National Toothache Day bangs on February 9 to give a gentle reminder about the importance of dental hygiene and care. The day is celebrated by educating and sensitizing about toothaches and the ways to prevent them. Ask about its terror to someone who has ever suffered from a toothache in the past. Usually, there is no show from its side for a while, but when the issue of toothache emerges, it draws all of your attention, peace, and sleep. Scientifically, a toothache is also named odontalgia in which a person suffers from pain in the mouth. It is caused by one, two, or multiple teeth and results in difficulty in sleeping, eating, and talking.
