On this week’s episode of Fast Facts - Perio Edition your host, Katrina Sanders, RDH talks to us about periodontal ligament fibers.    Quotes:    “That's why if you're a clencher and a grinder you wake up in the morning and you go, oh, my teeth are hurting, it's probably the periodontal ligament that's causing pain.”   “We can observe this radial graphically, although we cannot see the periodontal ligament itself on a radiograph we can see that PDL space and when we see widening of that periodontal ligament space, we know that that tooth may be experiencing a higher absorption of shock of the occlusion.”   Resources:   DentistRX: https://www.dentistrx.com  More Fast Facts: https://www.ataleoftwohygienists.com/fast-facts/    Katrina Sanders Website: https://www.katrinasanders.com  Katrina Sanders Instagram: https://www.instagram.com/thedentalwinegenist/
