Are you with someone for company? If so, it might be worth picking a film out with them, or finding something you like on TV.
If Im super stressed my lovely fiance will brush my hair or stroke my hand and arm, thats pretty relaxing, having your face stroked is nice too, but hands/touching nr your face might soon take you back to thinking about your teeth and so on. Lavender oil in a burner is relaxing, as are a few drops on your pillow.
If you're not with anyone, try Skype or messenger.. just try chatting to take your mind off stuff a bit.
Sometimes I go into a panic and then Im struggling, so its best to try and pull it back as soon as you can.. Ie, dont Google! Youll home in on all the horrible stuff and only make yourself feel worse.
Positive thinking, seeing the end goal..
Sometimes its really hard, telling yourself not to think about things wont work! Just think "Im going to be okay, everything will be fine, and if its not.. I can leave at any time. But it will be ok and Im taking the steps I need to fix my teeth and be/feel better"
..This is something I think Im gonna be trying when my treatment comes up, some of it has helped in other situations where Im anxious, so Im sure it will work in this situation too
