Throbbing in the back of my gums, occurs 2-3 times a day. been to a general exam, also had routine cleaning trying to find cause. they said theres no cavities there, just mild gum inflammation. i floss once a day, brush twice. should i be worried?

If your dental checkup is OK then there is nothing serious. Mild gum infection or food particles may cause your symptoms. If you can brush after every meal and try Sensodyne toothpaste. Good luck.

Do you still have your wisdom teeth? I would hope that your dentist explored this possibility if you do. When you say "back of my gums" it is difficult to determine what you mean... on the tongue side of your lower teeth? On the palate side of your maxillary teeth? Or does "back" mean the back of your mouth?

Could be due to your occlusion, a gum problem, or most probably wisdom teeth trying to erupt. See your Dentist for an evaluation w x-rays and, if necessary, referral to an Oral Surgeon.
