I have similar pain on one side (right) of my upper teeth and lips and the pain usually come
back after 23hrs every day that is from 4pm every day. I have seen my dentist and did
not find any problem inside my mouth. My only pain relief was one dose of Nurofen everyday at 4 pm because that was when the pain returns. My dentist told me not to take Nurofen anymore but I can't. I do not know what to do next but if your share any relief or experinces of how you recover from this problem would be very much appreciated.
