<s>[INST] Hello, I just recently went swimming in a chlorinated pool today and shortly after I started feeling tooth sensitivity. Because of the pain, I have not been able to eat. My teeth begin to hurt when I bite down on food, my top and bottom jaw touch, my tongue touches my teeth, or even when I breathe through my mouth. I have brushed and washed my teeth multiple times and nothing seems to help. Please help ASAP. [/INST] use Tooth paste for sensitivity . Thermoseal tooth paste is good for sever sensitivity. Apply a thick paste on ur teeth and keep it for 10 Minut and then brush..do this 3 Times dialy for a week </s>
