The lines between dentistry and sleep medicine aren't completely clear yet, but we know there is a relationship and we can and should get to know whether our patients have a sleep disorder. On the one hand we can be a first line of diagnosis and advocate for overall health by screening for a sleep disorder. The other side is that sleep disorders are related to TMD, and present risk factors for the dentistry we provide so discovering them is a key to predictable dental health over time. I have found a quick easy screening tool that is highly accurate.
