Problem with teeth. Bruxism related?

Ok go with me on this one, my back teeth on the bottom right side
feel strange, loose but they're not loose and like they've shifted out of place somehow, but they've not, they are slightly tender nothing major just a bit twingey, this has all started since sunday, I suffer from bruxism and had a particularly bad night of it, is it possible I've damaged my teeth in some way? I'm going to make an appointment at the dentist just to be sure but was just wondering if anyone had an idea what was going on so I could be more specific?
I brush my teeth twice a day and do all I can to keep them healthy, I inspect them regularly as I'm prone to mouth abcesses and everything looks normal, nothing has obviously changed. Is it possible to just have bad teeth no matter what you do?

Without looking at the teeth and your mouth, it's not really possible to say what the trouble is. You may have clenched hard enough to shift things, or to have damaged the teeth, yes. You may have cracked a tooth, or you may simply have a case of sore muscles and irritated nerves. What you really need from the dentist is a mouth guard to wear at night, so you don't grind your teeth. You can certainly be born with bad teeth- I certainly was. But mine is enamel hypoplasia, they were just not covered with enamel to start with, and there is only so much dentists can do for them. And you can have a higher than usual proportion of bacteria to attack your teeth- but that would tend to be kept in check with adequate dental care. And of course, if you have a problem like bruxism, you could damage the teeth enough to cause problems. You should have a talk over with the dentist to see what he recommends you do about it, but definitely get the mouthguard. All the brushing and flossing in the world won't help if you grind them down or break them.

by grinding, you can bruise the periodontal ligaments that are attached to the root of your teeth causing temporary pain. They will tighten back up and heal, but your dentist will probably recommend a bite guard to wear while you sleep. They run a couple hundred dollars and insurance doesnt cover it. They can however keep you from grinding your teeth down, future breaks and cracks, and temp tooth and jaw pain.

the strange feeling that u might be having is most probably due to the damage to ur periodontal ligament which are fibres that attach tooth to the bone. or may be due to excess pressure on the teeth there might be a little damge to the tooth which may be causing the pain. actually without looking at it its difficult to give the rightcause. a dentist can best tell u after seeing the case and u definitely need treatment for bruxism which varies as per the cause of bruxism.
