Hi..I Am Having Sensitivity From Past 3-4 Days And Its

Hi..I am having sensitivity from past 3-4 days and its not regular.Along with that last molar teeth are not properly grown and upper ones on both side are not at right position as a result they have cavity(black).Yesterday at the back of upper molar teeth my jaws get swollen..I am feeling little pain but not bleeding gum..I visited doctor..he said nothing to worry and the condition is not much bad..He suggested Thermoseal tooth paste and Stolin gum paint to me along with one mouth wash... So bit confused if i dnt have bleeding gum then why he suggested Stolin..please suggest.I am having sensitivity not in complete jaws but sometime its in 2 teeth nd sometimes more than 2 .Its not ongoing problem.
