The current CDT code for a night guard depends on whether the appliance is hard or soft and whether it covers a full or partial arch. Here’s what D9944, D9945 and D9946 mean—and why older codes like D9940 should no longer be used.
Jaw popping and clicking are common and often harmless, especially when there is no pain or difficulty moving the jaw. Learn why the TMJ can make noise, when a pop may be related to TMD, and which symptoms deserve a closer look.
