Dear Dr. Moore,
After visiting the dentist for re-filling of one of my molars which contains a rather big hole, I have been experiencing very sensitive dentine for more than 3 months. Whenever I eat hot and cold stuff, it hurts badly. I phone the dentist, he suggested me to buy a toothpaste with the brand called Sensodyne to take care of it. I did as he told me. But so far after 3 months, it improves only a little bit. I don’t want to go back to the previous dentist, because he may charge me a lot of money. What should I do? I hope you can help me. Thank you.
