Have you ever had a sinus toothache? If you have, you know how uncomfortable, distracting and painful they can be. Fortunately, tooth pain caused by sinus pressure or pain can usually be relieved significantly with proper at-home care. *Note: If you are suffering from extreme tooth pain of any kind, or tooth pain that lasts for more than 12-18 hours, please visit your dentist as soon as possible so that they can determine and treat the root cause before the condition worsens.
