Ear equalization troubles? Often switching to a custom moldable regulator mouthpiece helps a lot. They cost only 20 bucks, you can form one in minutes at home, and it turns out reducing jaw fatigue isn’t the only benefit. What do jaw muscles have to do with equalizing, you ask?
Consider the Physiology of the Eustachian Tube. The Tensor Veli Palatini (TVP) muscle opens the Eustachian tube for pressure equalization and shares embryological origins and innervation via the Mandibular Nerve, with mastication (chewing) muscles. Due to this, tension in the jaw/chewing muscles can cause synchronous clamping of the TVP, restricting its ability to open the tube and resulting in difficulty with ear clearing!
Diving Impact: If a diver clenches their jaw, the TVP cannot function effectively to open the Eustachian tube.
Solution: Relaxing the jaw is essential for proper equalization. Use a moldable mouthpiece! In stock at Southern Utah Scuba.
