I wear a retainer or night guard and wake with jaw ache
A guard sets your jaw slightly open and stops it settling. Side sleeping then pushes the lower jaw sideways against the pillow for hours, so the load runs through the jaw rather than the cheek. A pillow that is too low makes it worse by tilting the head down and increasing the sideways component.
This one is not a pillow question alone. A guard or retainer is your dentist's or orthodontist's, and any jaw pain is a question for them. This page describes only how head height changes the direction of load, and makes no claim about any dental condition.
What the pillow has to do
- loft in measured range — Pillow loft within the range your own measurement implies. This is first for every constraint in this cluster, because no surface is soft enough to rescue a pillow your head has already flattened.
- conforming top layer — A surface able to displace further than the object protrudes — typically a dual-density build with a soft top over a supportive base.
