Can just gym membership be classed as therapy

primarily mouth guards are to be worn at night and not at any time when one eats.
The ache you mention is a sign in the morning that mouth guard may well be prescribed to assist pains/ grinding of teeth etc, thru the night, and of course can occur after using a mouth guard in the morning as the teeth and jaw get used to being without wearing of one.
Unfortunately teeth lose their enamel with chronic anorexia/ bulimia which in itself will cause mobility and hot n cold pain in the teeth.
Mouth guards are unlikely to give points .

Thank you for your detailed reply. May be it will help towards points if struggle with motivation. And having to exercise to allow my self to eat. All connected with eating. Inspired 4 points for this activity in 2016 but current assessment 0 points for everything. Although exactly same circumstances n position. It's a lottery of whomassesses you. It's so unfair. Thanks

O yes I do get pain with cold in my mouth I have been perceived some special toothpaste from dentist to put on my teeth and leave on as long as possible. It doesn't work entily but takes edge off. Mytmj means stiff jaw and mouth with pain. My teeth have moved and my teeth have moved making difficult to eat open my mouth and prounanes words.

I just want to know how I get points. How to word it. Thanks. What does the dentist need to say.
