I think I understand you also.

I used to have what I think everyone has had at times in bed, those little dropsy sensations like falling slipping down in bed.......but thats not it.

I will be lying there and just 'fall up', and the bed will shake, and my wife will wake and ask wth just hit, and I tell her its ok, go back to sleep, Im ok. It passes, Im ok, and go sleep again.

Its like the "wobble' I said I have sometimes when out with my dogs, I will be walking and not have the world go round but fall into myself, and mistep but not lose my balance or anythinng, just whoops, and stand still a moment and it passes, and focus returns and Im ok with the dogs standing there looking at me.

Hope you have good luck with your teeth guy - sadly Medical docs know nothing about dental abcesses, stay with a DmD, he'll do right by you, and take his meds faithfully til he says you don't need more...Oral infections can remain low-grade enough that they do and will cause many central problems in and of themselves, as well as systemic problems.
