You feel your whole body aches when you have toothache. A toothache happens if tooth decay penetrated the pulp chamber or is very close to it, which contains the nerves and tiny blood vessels. Ideally for a toothache is to undergo a dental treatment at once. RCT is a more conservative way of treatment comapred to tooth extraction. Most common are Paracetamol, Aspirin, and Acetaminophen.
Ice is excellent in numbing nerve endings.
Try to compress the affected area with ice. But if it aggravates the pain, discontinue it. You may wonder why toothaches usually strikes at night when you lie down to go to sleep. The cause is the increased pressure towards your head. Keep your head elevated to decrease the pressure in the area.
