so i went to a new dentist and he thinks my sinus' are what's making my teeth hurt, which is surely possible with all this pollen! i had two cavitites filled recently and they are extra sensitive right now.. he told me to use motrin sinus to see if that helps but i can't find it anywhere!! is it sold over the counter or do i need a prescription?? i can use anything that contains ibuprofen and a sinus drug.. (besides sudafed, i get hives)

someone help me please
