Just catching up with this thread and wanted to add to it. I had a lovely mum but unfortunately she died young, I miss her every day. Around the time she was dying of cancer I started to grind my teeth - must have been due to the anxiety, but I was never aware of it, I only knew because my dentist pointed it out. I have never been able to kick the habit (mainly because I only do it when I'm in a deep sleep) so I wear gum shields at night permanently. I bite through them in about 2 years and then just replace them. It's just something I have live with I guess - hope this helps x
