Happy National Skyscraper Day! 🏙️🦷
Just like skyscrapers are built to sway a little under pressure, your teeth have a little “give” too! The periodontal ligament acts like a tiny shock absorber, helping your teeth handle the everyday stress of biting and chewing.
Built strong, with just the right amount of flexibility!💪🏼😁
