Can anyone recommend a supportive pillow for sleeping on my back?

[Bluebiscuits]

After always sleeping on my front I am trying to train myself to sleep on my back as it is supposed to help reduce teeth grinding at night. I am waking up in the night with lower back pain, as I don't think my current pillow supports my neck well enough on my back.

Can anyone please recommend a decent pillow for back sleeping? Thanks 😊

Have a look at Groove pillows, I have a graveyard full of pillows trying to find one to help after an injury and this really helps, may take little getting used to.
