Of all the unfortunate inconveniences caused by a toothache, being unable to sleep is always a major one. If you can’t see your dentist right away for treatment, try taking either ibuprofen or acetaminophen to ease the discomfort. Then, prop your head up with an extra pillow or lay back at an incline. Keeping your head elevated prevents blood from rushing to the tooth, which intensifies the pain. You can also consider rinsing your mouth with warm salt water and applying an ice pack just before bed.
