Maltese pawing at her mouth like crazy

She has been pawing at her mouth like a crazy - was doing it when she first had most of her teeth extracted.. over a year ago, but started it again the past month or so. She has heart issues, so when she does this pawing, she sometimes will pass out. I need some answers. I do have a video as well, if that helps! When I touch the tiny front tooth in front of her mouth, or the gums around it and that is when she starts doing it as well. Seems sensitive or some nerve damage due to the teeth being removed? She does it at anytime but especially after eating or drinking. Wakes her up in the middle of the night.

Hello.  This is interesting - and potentially complex.  Presumably your vets are involved and I wonder, if they are unable to help, whether you / they have considered a referral to a neurologist, who specialises in nerves and neuromuscular connections.   It is difficult to say from my position whether this might be connected to a tooth, to jaw pain (a tumour or infection in that area, perhaps?) or whether indeed your cat may be fitting.  Pawing at the mouth can be a pro-dromal (pre-fit) sign, and you say that your cat loses consciousness afterwards, so this may well be something to consider.  It might help your vets or specialists if you are lucky enough to catch such an episode on film so that they can see what goes on at this time.  However, do not delay asking for help for this, as it is a matter of chance.   I would be very interested to hear what was found, should you get to the bottom of this case.

My apologies - I see now that this is a Maltese and not a cat.  However, the same remains true.
