Are you a mouth breather? Do you have difficulty swallowing? Do you have a lump in the throat? Do you have jaw pain and headaches?

By working on proper nasal breathing, you can relieve the symptoms increase focus and feel normal. #mouthbreather #mouthbreathing #tmjdisorder #tmj #headacherelief #tensionheadache | Dr. Joe Damiani
