National Toothache Day, February 9th, serves as a reminder of the importance of oral health and the discomfort toothaches can bring. Toothaches are primarily caused by dental cavities (caries), which result from tooth decay. Other causes are gum disease, tooth root exposure, cracked teeth, or jaw disorders. Caries have been detected in human fossils, indicating that dental issues have plagued humanity for millennia; oldest manipulation ("treatment") in a human molar in Italy dated 14k years ago. The first recorded reference to toothaches dates to ancient Sumer, around 5000 BC, described as "tooth worms". The main bacteria responsible for toothache are Streptococcus mutans and Lactobacillus (Caries), Actinomyces (Root caries), and Porphyromonas gingivalis (Periodontitis). Caries are much rarer in mammals that don't have a sugar-rich diet, or that have a more basic pH environment in their mouth, like cats and dogs. Dental caries is one of the most common health problems globally, affecting over 2 billion people and half a billion children. To combat toothaches and prevent dental caries, it's essential to maintain good oral hygiene practices: Regular brushing with fluoride toothpaste, flossing, reducing sugar intake, and visiting the dentist for check-ups and cleanings. Fluoride treatments and dental sealants can offer extra protection against cavities. More: https://bit.ly/3uoNdzk https://bit.ly/495PVJl https://bit.ly/48ZV1GS Art&Text supported by ChatGPT.

The Ex-Planet Pluto was discovered February 18 1930 by 24-yo Clyde Tombaugh at the Lowell Observatory in Arizona. Initially hailed as the ninth planet, it was reclassified in 2006 as "dwarf planet", sparking widespread debate. Pluto was named by an 11-yo girl from Oxford, England, named Venetia Burney. After learning of the discovery, she suggested the name Pluto, the Roman god of the underworld, to her grandfather. The name was passed to Lowell via the University of Oxford, voted, and adopted. Pluto orbits the Sun every 248 Earth years, and its highly elliptical orbit takes it closer to the Sun than Neptune for about 20 years. It has five known moons: Charon, Styx, Nix, Kerberos, and Hydra, with Charon being the largest and so closely bound gravitationally to Pluto that they are often referred to as a double planet system. The flyby of NASA's New Horizons spacecraft in July 2015 revealed a varied landscape, including mountains made of water ice, vast plains of nitrogen ice, and a blue atmospheric haze, challenging previous assumptions about its geologically inactive status. Tombaugh Regio, Pluto's heart-shaped feature, spans 1,600 km and showcases a unique composition of nitrogen ice, methane, and carbon monoxide, Pluto's surface area is roughly equivalent to Russia's, the largest country on Earth, yet its exploration has only just begun, promising new discoveries about the solar system's frontier. https://en.wikipedia.org/wiki/Pluto Art&Text🫶by ChatGPT.
