<s>[INST] Hi, may I answer your health queries right now ?  Please type your query here...I am having a terrible toothache and when I stand up or lie down, I can feel my pulse in my tooth.  I can't stand this throbbing pain anymore but I can't afford a trip to the dentist.  Any suggestions? [/INST] Dear User,Thanks for using health care magic.From the available description it appears that there is infection in root of your teeth. The another possibility is of caries tooth which leads to raw surface and this gives sense of pulsation if exposed to low or high temperature.Visiting dentist is required as he can only provide the suitable treatment for condition after diagnosing it.Other than keep your oral hygiene in better form so there is no or minimal risk of repeated infection.'Hope I have answered your query. If you have any further questions I will be happy to help".Thanks </s>
