint, sensodyne cool get etc.if anyone has sensitive teeth use sensodyne and get rid of this problem.
