Jaw Training: Mastic Gum vs Jawliner for Masseter Hypertrophy
Jaw training mastic gum versus Jawliner devices differs fundamentally in resistance consistency and time under tension control. Mastic gum provides 10–15x variability in bite force application depending on bolus size, saliva saturation, and masticatory fatigue, while Jawliner and similar silicone resistance tools deliver calibrated, progressive resistance in the 20–60 lb range. For measurable masseter hypertrophy … Read more
